I am looking to buy a MicroSD card - 64Gb or 128Gb (if the price is right) and am looking for recommendations. I had purchased a cheap, generic 64Gb card., which worked fine out of box. Within a month it began to have errors and finally failed.
My goal is to use this as media storage - books and comics mostly. So speed is not an essential requirement.
Anyone have any suggestions?
I've been using this Samsung Evo Class 64GB Micro SDXC Card since the tablet was released. It seems to have decent speed and I haven't had any problems with it yet. There's also the Pro version for an extra $20 that apparently does 90 MB/s.

Thanks, @MidgetMob, that seems to be the way to go. Grateful for your advice.
Just ordered the 64gb Evo Pro.

By and far, the 64GB G.SKILL microSD is one of the best out there, with amazing speeds, a stellar lifetime warranty, and a ridiculously low price ($24 for the next 72 Hours). You will never have to worry about your card failing since it will be replaced even if it fails five years from now. And it absolutely blows the EVO out of the water in terms of speed. Testing with A1 SD Bench on my Shield Tablet, I'm getting 72.00MB/s Read & 38.64MB/s Write with mine. I store almost all the significantly large apps on the microSD.

That's a nice price for 64GB. As for the warranty, the Evo is 5 years. Of course it's not as good as a lifetime warranty, however 5 years isn't bad either imo.
Reads and writes are quite nice, but how are the IOPS?
I did pick up and have been using a Samsung and it has worked fine. But at that price, I think that I will grab a G.Skill as well. (Can't have too much tech!)
Thanks, everyone!

Isn't MB/s to IOPS a straight conversion? Not sure about 4K Read/Writes since A1 doesn't include it in testing, and not sure what utility is best for testing on Ubuntu. And not sure if the card reader would provide reliable results given its age.
I'm testing copying over files to test write speeds. I copied over 3.92GB of files (4,214,000 Bytes) in 284 seconds from the internal storage to the G.SKILL (AVG: 14.15MB/s). There were probably slight lapses due to copying multiple files, however. Tried copying a single 429MB file (450,687,000 Bytes), and it took 19 seconds (AVG: 22.6MB/s).

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...
I am going to buy the 32 gb Prime (with keyboard) and have been researching memory card options. I am leaning towards the following:
1. Lexar High Speed microsd 32gb Class 10 (for the device)
2. Sandisk Extreme SDHC 32gb class 10 (for the docking station)
I will use this to watch movies, play music, surf the web, take notes, use apps, and play emulators.
My only concern is I've heard the class 10's have trouble with speeds on smaller files/apps/programs. Will that be an issue? Or will these two cards be a good setup?
Pretty much everything will be "slow" on working with smaller files / programs due to file system overhead.
Doesn't matter if it's a class 2/4/10/1,000.

I've read similar things as well. You will truly be fine if you just get a Class 4 and save the money.

with smaller files (a few data blocks in size) you have as many writes to the file system management space as you do data block writes.
with large files there are much fewer writes proportionately which is why large files have higher throughput.

I went with a 32gb class 10 pny micro sd from newegg. It was 47.99 and I finally tested it last week. Wrote video/music files at 11.5-12mb/sec. Some of the other class 10s had reviews claiming they only wrote at class 4 speeds. I can't stand how slow my class 4 16gb in my phone us...
Hey cyi1 is there a chance you would mind testing the write speed using your phones sd card too just to get a view of the speed difference from class 10-4?
Thanks in advance if you can. I'm sitting here trying to decide whether I get the 32gb class 4 or the 16gb class 10 as they are about the same respective price here.

I second that, would like to know this aswell. please let us know.
You might want to give this a read.
I'd also suggest getting SD cards from a source with a good exchange policy. The speeds can fluctuate wildly within a class and even from idenetical cards from the same manufacturer.
So, what ever cards you get, test them and if not-acceptable, exchange them.
I stated this in the "Ultimate Accessory" thread. But I'm going to say it here to.
Don't buy the Patriot MicroSD 32GB Class 10. It's awful and I'm not the only one stating this. It used to be $100+ (I bought it when it first came out), but now it's like $40 because people realized how crappy they are. Speed throughput was never the problem, but they randomly corrupt and when it DOES happen, it's bad. Mine corrupted on me 3 times in only a few months. Each time I was lucky to have had a backup (Ti Media Sync) and managed to save just about everything. The first time I lost a lot of pictures that hadn't backed up yet.
Anyway, the corruption doesn't come from using USB or anything. Everytime mine randomly corrupted, I was using it away from a computer or charger. First time I was watching a video off the card (admittedly porn) and the second time I was taking a picture. Third time I don't know because the phone was in my pocket in standby and when I pulled my phone out to show someone a pic from the phone it wasn't there, along with the rest of the stuff that was on the SD. Oh, and the first time this happened was on my Nexus One, not my Sensation.
Anyway, I replaced it with the Samsung 32GB Class 10 (bought it for just over $80) and it's been rock solid so far (2 months in). Speeds are pretty much identical to the Patriots. I use "Boot Manager" and dual boot a couple different ROMs off it, and they all fly.
Just wanted to give you guys a heads up.
I went "cheap" on a class 4 Transcend 32GB for both my photon and my upcoming Transformer Prime.
In actual copies, I was seeing in the 6-7 MB range so I won't complain.
I purchased the ADATA 32GB Class 10 from NewEgg and it works wonderfully. I haven't done any testing beyond copying 4GB of video files to it, which copied at a rock solid 17MB/s! I'm impressed needless to say.

Could you run a crystalmark benchmark on your card(s).
If the transcend random 4k R/W speeds are decent, that may be the ticket for me.
Thanks
curreyr:
i can, but I won't get to this until Sunday when i get home.
6mb/second was not on random writes, it was on bulk copies of mp3 files for the phone
Sent from my MB855 using Tapatalk
no problem, and no real hurry (since like others in the holding pattern to actually get a prime).
My wife's xmas gift of a new camera is getting a SanDisk 32gb class 10 "extreme" (SDSDRX3-032G-A21) that I plan on running crystalmark tests on next week.
I might even hold off getting a micro sd until 64gb cards drop closer to $100 ... (e.g SDSDQY-064G-A11A might be killer at ~$100)

Attached are the results... It's just under 5 in sequential mode...
I was also wondering this. Will there be any difference in watching a video file (1080p) between class 4 or 10?
Large video files will be skewed towards the sequential mode -- which tested @ 20MB per second. That's 160Mbits / second.
In theory, this class 4 card could playback a maximum bit-rate blu-ray iso without a problem. Blu-ray maximum bit rate is 48 Mbits (or 6 MBytes) / second.
Regards,
Class 4 vs 10
Unless you are recording HD video to the SD card, class 10 is a BIG waste of money. The class only refers to the write speed, NOT the read speed. If you are just loading videos or music onto the SD card, then even class 2 will be fine. It may take you longer to load the original files to the card, but it is NOT going to be slower in reading the data compared to class 10.
These class ratings are really needed for HD video camcorders and high FPS (frame per second) cameras that demand high bit rate & speeds. I use a 6 for 720p video on my nikon dslr and for 4-6 fps 14 megapixel shots, but class 2/4 for my phone/tablets where it is just used to store movies, songs, pictures, etc...
I just picked up 2 Samsung class 10 32gb Sd cards from fry for $35 a piece. I think it was a wise decision and will help me out in the future. I know it's overkill but I think for that price it was worth it. So now my Prime will have 96gb of storage when I hook up my dock. That is truly overkill as well, but who knows when I might need all of it lol.
After a huge thread I read here about classes, I changed my mind and went with a class 4 for the Prime (was thinking I mist get a class 10). I picked a Transcend 32gb class 4 off of Amazon for $33 delivered.
Just came across this Amazon deal for a 32gb transcend micro sd card for $17. It's a class 10 rated at 45MB per second which is decent for our Xperia Z Ultra.

Interesting. It's "Transcend" though, and i haven't had any good experiences with them. It's really cheap though, but there's a good reason for that
Tip: Don't store important documents on it.
Before someone comes in here and says i'm full of piss, i'm not saying that it'll explode in your face or anthing like that. It might work fine for you, but i don't trust them. I've had problems with them before, and the result is inaccessible data. I would rather invest in a "slightly" more expensive card from SanDisk or Samsung. They aren't bulletproof either though, but they are more reliable.
It's definitely better than SanDisk though. I had a 64gb SanDisk Ultra which failed after a couple of months.

yeah agreed. I'm on my second 64Gb ultra from SanDisk. This one seems fine though, have had it for 6 months now... They admitted via email that they had issues with the DIE process in their 64gb memory. They have rectified it and its all good now. (year right)
But nice to know they admit when there was a problem and a lifetime warantee is all good to me.
(i have 4 3TB drives with backupdata on... so my externals can fail as long as i get a new one for free)
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.

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.
Hey all. I know there are threads about the "best" microSD cards for the Shield Tablet here, but I'm wondering what cards people have been using with adaptive storage with Nougat.
I'm current using a 128GB SanDisk Ultra ave have been having a few issues with app icons not losing at boot (apps are on sd card) and some games lag a bit (BlazBlue RR - Real Action Game comes to mind). If I can find a better card for a good price, I might spend a day factory resetting and setting up the tablet again.
A SanDisk Ultra should have pretty legit 4k random speeds/IOPS.
The only other thing that comes to mind would be a high end Samsung. I think Amazons EVO select is the same card as a EVO plus if you want to save a couple bucks.
There is the new class of micro sd cards - A1.

one vote for samsung
I just went from a pretty standard micro SD card, to the samsung evo select (amazon brand) 100MB/s (U3) for around $50, 128 gig, and my load times for games are so much faster. I researched that the important thing for games/adaptable storage is the random I/O (read/write) times and samsung scored pretty high. But I play mostly rpg's so not sure if it lags, but overall I'd say it's close to internal storage speeds, maybe a little slower
As I said select is the same as plus, you bought one of the fastest card you can buy without getting into stupid expensive territory.
