SanDisk Mobile Ultra MicroSDHC 16GB SDSDQY-016G-E11M
I had a new Class 4 16GB Micro SD Card delivered yesterday after one of my cards failed.
Speed was markebly improved over the old Class 2 cards I have. Data transfer was particularly impressive!
The card is a little pricey £££ and I could have replaced the faulty card with another cheaper Class 2 but thought I'd give the "Ultra" card from Scandisk a go.
I watch a lot of video (on the train on the way into work in London - Heroes, Battlestar Callactica etc !!!) and speed is important - especially for standard DivX with no additional compression! Any lag I had previously has now gone - Very impressed....
I ordered the card from Amazon - link below - and although it states 3-4 days for delivery it arrived next day.....
Here>>> Amazon.co.uk
ScanDisk Official details can be found >>HERE<<

Are you getting any skipping/jumping/pausing of music with this card? I would be interested to hear especially with your rom as I did get such problems with my class 2 16gb card and same rom (Dutty 2.3). I've just flashed my old Polaris to 3LIT3 VI Suite and am now getting the problems on this device which I never used to. Hence my theory about the card being the cause of the problem.
Will be interested to hear.
Thank you.
Wow, that is certainly impressive. I presume you're using CorePlayer to play the vids? And no lag at all? Awesome.
PS: To Galactica... best ship in the Fleet.
I've had the card for a few days mow and have just returned from London and can confirm that the video playback is greatly improved. I'm using CorePlayer - I used to get some ghosting (phasing) and the odd skip but now its very smooth indeed.
custardo01 With regard to music - I have never had an issue playing music so cant comment on why your experiencing a problem - I'd recommend copying an audio file onto the main solid state drive (device) and play from there to confirm its a problem with the card before purchasing a new one though?
Arthenik .....Galactica - Absolutely - watched the 2 hour final episode yesterday (on the HD) fantastic but such a shame its over!!!!
.
Well, I guess I'll have to get one too. I'm really impressed by your reactions.
Regarding Galactica, I watched the finale on air and then subsequently at a local Frak Party. Both times were frakkin' awesome. And yeah, I'll really miss the show a lot.
bench of new CLASS 4 SanDisk Mobile Ultra MicroSDHC 16GB SDSDQY-016G-E11M
Hello,
Could you bench the read/write speed of your card with a tools like SKTOOLS
It would help me a lot to make my choice.
Thanks

Palmde - I'll try to find some time this weekend to benchmark but as per previous posts I am very impressed - especially with viewing uncompressed video!
.
Thank's a lot for your help Blob8me.
I own already a SanDisk Mobile Ultra MicroSDHC 8GB and i am very hapy about it: I can watch most of my movies on my HD, without to re-encode them.
I hope that the 16GB version will be at least as good.
So I am waiting your results.
£38.99 including delivery here. They say it's class 4 ?
Just asking but where the hell do you need class 4 microsdhc?
class 4 means it writes 4mb/sec VIDEO to same place in card, so datastream stays healthy for camera usage for example 1080p HD CAMERA.
It doesnt mean it only works that slow. Our HD cannot even match those speed anywhere near. And second these phones do not use that kind of file management to save continuous file stream.
For example I have kingston class 2 and it writes 12mb/sec when using cardreader on PC.
Or example 2 so people really understands. There is SDHC card from sandisk which is Extreme III 30mb/s edition. That is only class 6 card. And it still writes as fast as 30mb/sec. Ive tested this and can confirm since I have those on my DSLR camera.
So question is why do you pay MORE for NOTHING?
Dont read class number, read what it writes and reads per second its what you want to know.
Edit: Ofcourse bigger class means it can be better but class number doesnt tell its real speed. since class number is for continuous data (video writing)
So I ended up ordered a 32gb micro SD card off amazon without realizing the class until yesterday and it was too late to ship it. So I come here asking should this be okay for my TF?
I know the speeds will be slow but if that's all it is I can deal with it. My main concern is I have a lot of 720p & 1080p videos and I don't want them to lag. Will there be any lag when using this card, or should I just go ahead and return it?
Let me know if this has been asked or is in the wrong section. Thanks
That class doesnt have anything to do with read speed, only write speed. So a class two *should* be slower to write videos to it than a class four but read wise both should be much faster. Of course the actual speeds can vary by maker.
So, yes, a class two will be fine for playing HD video.
I've been using good quality (Sandisk) microSD cards Android devices for a long time now and *never* had an issue with them.
Remember the following:
1. The class of an SD card doesn't tell you how fast it is - it only really tells you how slow it isn't!
2. It only tells you the minimum sustained write speed in optimal conditions (i.e. unfragmented), and nothing about read speeds at all.
3. Good quality lower "class" cards can often exceed the class minimums for higher classes anyway. For example, I've several 16gb Class 2 Sandisk microSDs and in my testing can regularly achieve write speeds of 7MB/s with all of them.
Regards,
Dave
Cool, thanks a lot! If I ever get tired of the write speed I'll just grab another one later on down the line. Thanks again
Just to add my voice in agreement with the above posts:
Class 2 Sandisk cards are fine, even for 1080p files.
There is a lot of misinformation out there regarding Class speeds on microSD cards.
I've watched a 1080p high profile MKV with a video bitrate of 9500kbps on my Galaxy SII on a Class 2 card, no problems.
Heres my video showing exactly that:
Yep I've used C2 Sandisk and PNY cards without any problems.
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

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.
I'm thinking of buying another micro SD card for my Razr. Current one is 4GB, Class 6 from Transcend. Thinking of getting a 8/16GB one, class 6 and above. Anyone has any recommendations on which SD card to get?
Sandisk? Most devices come with a Sandisk card so I would imagine they are good cards.

I have two 32GB class 10 cards (one for my phone, one for my camera). This link helps with deciding which class will perform best for your needs. One is a PNY and one a Transcend - both work well and don't lag when recording HD movies or pics.
Using 32GB class 10 from Lexar. So far satisfied.

Hey guys, just a quick question. For recording 1080p videos using the phone, which class would perform well enough for a normal user?
Edit: If I do make a purchase on Amazon.com, where do I head to if I have any warranty issues?

Ah I see. Class 10 is like the highest already eh. If that's the case, I'd have to cut the capacity since I've got some budget going on.
Brand-wise, PNY Transcend Sandisk etc, which are more reliable btw?

Look at the link specs and price them out on Amazon or wherever. Maybe you'd do better not going to a 10 but happy with a 6. But given the specificity of you asking about HD recording, a 10 would be ideal. Mine were in the $38-$45 range and both have performed without problems.
I've been using Sandisk cards for the last few years. Picked up a pair of 32GB Class 6 Micro-sd cards for $20 each. My HTC Sensation had no problems recording 1080p Video on those cards.
ADATA Class 10 32GB - Best one, but maybe the more expensive too. Its up to you on how much want to spend.
Have you guys/gals notices any difference in video quality with different speed cards? Is the 1080p video on a class 6 card looking as crispy and clear as on a class 10 card?

Ummm, your video quality is going to look exactly the same on any card you use that can write the video file fast enough.

Thats what i thought, but when i play the video to my 50" tv the class 10 card video seems better quality. Is it possible is has to do with the read speed difference?
Hmm. I went to google, and I found that a few posts actually says that a Class 10 card would actually be too fast for a phone. Since the phone won't be able to handle those speeds. Any truth to that?

I'm using class 10 and have no problems at all with recording or playback. The SD Association recommendations are:
What are the applications for Speed Class?
Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording
Class 4: MEPG-2 (HDTV) video recording, digital still camera (DSC) consecutive photo shooting
Class 6: Mega-pixel DSC consecutive photo shooting, professional video camera
Class 10: Full HD video recording, HD still picture consecutive shooting
Just thought I'd report this as I've not come across any information on the subject.
This past week I replaced the stock 8GB (class 3 I think) SD Card that came preinstalled in my X2 with a 16GB class 10 SD Card. I have made no other changes or modifications. I'm running CM7 and had around 3GB's free on the 8GB Card.
I immediately noted that the couple of graphics intensive games i play (ShadowGun & Modern Combat 3) loaded nearly twice as fast and where the audio would skip at times before with a few lags here and there it doesn't now. Overall the game play is much smoother with no lags at all.
My benchmark scores in Quadrent have gone from averaging around 2850 to averaging around 3200. Smartbench 2012 has shown a consistent increase as well all but far less. Overall the phone seriously seems snapper, smoother.
And lastly i would like to say that the graphics appear to me to be rendering better particularly as regards curved lines...and yes I know this is a very unscientific observation on my part.
In closing i know most of us spend a great deal of time tweaking and testing different mods trying to squeeze even a few percentage points of extra performance out of our phones. Well here seems to be a way to get an extra 10-15% or so by simply upgrading the SD Card.
Oh...the card I got is made by Team Group, Inc purchased from Newegg for under 20 bucks, free shipping.

I upgraded to 32gb class10 myself. Was warned that it was not supported and would give me errors. So far the only problems I have had are.
1 when using with card reader make sure it is sdhc compatible our else it will corrupt card when it can't read it.
2 when I was on CM7 using USB it gave me some errors but not sure if that was the card or CM7.
So basically when I back it up I just shut my phone off and back it up using a sdhc compatible reader.

The original SD card was class 4. Just so you know.
I too noticed a major speedup when replacing the stock 8GB Class 4 card with a 32GB Class 10 Card from Lexar. I have had no issues with the card at all except that CM7 seemed to swap the cards but did not setup the sdcard-ext properly. I have run no benchmarks but in day to day use it was an improvement. Then installing CM7 made it even better.

So does Motorola's product page:

I've always understood the x2 can support a 32GB SD card. I went with a 16GB purely for financial reasons. I put the information up regarding the performance increase of my phone simply because in all my searching the Android forums for tips to get the most out of my x2, upgrading the SD card was never mentioned. I really am blown away at the effect simply upgrading the SD card has had.

I have heard it's not the 32GB it's the class 10 that's not supported. I have not had any issues myself either except when hooking to PC but one was my USB card reader was not sdhc compatible, the other was CM7 using USB cable to transfer but have had problems with stock card also so think it's more of CM7 thing their. As far as only using it for phone have had no issues.
