Does anyone have a Class-10 MicroSDHC card running on their Atrix? If so, how's it performing? Thanks.
Ya I want to know this too has someone tried different classes?

i have class 4, 6, and 10 and honestly i cannot tell the difference under normal use. The only reason I got class 6 then upgraded to class 10 was for apps2sd on my nexus. I havnet done any formal tests, but from practical, every day use, no difference.
I do transfer files a lot from pc to phone so of course class 10 transfers them quicker. But normally you are not running many things off of SD, maybe music, which class 2 or 4 is good enough for.

I am still on the good old 4 GB card I bought a couple years ago. Fares pretty good for all day-to-day activities.
I just put in a class 6 16GB and I don't notice that big of a difference. I don't think you'd really notice a difference unless you were looking hard.
The higher the class of card, the faster the read/write speeds are. Things is, you will only see these speeds if you are transferring big files. If you are just putting MP3's and small videos on the card, you won't see much of a difference. Sequential Write speeds are significantly faster than Random Write speeds, but Sequential Read speeds vs Random Read speeds, there is not much difference.

Have you tried the Class-10 card in the Atrix? If so, which model/size is it? Thx.
Everyone: Thanks for your inputs!
Class Speed rating ONLY applies to WRITE speeds - has nothing to do with read speeds. Primarily designated for camcorders and other devices that need guaranteed minimum speed for writing data.
The camcorder on the phone doesn't require a specific card class, so spending money on higher speed cards is not a great idea. If you are copying movies from pc to sd regularly then it will save you a bit of time - that is all.
http://www.sdcard.org/developers/tech/speed_class/ and wikipedia explain SD speed pretty simply.
I ordered a 32GB Lexar Class 10 microSDHC. Should be getting it today so I'll post my findings. Planning on dumping all my music and maybe a few videos.

Excellent! I'll be picking one up. Thx.
I bought the Lexmar 32gig class 10. I don't see a huge difference unless I'm loading up the card with a lot of files at once.
Yes its as fast as the Patriot from all the specs I've seen but unless you can truly afford the minor difference, just get a lower class.

Saw a post FROM MOTO on the moto forums that says the Atrix can make use of the extra speed up to Class10.
FWIW.
My Kingston class 10 32GB card does not play nice with webtop2sd. However, I can format it with the system. I have not tried to write files to it but writing fat32 filesystems works for sure. It seems as if I can read from the card too. I see the folder created during the fat32 partition creation.
The issue I seem to have is that it cannot create extfs filesystems on the card using the phone. I can use gparted to make the filesystem, but then webtop2sd cannot read it.
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

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.
hello i just got an amaze and with its camera and video quality i think i need a better sd card as my current one is class 2. any recommendations and letting me me know what the phone can handle without paying for more than i need would be greatly appreciated.
thanks very much
The Amaze can handle a class 10 memory card. This would be preferred as it has the fastest read and write speed that I know of. I am currently using a 16GB class 6 SanDisk and it works really well.
Hope this is helpful. Or maybe someone else can give you more info.

Confused
My Amaze is on it's way to my door this Wednesday, and I too am on the hunt for a good class 10 micro SD card. I had a Patriot 32 GB ordered from Amazon (it had 4+ stars), but then I started reading specific user ratings. It almost looks as though there is a problem with quality/consistency with many of the 32GB class 10s. The Patriot, and several others, had quite a few recent users complain that their class 10 doesn't run any faster then their old class 2 or 4. (The complaints I tried to focused on are from users who had run speed tests and didn't just provide seat-of-the-pants analysis.) Admittedly, I was going for as cheap as I could (the Patriot was only $47), but I looked at several others and they had spotty speed comments as well.
Does anyone have specific knowledge or insight on this? Is it an issue with lower cost manufacturers whereby one card is great but the next can be dreadful. Is it the nature of the beast?
I appreciate your comments.
A class 10 card isn't the way to go with smartphones. Best to get a class 4.

UHS-1 Cards
I just read where UHS-1 class microSD's "were made for mobile devices". Something about being specifically designed to work with those operating systems. Anyone have experience with any of those? They're awfully expensive.
If you uses a class 2 SD card with a capacity of less than 16Gb and mostly uses it to transfer small files between your phone and PC - that would be sufficiency enough.
If you intend to use a bigger card, say, 32Gb or 64Gb and you are doing a lot of transferring MP3, movies, pictures ect ... especially if moving BIG files, say, more than 1 Gb each (e.g a full MP4 movie may take up to almost 2Gb)
OR
You are frequently backup your SDCard contains and moving them between PC and phone. You will appreciates the higher speed/class of your SDCard. Higher class means higher speed in reading and writting hence saving you a lot of time.
You will not notice much differences between a class 2 and a class 10 card when using it inside your phone though.
An SDCard speeding test's result will be differ from devices and that's exactly manufacturer's stated on their package/info, but, basically you got what you paid for. As we all know, Sandisk is the most expensive card out there and there is a reason for it, just do a little research and you'll know why. Sandisk classed their card at the minimum speed that their cards are capable of, whereas other manufacturer tend to class their card at the average speed that their cards capable of. Meaning a classs 10 Samsung/PNY/Patriot card may not capable of reaching the claimed speed (because, well, results are varies on devices) and the result maybe a little lower than claimed (I've tried Samsung class 10 and PNY class 10 test and the result is somewhere more or less than 9Gb/s writting).
Anyway, a class 2 16Gb Sandisk card is good enough for an average user whereas a higher class/capacity card will increase performances for those who demand more for their task/hobbies/usage
I would agree with the post above, right on the spot. I had a 8 gb class 4, 16 gb class 4, and now 32gb class 10. Did not visibly notice speed in my phone but did notice it when transferring files. You will only benefit when transferring larger files like 1 gb or more.
I only transfer my recorded videos, pictures, mp3 and that's it. I think i once transferred a movie or two.
What would have taken me 1 hr on 16 gb class 4 took me 20 - 30 min on my patriot 32 gb class 10. No problems on it since nov so far.

anything over class 4 sacrafices random read/write speeds...meaning, just to write faster the data is more fragmented. Over time, the speed becomes slower and the table used to keep track of data must access parts of the fragments that are free...this reduces performance in higher class cards...if you look at Sandisk they their class two performs way above the minimum write speed, almost double...I always buy sandisk...nothing else...their quality is unmatched...they are the pioneers...A class 4 or class 6 sandisk would outperform many of the class 10's that people are buying right now.
Sometimes as Binary's card has, they lose integrity because of this reason...the index becomes messed up and the data becomes lost eaiser in higher class SD cards and lower quality SD cards...I believe Sandisk tries to minimize this even in their higher speed cards...

If you guys take a look at the bitrate of the 1080p video and also add the audio bit rate it doesn't even come close to being 2 MB/s write speed which is a class 2 SD card...the highest bitrate for video I got was 11182 (kilobits per second) = 1.36499023 megabytes per second...add the 127kbps of sound and you barely have 1.4 MB/s write speed needed for the HD video recorded by our amaze...hope this clears things up.
Sorry this is a bit of a n00b question, but do SD card speeds actually effect the Transformer Prime? As in can it handle class 10, or does say class 4 already reach it's read/write limit?
The reason I'm asking is because I have a spare class 2 16GB micro SD card and want to use it for ROM storage - trying to figure out whether I need to grab a class 10 card instead or not. Cheers
The "class" is all about write speed, and specifically about "burst" write speed.
What that means is that "burst" writes happen when you write a huge amount of data in one "shot" (e.g. pics or vids).
Generally, lower class cards trade off "burst" write speed for random access speed. IOW, they have a lower "burst" write speed, but do better for random access writes.
Also generally, every card regardless of "class", will provide the same read speeds.
So, determine how you expect to use your card.
Going to write large amounts of data to it regularly? Get a class 10.
Going to write infrequently (especially small data)? Get a class 4-6.
P.S. cameras and video recorders *need* high burst write performance, and since the nature of that data is huge, small random-ish writes never happen.

Give it a shot. It'll probably be fine if all you're doing is reading the data off the card (it'll be slow writing the stuff to it initially tho).
Could also run crystalDiskMark on it via a PC and usb adapter.
Record a video in the highest quality. When you play back the video, if it does not stutter/skip, then it is fast enough for anything you will use it for.
As for whether it will be good enough for ROMs...try using it for the game Castlevania Portrait of Ruins and if the game doesn't freeze it is fast enough for any game. Most likely all ROMs will work though... Just test it and see before buying one.

class 10 is NOT best for all uses. In fact it can be 20-50 times slower than a class 4 for random access writes.
class 10 and class 4 are going to be nearly equivalent for any reading from the card (sequential and random).

I also have a 32gb class 4 (SanDisk). I haven't noticed any lag when picture taking or video recording.
I was looking up what kind of MicroSD to get my Amaze about a month ago and decided to get this one. Here are some things I picked up while doing the research.
1. Small read/writes usually takes place on the SD cards. Getting a class 10 with good write speeds for large files doesn't mean good speeds with small files.
2. SanDisk is a good brand. Mine is advertised as a class 4 but performs at class 6.
3. If you're looking at the Patriot class 10 microSD, I recommend that you stay away from it. People have been reporting errors with that card on Android devices. Patriot said that they've fixed the issue, but there are still a lot of bad cards floating around. You never know what you get.
4. If you do go with SanDisk, get it from a reputable dealer (not eBay). There are tons of SanDisk counterfeits.
Thanks so far guys - exactly the input and information I was seeking.
I have a 8g Class 6 from my G2, and a 4g Class 10 I paid $6 for to test out - both by Transcend off newegg.
Will get something with more capacity soon, and was wondering which direction to head.
I just got a patriot 16gb class 10 about a week or two ago from newegg for $10 ($20 with a $10 rebate) and it's awesome. I mostly notice it when transferring files (videos and music) between my phone and laptop. I had a 16gb class 6 ADATA before this one, but it was only 12gb cuz I originally used it with my G1 and had it partitioned.
My wifi downloads have been quicker lately, but I'm sure that's just coincidence. Anyways, good luck!

Higher classes are more prone to errors. With the bitrate phone records hd. A class 2 is way more than enough. Go with a class 4 SanDisk. Higher classes have better sequential good for recording movies etc. Lower classes have better random read right and less prone to long term damage. The higher class you go the more risk you'll have of getting corrupt data etc. The only benefit of higher class is better sequential write speeds. ALWAYS GO with sandisk

If I had known this sooner, I wouldn't have invested in a 32GB Class 10 disk (not sandisk). So far, I've had it crash twice, and had to reformat every time. It's rather annoying and you do lose all your data; so for those out there still considering it, please add this to your factors of consideration.

Always buy sandisk. I have not heard of any sandisk going bad but heard of all other brands going corrupt over and over. I don't believe sandisk has a class 10 or class 8. They always stick to stability and quality and is worth the price. Besides a class 4 sandisk usually outperforms a class 6 or 8 of other brands. Search for my posts regarding memory topics in accessories I talk about sequential read write and random read write and how the bit rate our phone records video in HD is waaaay below even a class 2. a good balance of sequential read write (long files such as videos or movies) and random read write (gigs of small files) is either a class 4 or class 6 if i was going to go allout I would get the new 64gig card made by sandisk for mobile phones. I think its a class 6

I have SanDisk 16GB Class 2, I bought a class 10 and its actually slower than my Class 2. Plus yes, it's more prone to error. My previous android phone would freeze up because of the class 10. Moral of story: SanDisk has great speeds even on class 2

I had to send my 32gb class 10 Sandisk in to get replaced because of data corrpution. I agree though, Sandisk is great.

sandisk doesn't make class 10's or 8's, but It could be imported or something or maybe even a knockoff...the only way to make sure you have a sandisk is to call them and ask if they actually sell class 10, to my knoweldge the fastest microsd they sell is a class 6. can you point me to their webiste or somewhere, I am very interested. they do sell class 10 SD but not micro sd. I am very curious where you got this and how sandisk is actually replacing this...I have looked all over for a class 10 micro sd.
you can buy it at newegg: for 120 http://www.newegg.com/Product/Product.aspx?Item=N82E16820171571
or on their webiste for double the price lol: http://www.sandisk.com/products/mobile1-memory-products/sandisk-ultra-microsdxc-card
don't forget to increase your read ahead cache for the sd interface too. 2048K should be the optimal size.
