so I just bought this card cause I use lots of storage space pretty quickly, My question is wtf is going on here? it just sticks on "checking for errors" and never gets past it, it mounted up once and while I was dumping files on it over USB from my computer (in usb mass storage mode) both it and my internal storage just disappeared, the copy operation failed, so I restarted the phone and I have yet to get the phone to mount it since then.
I'm running eclipse 1.3rc2, is this because of the sd flip-flop, the size of the card or the fact that it's class 10?
the card works perfectly fine in my camera, and in multiple PCs, but as soon as I stick it in my X2, it just doesn't want to work.
I noticed the stock SD card has a "bootable" partition flag, whereas this one doesn't. maybe this is my problem?
also what filesystem should I use, I run linux on my PCs so I can do whatever I want with it.
what if I just delete its partition table, put it in the phone and then let the phone format it? I've reformatted it with my PC and no dice.

When I got the 8gb card and using now it was acting weird ...would copy files when in the phone. I formatted it using the phone and it has worked fine since.
Good luck.
I can't say it will work for u but it cured the problems I had at the time.
just make sure u format the right card since in eclipse its switched around and recognized as internal in menu.
well, It took exchanging it for a class 4, and now it seems perfectly fine.
so note to self (and others)
NO CLASS 10 CARDS IN DROID X2, IT DOESN'T FN WORK!

I don't think that is true...I thought I saw plenty of users say they use them.
Mine is class 6 and works just fine
Did u try formatting from in the phone while stock? Don't know if that would make a difference at all
I didn't read one single thread from someone successfully using a class 10 card without having issues, sometimes it took a few days/weeks, it only took me one mount/dismount cycle.
besides, the class 10 cards, while having a higher sustained transfer rate, their seek times and random access times are overall slower. basically these class 10 cards are ONLY good for digital video cameras and things that don't actually utilize a filesystem.
that or they're getting cheap chinese cards that are just remarked class 6 cards, the X2 can't read and write to a class 10 fast enough resulting in data corruption, period.
Yeah im not arguing
I understand what ur saying now
I can confirm class 6 being completely fine tho
I think the "issues" I had was the file size I was trying to transfer(4gb)
I don't think it's the class rating but the capacity. In my experience 32 gb cards just aren't as reliable as smaller-capacity ones. Perhaps it's a consequence of packing too many memory cells into such a small form factor, I don't know, but I've had three 32 gb micro-SD cards fail on me since the beginning of the year, whereas not a single 16 gb card has failed me yet.
I just dumped 4.8gb of crap on it, over usb and it took it like a champ, it's also significantly faster than the stock 8gb card in terms of mounting, remounting, scanning my media and even opening up fileexpert is faster.
class 6 i'm sure is fine, probably the best balance, but I can even take HD video straight to this card with no frame dropping or glitching. it's currently playing hd video on my hotel room TV right off the SD card w/ no issues (the stock 8gb couldn't do that)
Ha. Mine came wit a 2gb class 2 sdcard ...
Wait...now that I think about it.. I had bought a droid pro initially. It had a screen issue...I took it back and paid extra to get the x2. Then I told em I didn't wanna lose my pics/video I had taken and he switched the cards. So I guess he basically just kept the one I wax supposed to get instead of moving my data to the new one....prick...

I'm moving the data off my stock 2GB card to a SANdisk 8GB Class 4 card to gain more media performance.
I understand FAT32 is better than FAT16 in this respect...
In fact the Hero formatted the card as FAT32 so assume it prefers it
Now, copying to the card, my Mac is copying very very slowly, far slower than the stock FAT16 card did.
Is this normal ?
Well done a bit of testing and the Album app is waaay slower on my class 4 8GB card formatted as FAT32.
Images in grid view and filmstrip view pop up more or less instantly on the stock 2GB FAT16 card.
On the FAT32, they appear as grey boxes before being filled in one by one with the actual image.
Note.
I've cleared Album's cache and data to force a rebuild of thumbnails, that thats not the issue.

ive noticed this aswell as i got me gf a hero at the same time as i got mine but only got a 8gb sandisk micro sd cardfor myself.
Her album photos with about 20 photos in is sweet as but when i scroll thorugh mine also with about 20 photo's in i have to wait for the grey boxes... when i got my 8gb card tho i didnt format nothing just plugged it straight in and started using it. everything else seems a little faster though compared to hers
My 8GB card was used in a Nokia N85 before so I had the Hero format it for me.
Assuming this would prepare it for use correctly...
Gone back to the stock 2GB card and all is zooming along nicely again.
Are you sure this isn't a caching issue guys? It may be slow to load on the first time while all the thumbnails are generated, but should be snappy afterwards. I would however be worried abou transfer speed between the SDHC Card and Mac as that should definitely be faster than a class 2.
When I changed from a class 2 to a class 6 I would say my read/write speeds doubled (or just over), I seem to get about 6-7MB/s when writing to it.
Have you tried writing to it when not in the phone? That will probably give a slightly better (or more realistic) reading.
Its not caching, I already tried clearing the applications (Album) cache and allowed it re-create its thumbnails in grid view and filmstrip view.
Opened each album and waited while it created them all.
Restarted the Hero and then went back to Album.
Still very slow compared to the 2GB card. No idea what class this is as it doesn't appear to say (writing on the backside is almost too small to read).
Writing to the card via my Mac starts fairly quickly, slows down to a real crawl and then a few minutes later speeds up again.
Worked fine in the N85 and recorded and played back video at a much higher bandwidth than the Hero can do.
FAT 16's limit is 2GB. so if you want to use a larger card then 32 is the way to go.
http://en.wikipedia.org/wiki/File_Allocation_Table
Thx for the info...
The problem I am seeing though is that the FAT32 formatted card appears to be far slower than the FAT16 card.
i forgot to add in my previous post that backing up the data to my pc was very fast on both cards, the only slow down i get is with the album app, exactly the same as joemax.
apart form that everything else is faster than my gf's 2gb card.
im gonna try backing up my data and formatting the card as i never tried that the first time
will report back with any findings.
edit:
tried formatting but made no difference, is fine with just 8 photos on, but once you start going to 20+ you get the grey box syndrome, which only last for 2 seconds or so before they appear but ofcourse would be nice if it was ultra smooth. could be that our sandisk 8gb class 6 cards are fakes .. i got mine of amazon for £15. i wouldnt of thought so but you never know, as everything else on the phone is running sweet.
I formatted the 8GB card in the Hero and in the card reader plugged into my Mac...
No change is speed at all.
Album is definitely far slower on the 8GB class 4 SanDisk card.
I just bought a generic class 4, 8gb memory card and the lag was terrible took an age for anything to load, so i went and got a class 6, 8gb card and the speed is back up to what it was when it came with the 2gb card. I strongly suggest anyone not to buy anything but a class 6 card.
Thx. Will look out for one on my travels.
Anyone know what class card the Hero ships with ? Mine does not say, if it does the writing is far too small for my eyes to read.
Heya Joemax,
I think you're getting the same problems as quite a few others. It seems to be some kind of problem the Hero is having with certain cards.
The problem being that it does not create and store the thumbnails for the Album gallery. The folder is created but the files are not. We are currently trying to work out why this would be, but i'm sure it's some kind of SDHC incompatibility with current Hero ROMs.
Taking delivery of my phone soon.
What's the latest on microSD cards?
Are 32GB worth it? Do they work?
Any particular minimum Class I should get, even if I have to get 16GB?
Thanks

I use an 8Gb, class 4 without any issues. Resco is installed on the card.
Although if your going to flash a ROM from a micro SD card use one < 8Gb.
Thanks,

From my experience, it's not the class or size that matters. It's the make. (Obviously a smaller card with a higher class will have faster r/w speeds, but that's not usually a noticeable issue.)
I never buy any SD cards now that are not SanDisk, and I can't remember the last time I had one that didn't work.
Some brands seem to get a lot of complaints.
The class wouldn't really matter if you're just using it to store data/apps.
I use a Nokia N900 and run Android off the SD card. A higher class gives a better speed when running an O/S off of one. But using one to store data/apps wouldn't give a noticable advantage of one class than another.
Obviously the size does matter but depends on what you'll use it for.
Plus for flashing use < 8Gb.
Thanks,
Al
PS. I agree with the brands. I don't buy cheap non-branded ones. Although I've never had an issue with any of the 'cheap' ones.
The size of the card depends on your needs. If you cram a lot of stuff in there or apps, then aim for 16gb or 32gb.
You can find 32gb on amazon from $70 up (sandisk, kingston, dane elec -- those are deem legit 32gb cards) and most of them should give real class 4 performance (even when they're listed as class 2 like sandisk).
For me I like San Disk,but I want to test Toshiba 16GB Class4.The seller told me that Toshiba quality is good also and I decided to buy it.
Never had any problem with file transfer and running android on SD card.
I've used it 4 months now.So far so good.
I use a kingston 8gb class 4.. Never had any issues with performance
Thanks for all the replies guys.
I'll probably run Android off the card initially with the standard WM 6.5 tweaked. Maybe put some SatNav on there too.
As for Apps depends what I come across. For WM I have an old large build of offline Wikipedia and some dictionaries etc.

I had my 8GB SanDisk in my G1 for 2 years, then my HD2 for about 8 months, then randomly one day it stopped working.
If I plugged it in, all of my content appeared on the phone such as pictures. Then after about 30 seconds it would freeze, and then the phone would say no SD card is inserted. I managed to copy all of my pictures across on the PC luckily before it froze.
Granted it was old - but they do fail after a while.
Going from a 2 gig SD to an 8 gig SD..
Is it as simple enough that i just make a copy of ALL the stuff on the original SD and copy it to the new one?
/EDIT- is anyone running an 8 gig SD with no problems, i heard its gotta be a class 6 or ill get unmounting problems?
If you don't use an ext partition just copy and paste your files.

dont buy class 4 sd card of any size. class 4 cards dont work with optimus one. they will keep unmounting. any other class or size card will work. aka class 2,6,10
the class of the card is determined by the clad number depicted on the card itself. a class 2 card will have the digit 2 written inside a small circle. same way with all other classes.
higher class means faster operation and probably more cost.

Since I keep seeing vagueness wrt exactly what the class rating of an SDHC card means, I'll spell it out:
Class X: guarantees MINIMUM write through put of X MB/s period nothing more nothing less.
i.e. read speeds can be anything as they're not mentioned by spec, latency can be anything again as not mentioned by spec, etc.
In the pre-SDHC days the VERY best uSD cards were those made in Japan by Toshiba(only manufacturer of uSD cards in Japan, might be re-badged but made in Japan is the giveaway). They maintained good read/write throughput and relatively low latency even when full. (All of those numbers tended to decrease as a uSD card became more filled.)
Made in Taiwan were next up. Passable, but no where near as good as Japanese.
Made in China bottom of the heap. I'd really only recommend using them if you had no other choice. Or could get by with R/W throughputs and latencies that were relatively poor and got much worse as the card became filled.
Also note there DOES exist a fairly rare pre-SDHC 4GB uSD card. I've never seen one personally but I know that they exist. Most were 128MB - 2GB.
Not sure if this still applies with SDHC as the controller electronics were changed and the min. write throughput spec added (mostly for video recording!).
All of this said I've got a PNY class 4 4GB uSD card that I'll have to try. The card is badged as PNY so I'm not certain who the mfg actually is. I'll see if I can't dig it up later IF it actually works correctly. (Only bought some of these since a b&m store actually had them at a close to decent price of $10 and they were suitable for my other devices.)

I have a class 10 sd card, but its made in china and its very low quality.. The read and write speeds are totally unpredictable. Sometimes i get read speeds of 20Mbps, but other times, i get 2-3Mbps. It is these kind of low quality cards that you must avoid. Good quality Class 4s will not cause an unmount.
Eg: Sandisk Ultra (Class 4) are way faster than Transcend (class 4)
(From what i have seen personally)
One more thing, it was reported that Android 2.2.2 fixed the unmount problem. So, incase you experience unmounts, you can even try using a 2.2.2 ROM.
I have class 6 transcenfld and it's super fast. Around 11 mb write and 20 read.

PS. this problem exists just in Froyo when u partition your card to install programs on SD. if u don't wanna use this feature... or if u wanna use Mik's Gingerbread... take any microSD you want. but if u wanna use this feature i think Patriot Card would be better.

simple copy past is not working if you are using app2sd.
if u copy and paste u will have to reinstall all the apps but the data will be ok try titanium backup (did not tested titanium, but fkd up everything when i tried with copy and paste )

As I have seen many on here talking about and buying various 64gb ranging from class 6 to class 10 / uhs 1..
I see people running speed tests and all around touting their happiness with it's performance in the SGS3.
So my question is how many, if any, have a problem with their SD on their SGS3?
Provide, if you would be so kind, any details that would help, such as brand, size, model.

Everyone posting success with their 64GB sdxc, can you specific how you sync your media to the card?
Just straight drag and drop, Windows Media Player, Media Monkey, Songbird etc ?

I am having great problems with a 64gb Class 10 card. If the data is copied to the disk before being inserted in the phone it registers as a damaged card.
However if you clear all the data via the PC then insert the blank disk it is recognised normally. You can then transfer the same data via a USB link from the PC via the MTP application. You may well have to load the Samsung USB drivers.
Sadly if you restart the phone it immediately reverts to the damaged card error message and you have to go all through the same procedure again. No ideal.
Over the years I've owned about every brand of cards from eBay cheapo's to the best the industry has to offer like Samsung. I shoot HD wedding videos, take millions of pictures and edit so micro SD cards have been a necessity.
It just dawned on me today when I was looking at the mountain of SD cards I have in my office and realizing the life span on all the cards I've used over the years. Therefore, I'd like to share my experience along with asking those who are knowledgeable in the area of memory cards to help answer some of my questions.
I shoot HD videos and take lots of pictures on my Note 3 so having a reliable card is very important to me. Currently I'm locked and loaded with a 64GB | Class 10 | SanDisk microSDXC UHS-I card in my Note 3. (I also have a Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM), which I use in my Canon Video Camera and it is by far the best card out there. Period.)
The 6 most reliable cards that I've owned throughout the years: (Best to Worst)
Samsung
A-Data (Samsung chip, go figure. However, they are highly likely Samsungs '2nd hand' chips as they are not as fast as the actual Samsung brand labeled chips.)
PNY
SanDisk
Kingston / Sony (tie)
Transcend
It's not worth listing the other non-brand ebay junk so I've left those out.
Lately, I've been very disappointed with SanDisk's quality. Especially with their Class 10 cards, where I have found them to have a very weak 'integrity' in their chips. A good card should give you about a million write cycles. (Write cycles is a whole another can of worms...)
I have had more failed SanDisk's (lemons) cards than any other brands combined. This is why I will never buy SanDisk again and am switching to what has never failed me, Samsung. I can't afford the chaos and hate having to recover priceless wedding pictures from a card who decides to kick the bucket when you need it the most.
Recently my 64GB | Class 10 | SanDisk in my Note 3 decided to go belly up and I had to use a data recovering software to salvage all my 4,000 pictures and hundreds of HD video's. WTH right? This card is a couple months old. My previous SanDisk in my old Note 2 did the same thing after a couple of months.
ME, MYSELF AND MICRO SD CARDS...
With a new card I reformat it to Fat32 with Disk Utility (Mac) and then pop it in my device.
Since I take a lot of pictures / videos, I connect my phone to my computer (Android File Transfer, works flawlessly on Mac), copy over everything to my hard drive, back it up again if it's important and then properly eject the phone/card. I've always read and heard from camera guru's that it's best to reformat your card from the device instead of deleting the pictures in the folder from your computer while it's still connected. Therefore, after copying over the pictures/videos I would immediately eject and delete directly from the phone. The 'theory' surrounding this is that if you leave your card connected to your computer, it will access (checking byte order/changes) the directory more times than you would want it to thereby decreasing the life expectancy of the card.
Now of course it's not convenient or practical by no means to do this every day with your Note 3...most people just plug in and play with no problems whatsoever throughout the life of the card.
QUESTIONS FOR THE GEEKS
Explain the difference in the structural integrity of the internal SD card vs external SD card.
How much more life expectancy / write cycles does the internal card have vs an external card?
For a heavy user like me I have always put everything on the external card to avoid using the internal memory as much as possible avoiding unnecessary stress.
How often should the external card be reformatted for a heavy user like me where I'm constantly copying over, deleting, etc...
To be continued...
I don’t know about card in deep technically but all I learned so far, generally cards these days have very long life span, at least average 10 years, unless physically damaged or any uncommon technical issues.
I too concerned about this too earlier but now technology is so fast upgrading you shouldn’t worry about its life span. Technically what I know its life span also depends on it read and writings like you said and even if your car had heavy use then there is no point to formatting it frequently. Card is not like windows which creates junk files by time. Deleting and formatting does the same thing and both will free up same space if you delete all, where formatting read or write more data than deleting. So formatting frequently could reduce its life but that could be unnoticeable. The same way defragmenting, shredding also reduces its life. But shredding is good if I lost it any other couldn’t restores any private files.
So I think there have no logic to format it frequently to keep it healthy, unless its corrupted.
By technology is so fast upgrading what I mean is like, few years back I brought a new phone and brought the best card at that time, it was Samsung 32GB class 6. It was best on the market during that time. But then class 10, pro, plus released. Then when I got note 3 I had already a 32 GB card but I brought a class 10 pro one due to the HD recording. So after 5 years from now even if this card is working I will still have to buy a new one, as there will be far better technically upgraded one. I hope I make sense.
And I too use Internal memory very less, as loads on internal memory make the phone slower.
Thanks for the reply. I agree that with a decent name brand of a card, the life expectancy shouldn't be too much of a worry. My experience with SanDisk has been pretty poor in that I don't think they make cards with good quality material. As mentioned, the structural integrity is very weak. Their older cards were better. The newer ones in my opinion and from my experience have to be treated with a mentality of 5 years ago, because they do wear noticeably.

I don’t know about card in deep technically but all I learned so far, generally cards these days have very long life span, at least average 10 years, unless physically damaged or any uncommon technical issues.
I too concerned about this too earlier but now technology is so fast upgrading you shouldn’t worry about its life span. Technically what I know its life span also depends on it read and writings like you said and even if your car had heavy use then there is no point to formatting it frequently. Card is not like windows which creates junk files by time. Deleting and formatting does the same thing and both will free up same space if you delete all, where formatting read or write more data than deleting. So formatting frequently could reduce its life but that could be unnoticeable. The same way defragmenting, shredding also reduces its life. But shredding is good if I lost it any other couldn’t restores any private files.
So I think there have no logic to format it frequently to keep it healthy, unless its corrupted.
By technology is so fast upgrading what I mean is like, few years back I brought a new phone and brought the best card at that time, it was Samsung 32GB class 6. It was best on the market during that time. But then class 10, pro, plus released. Then when I got note 3 I had already a 32 GB card but I brought a class 10 pro one due to the HD recording. So after 5 years from now even if this card is working I will still have to buy a new one, as there will be far better technically upgraded one. I hope I make sense.
And I too use Internal memory very less, as loads on internal memory make the phone slower.

I know that feel of losing data, I have had 3 64 GB SanDisk cards die since January - right now I am using a 8GB. sad n true
Wow, sorry to hear. That sucks. Then again, you've verified my point even further about how crappy SanDisk cards have become.
Let your next card be a Samsung. I'm weeding out my stock of cards, heck I've given some away already.
Here's the best: Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM)
I use it in my Canon and it's extremely fast.

That Samsung card sounds impressive, just not ready to spend any more monies on getting one right now.
off subject are you still in Honolulu..

Thanks for the reply. I agree that with a decent name brand of a card, the life expectancy shouldn't be too much of a worry. My experience with SanDisk has been pretty poor in that I don't think they make cards with good quality material. As mentioned, the structural integrity is very weak. Their older cards were better. The newer ones in my opinion and from my experience have to be treated with a mentality of 5 years ago, because they do wear noticeably.

I never used any SanDisk card on phone, only Samsung cards so I’ve no personal experience and I’ve seen many user complains about its compatibility and issues on Samsung device. However I’ve been using a SanDisk high-speed MMC card on my Nikon SLR over last 5 years and still its performing great.
I believe Samsung cards works great in Samsung devices. So far only one card got damaged many years back and that was a stock Nokia card.
I currently have a 64gb sandisk class 10 in my phone I always used sandisk and never had a issue. I can't say the same for kingston. I found out it doesn't mess up when you unmount it when taking it out. I never did that before and they got messed up even if it did get messed up warranty is always there.
currently using the sandisk extreme plus 64gb card with no issues whatsoever. will update this thread once it crap out on me (it probably will in about 6 months) and how the warranty process goes.
I had a 32Gb Sandisk Extreme die in my Galaxy Note 3 while recording 4k video on to it.
Without a compatibility list and guarantee from Samsung, I am reluctant to buy another high end microsd card.
I am sick of these SD Cards. In my Galaxy S3, the thing would ocassionally take a dump and have to be reformatted.
Now I just restarted the Note 3, and boom, card took a dump.
I think I'm going to just live without.
Sandisk has always been reliable for me, apparently there are only 4-5 chip manufacture, and majority of a-data's card are rebadged from sandisk, same goes with transcends, whiles kingston are with toshiba, and PNY is a mix of sandisk and toshiba.
For data recovery and/or SD card repair, had anyone given Spin Rite a try?
I've been using a UHS-I 16GB Team card in my phone, been pretty reliable so far and gets pretty quick read/write speeds. Also been using a 32GB UHS-I Samsung card in my Sony NEX-5T camera, also been having no issues.
Just had my first Warranty experience with SanDisk. My 64 Gig SanDisk Ultra had crapped out by not allowing any write cycle this would not allow for deleting files or format or any changes to card. After a brief chat session on the SanDisk website I had my RMA and got emailed a label to print. My old card was off to SanDisk. 10 days later the new card arrived. This was a good warranty experience. Hope the new card will have more writes.

I'm glad I'm not alone on this. I have my first 64GB microSD on Jan last year. I chose Sandisk because I believe many of tech experts favor them over every other brand. At the time I wasn't at all concerned about its lifespan because I am using it for such a simple task like music storage. By the end of Dec last year, the card refuses to write and format. Folks at Sandisk forum suggested to use SDFormatter, however if you get "write protected" error, your card is not repairable, they say.
I was lucky to get a new one so close to the end of my one-year warranty. But seeing Sandisk cards are getting less reliable these days, I might give Samsung a try if my Sandisk fails again.
Quick question, though: where else does Samsung evo and pro differs beside speed? Does pro have longer lifespan?
Interesting. I've been using Sandisk for well over 10 years in everything from my DSLRs to my phones, never had a single card die on me.
I have owned 3 64GB Samsung MicroSD's over 2014 and they all died within two months.

I agree with you, sandisk is probably the most reliable brand available.
Been using sandisk when the first had them as transflash.

Over the years I've owned about every brand of cards from eBay cheapo's to the best the industry has to offer like Samsung. I shoot HD wedding videos, take millions of pictures and edit so micro SD cards have been a necessity.
It just dawned on me today when I was looking at the mountain of SD cards I have in my office and realizing the life span on all the cards I've used over the years. Therefore, I'd like to share my experience along with asking those who are knowledgeable in the area of memory cards to help answer some of my questions.
I shoot HD videos and take lots of pictures on my Note 3 so having a reliable card is very important to me. Currently I'm locked and loaded with a 64GB | Class 10 | SanDisk microSDXC UHS-I card in my Note 3. (I also have a Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM), which I use in my Canon Video Camera and it is by far the best card out there. Period.)
The 6 most reliable cards that I've owned throughout the years: (Best to Worst)
Samsung
A-Data (Samsung chip, go figure. However, they are highly likely Samsungs '2nd hand' chips as they are not as fast as the actual Samsung brand labeled chips.)
PNY
SanDisk
Kingston / Sony (tie)
Transcend
It's not worth listing the other non-brand ebay junk so I've left those out.
Lately, I've been very disappointed with SanDisk's quality. Especially with their Class 10 cards, where I have found them to have a very weak 'integrity' in their chips. A good card should give you about a million write cycles. (Write cycles is a whole another can of worms...)
I have had more failed SanDisk's (lemons) cards than any other brands combined. This is why I will never buy SanDisk again and am switching to what has never failed me, Samsung. I can't afford the chaos and hate having to recover priceless wedding pictures from a card who decides to kick the bucket when you need it the most.
Recently my 64GB | Class 10 | SanDisk in my Note 3 decided to go belly up and I had to use a data recovering software to salvage all my 4,000 pictures and hundreds of HD video's. WTH right? This card is a couple months old. My previous SanDisk in my old Note 2 did the same thing after a couple of months.
ME, MYSELF AND MICRO SD CARDS...
With a new card I reformat it to Fat32 with Disk Utility (Mac) and then pop it in my device.
Since I take a lot of pictures / videos, I connect my phone to my computer (Android File Transfer, works flawlessly on Mac), copy over everything to my hard drive, back it up again if it's important and then properly eject the phone/card. I've always read and heard from camera guru's that it's best to reformat your card from the device instead of deleting the pictures in the folder from your computer while it's still connected. Therefore, after copying over the pictures/videos I would immediately eject and delete directly from the phone. The 'theory' surrounding this is that if you leave your card connected to your computer, it will access (checking byte order/changes) the directory more times than you would want it to thereby decreasing the life expectancy of the card.
Now of course it's not convenient or practical by no means to do this every day with your Note 3...most people just plug in and play with no problems whatsoever throughout the life of the card.
QUESTIONS FOR THE GEEKS
Explain the difference in the structural integrity of the internal SD card vs external SD card.
How much more life expectancy / write cycles does the internal card have vs an external card?
For a heavy user like me I have always put everything on the external card to avoid using the internal memory as much as possible avoiding unnecessary stress.
How often should the external card be reformatted for a heavy user like me where I'm constantly copying over, deleting, etc...

Lifespan? Didn't know they were supposed to "die", or even wear out, and stop working eventually. Been using this same SD card for the past 2 years, and works like the first day I got it.
