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.

Looks like it may be worth it to go straight to class 10.

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.

I could understand saying a class 10 isn't necessary, but to say it isn't the way to go, a class 4 is best doesn't make sense. Care to explain why?
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.

http://www.xda-developers.com/android/32-gb-micro-sd-analysis-speed-test/
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.
...to run optimally while recording video/taking pics?
Or can you get by with a lesser class (6) or so?
Just wondering what everyone is using and why.
I have a 32GB class 4 SanDisk and it works great.
Sent from my Energized Amaze
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

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.
What's the difference between the classes of SD cards? Which one is best for the Atrix?
Sent from my Atrix
The higher the class the better it usually is depending on who makes the sd card. Sandisk is the best in my opinion even though the class cards get very expensive for them. But each card I have bought from sandisk have never failed on me. Try googleing class card speed and their should be a few guides put out there about them. I don't know personally if the ATRIX can handle the very high classes but I could be wrong.

The answer to your first question is "SPEED" and that is it. It has nothing to do with who manufactured it (except indirectly in that lesser known mfrs may lie or exaggerate about their speed.)
In order to identify it as Class 4 or Class 10, it must have speed that fits in that classification.
Here are the basics.
Class Speed
Class 2 2 MB/s
Class 4 4 MB/s
Class 6 6 MB/s
Class 10 10 MB/s
Hope that helps.
FWIW, I am using an A-Data Class10 16GB card and it is smoking fast. No skips or pauses when playing media.

Hey I learned something today. thanks.
Sent from my ATRIX using the Premium XDA App
I am using a Transcend, class 4, 16GB card and also have no issues with skipped music, or recording/playback of videos. The only place I see a difference is with benchmarks if I drop in a class 10 from one of my other devices. Other than having higher benchmarks I see no advantage to paying the extra cash for a class 10 sdcard for the Atrix.
I copy large files often to my phone and also for when I make full SD card backups. It makes the process so much faster. Well worth the extra cash. Time is money afterall
now im wondering if my "frozen" songs its because my sd card.
i'll buy one class10 and see, my sd even show the class, should be class 1
The answers are right on. I have a 16gb class 4 and it is a lot better than the 8 gb class 2. Transferring zip files is a breeze. I am sure a higher class will be in my future.
I have a class 10 I got on sale and coming from my class 4 I could not go back. I do a lot of music transfers and the class 10 is a night and day difference

Other than read/write speeds when hooked up to a computer, is there any other benefit to getting a class 10 card? I have a 16GB class 4 card in my phone, and it works fine when it is in the phone, ie: I don't have any sort of lag when playing music stored on the sd card, etc.

Well, you need a class 6 at least for 1080p recording... Class 4 can only do 720p. And do a backup once on your class 4... Then do a backup on a class 10... You would be shocked how slow the class 4 is. Same goes for copying files

Well shoot, I didn't know that about the video recording. Looks like I am gonna have to get me a higher class card now to take advantage of the video on this thing!
Anyone here use a 32gb microSDHC in their Rezound? If so, is the performance just as good as what came with the phone? Also, any experience with Class 10 vs something slower? I'm pretty sure that would only really affect video but I assume the one they packaged with the phone was worthwhile.
Anyway, I saw Amazon has a Class 4 (slow) 32gb for $19 (http://www.amazon.com/gp/product/B0056TYX8U) and figured I might grab it so I can store more music on my phone.

i invested in a class 10 32gig'er and i would not have it anyother way...especially if you plan on using the HD Cam mod that doesnt compress pictures...absolutely beautiful pics and no lag between snapshots...as far as the video...ive recorded several 720p videos and they look pretty good as well, plus youll have hours and hours of video with even a few gigs...i have about 20gigs of music and some movies and tons of ruu and roms...with the 8gb that are left i can still record 4 hours of 720 p video...i prefer 720p to the 1080p option because 1080p records at 20 fps vs 30 fps for 720p, id much rather have smooth video...i also prefer the lower megapixel settings than the full 8 just because no ever needs to print a picture the size of a billboard...but none-the-less i couldnt imagine my rezound with out one, infact the only thing that kept me from buying a class 6 64 gig card was the difference in speed, it is so much more important than the size
I use a Class 4 32gb that came with my old Thunderbolt. Still using it with no issues whatsoever, and I play music and videos from it a lot.
I got a class 10 32GB on one of the amazon.com lightning deals one time for $31. It's blazing fast. Can't speak to slower ones. I used a class 6 16GB before that, which I loved.
To tell you the truth; I pretty much filled up my 32g. Got a 64g in it now.
I have a class 4 32gb also, haven't had any problems with it. I think the speed is about 8MB/sec IIRC.

The speed class you choose should depend on how you plan to use the storage. If you're going to be writing/reading data constantly, then you'll benefit from a proper class 10 mSDHC. If you plan on filling it up once and adding to it occasionally, then a class 4 or 6 would be fine, IMO.
I have two of these and enjoy the consistent 18MB/s read and 15MB/s write speed: http://www.newegg.com/Product/Product.aspx?Item=N82E16820211558
Does it make the phone itself faster during normal use (compared to a slower card), probably not. However, it makes transferring roms, nandroids and music/video much more bearable. In the end, it's up to you and your usage style to decide if the higher speed cards will be of benefit.
More info on the definition of SD speed class specifications can be read here: http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating
If your budget will allow, go for a class 10. Just in case you need to transfer some big file in the future.
