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 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.

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.

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.

Does it support Sandisk Ultra II, or SDHC and is that faster than class 6?
edit: is this okay?
http://www.play.com/Electronics/Ele...com-8GB-SDHC-Class-6-Memory-Card/Product.html
SDHC refers to an extension to the basic SD specification, allowing higher capacities. Hero supports SDHC upto at least 32GB, going on what I've read. I have an 8GB class 6 card.
Ultra xxx this & that is marketing bull with no standardised meaning in respect of performance. From what I can find via google, the Sandisk Ultra II is either class 2 or 4 (or possibly either depending on exactly which card you have).
The class system is a standardised classification of read/write speeds. Always check a card's class.
Is that card (Sandisk) ok? Depends what you want it for. If you intend to install apps to your card via, say, A2SD, I'd say no. Always get a class 6 for this, but it's a matter of personal choice. The standard doesn't imply this but collective empirical evidence also suggests higher class cards tend to be more reliable.
As to the linked card on play.com, it looks ok. Even the reviews seem reasonable, as long as you aren't inflicted with a broken lock tab a few earlier customers report.
TBH as long as you stick with 8GB class 6, as of the current date, you're at the sweet point for capacity-&-performance : price ratio. I bought one recently - think it was Transcend & about the same price.
OK, I think I'll buy that then. The only reason I want it is because at the moment videos always lag on my 2GB class 2 that came with it.
Thanks.
Micro SDHC
HTC Hero supports Micro SD HC and not the standard SD card. So check that before you buy. Im using Transcend 8GB Micro SDHC Class 6 Ultra. Works like breeze.. Also check 16 GB ones coz the price must hv come down.
Oh, so sorry - I didn't notice the card he linked to was not a Micro SD
Hell, that's the second time I've done that - I actually ordered the wrong size on one occasion. I hope this doesn't cost the OP. Even if ordered, they should take a return within 7 days, by law (in the UK, at any rate).
[Edit:] This is an ok deal.
As long as the micro as is class 4 or better then you should be ok with what ever you buy but give eBay a miss a lot of faked memory card and memory stick sizes comming from places like China and the like

Hahahaha. Thats too funny. Lets just hope he doesn't tear it open as soon as its delivered, no chance of a return then.
Anyway,... I found two good prices,...
Samsung 8GB Micro SD Memory Card - £13.49
Its only a class 4, but speeds in the comments are ok:
Speed (read) 15MB/sec
Speed (write) 6 ~ 7MB/sec
And doesn't this sound interesting,... "Features:- Waterproof - Innovative epoxy moulding compound tech helps over 24 hours in sea water- Shock proof - Survives high pressure, including the crush of a 1.6ton automobile- Magnet-proof - Resists over 13 times the magnetic force of home theater speakers- Elegant Package- Content Protection- Faster Performance"
The 2nd one is what CAULI had found, only slightly cheaper,...
Transcend 8 GB Class 6 microSDHC Flash Memory Card with adapter - £13.99
One customer states "I was getting write speeds of over 6MB I think the fastest was something like 6.70MB per second!"
BUT
Another says "Write speed with this card is the slowest of the lot, barely creeping above 5.3MB/sec"
Hmmmmm,....
Any more advice anyone?
I recently purchased the Samsung 8GB Micro SD class 6 Memory Card from play.com for use in my Hero and it works great with Apps2SD
Thanks for the tips everyone
There's always ebay... I got my 8gb on there for £6 inc. p+p, you can never beat an ebay deal...
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

am using class 6 works fine.
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,
Al
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.
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 use the 16gb of this and it works great. I did hear more than once that even a good 32 gb can be a problem.
My pny class 10 32gb is still rockin with not a single error

The other 2 were damaged by my G2x .... I just got my Amaze. And the thing is.... is that I make sure I put it on "Charge Only" when I wanna take the phone from the usb cord..... try to prevent crap like this from happening!!!!!
I am usually so careful!
This SD card stopped working when I went into my Gallery!
go to newegg.com they usually have pretty good deals. i bought my 8gb card and another 4g card for my car, almost 2 years ago and both cards are still working.

Is it formatted to a FAT32? That will probably save you from most headaches. I've had my 16g for almost 2yrs with no probs. I save tons of crap on mine. Movies, music, roms, apps...etc I haven't had a problem as of yet.

did any of them happen to be sandisks, directly from sandisk website? I have NEVER HAD ANY PROBLEMS WITH sandisk, IT MUST BE authentic though. Used a micro sd card for the past 3 years, still works.
depending on what you use your micro sd for it depends on what class you should get, a higher class is not always better for your purpose. A higher class has better sequantial read write, while a lower class has a better read write. If you transfering files all the time, I'll stick to class 2 or max 4. If you're trying to shoot movies more of the time get a higher class. there's been a topic on classes of microSD, honestly you don't need anything more than a class 2, it has plenty more write speed than is used by our phone to shoot HD video.
ALSO lower classes are WAAAAAAAAAAAAAY less prone to get corrupt. keep that in mind next time.
SanDisk is ALL I will EVER buy.
I've git a 32GB class4 that I bought before realizing I need a class6 for 1080p video recording almface: but I've had no issues. I've also had an 8gb class 2 that's NEVER had issues (other than writing really slow) and I've had it for yrs now

I have an ADATA 32GB card that I bought from Newegg back in September that has worked great for me. I used it in my HD2, and now in my Amaze. It is a class 4 card, but it has worked great for even 1080p recording on my Amaze. I'll test the speeds of the card and give the results later.
I picked up a class 10 Kingston 16gb on sale about 2 years ago and it's been working great. Loaded with movies, music, games, roms, etc... Use it everyday.

I had an 8GB which was Class 4..... and it was NOT SanDisk. I shoot a lot of high quality pictures and HD Vids.... That's mostly what I need my SD card for.... that and keeping my Rom downloads... I am so mad!
Doesn't lower class mean it will take a phone forever to read a 16gb class 2????

I don't know if it was Fat32... I don't believe so.... but thanks for the heads up, will keep it mind!
If you use swap it will kill your sd card pretty fast too....

I have my original 8gb SanDisk that came with my Evo 4G on release date and it still works perfectly. I've always stuck with SanDisk because they last.
Must be bad luck. I have a 16gb class 6 that I use in this phone and my last phone. So close to two years old now.
I have an Adata 16 gig class 10 SD card that eventually went bad on me. They are supposed to have a lifetime warranty so I'll see if I try that.
That microsd gave tons of headaches. My Droid 2 would start acting funny once it went bad. It would freeze, pics would show up sometimes and sometimes now. Lots of forcecloses and my computer would read and read it. I pretty much had to reformat it to get it working again but a few days later the problems would pop up.
I went ahead and bought a samsung 32 gig class 10 once I got my Amaze. So far so good this thing is even supposed to be water proof with a 5 year warranty. It was around $37 from Fry's.
I have a 16gb card for 8 bucks from ebay that I bought about 2 year ago. Works great.

While looking... I found myself proven to be corrected.

Hi all,
I have the 10.1 2014 tab pro and I want to get a new SD card. I know from my brief reading through these forums that not all SD cards will work and I dont know enough to really understand what is what (like what does "SDHC Tf Class 10" mean?). If anyone knows what it is that I need to look for before buying one so that it will work fine with my tablet please post here.
ps I am using these primarily to store books and documents, not videos or games or anything that really takes a massive workload or speed requirement.
pps Im not sure if this matters, but I am running stock unrooted
TIA
Most any newly purchased MicroSD card should do. What did you read won't work? Below Class 10 cards might not work for some high speed functions (like video), but I believe all should work for casual use like you describe.
SDHC versus SDXC mainly refers to the capacity of the card, which you are probably going to be looking at separately (in GB) anyway, so it really doesn't matter. Basically, the original SD standard (also called SDSC) was limited to 2 (4?) GB. SDHC increased the capacity up to 32 GB, and anything higher than that is SDXC by definition. There are some other minor differences, but probably nothing you really need to worry much about.
Class (8, 10, etc.) refers to the read/write speed; but you may also see a UHS speed classification (U1, U3) also. Even though you are not talking about high speed demand tasks, I'd still tend toward Class 10 or U1 cards. Just in case you change your mind about what you want to save to the card; and many cards meet Class 10 or U1, anyway. For the few cards that you can find with lower speed class, you might save $10, so its probably not even worth it to consider lower speed class cards.
The following Wiki articles goes into a lot more detail about the specs: http://en.wikipedia.org/wiki/Secure_Digital
Out of all this, I'd be more worried about brand, or getting a counterfeit product. Some cheap or off-brand cards seem to fail more frequently than the big names. Folks all have their favorites, and may argue that you are just paying more for the brand. But I've bought several Sandisk cards, and never had any issues (and heard similar from other users on XDA).
I'd also stick to a reputable seller (Newegg, Amazon, etc.) as places like eBay are awash with counterfeit SD cards. Its so easy to relabel a card as a higher capacity (i. e. take a 32 GB card and label it as 128 GB, etc.) and even spoof the device to read it as the "fake" capacity, than charge much more $$$.
I am using one of these on my TabPRO:
http://www.amazon.co.uk/Samsung-MicroSDHC-Memory-without-adapter/dp/B00AYC6V2U
Works fine on all my Android devices.
And to really leverage it outside of Google Apps and pre-installed items you need to root and enable write to the SD card, unfortunately. (Unless I'm missing something.)
Thanks, I really appreciate that info on what all those terms mean. However, right now I am using a 32gb Sandisk ultra, and my data keeps getting corrupted, apps cant find it, showing up empty on every file explorer I try.... Therefore I thought since Sandisk is legit (I bought it at costco so its real Sandisk) I figured there must be some issue with the type of card.

I had similar issues with a genuine SanDisk card in my S3 (couldn't access it in recovery either), just showed a bunch random characters instead of file names etc), swapped it to a different brand (I got a genuine Sammy one because it was a bargain at the time) and that solved the problem....
