Guys, there are Micro SD and Micro SDHC cards. Which one of these will work in Atrix? And what class card should I get so I would not have any issues HD recording?
Thanks
I installed a Micro SDHC of 32 GB and worked fine
both will work, 4GB and above are always microSDHC.
class 6 or higher but even then some cards are faster than others. Some are optimized to deal with small files fast, while others that do well with large files, suck with small.
read reviews somewhere like newegg and take them all with a pinch of salt. Generally you get what you pay for and a company that has a warranty in your country is worth a lot if you have to return it.
What about the 8gb SD that came out the evo can u use that
Edit I looked u can nvm thanks tho

Class info...
Did the class of the sdhc card will affect performance of the Atrix... I know the higher class the best performance you have... but for the Atrix which Class do you recommand to not affect performance of the phone?
Go with a class 10, if you can afford it.
micro sd card
I am using a 32gb class 10 parrot micro sd card
The higher the class the faster the transfer rate. I get about 10-15mbs/sec transfer rate
Do keep in mind that you shouldn't be cheap by purchasing the micro sd card online for many reasons such as it can be fake, doesn't have the full potential memory, or data can be wiped once you almost exceed memory capacity, Some can also cause viruses
What class will I need for 1080p? I would rather buy a class 6(im cheap), cause a class 10 32Gb is like 100 bucks. That's 66% the cost of this phone!

I'm using a 4GB SDHC Class 2 from my old G1. I noticed when moving data from the internal 10.71GB I get at least 5-5.5 MB/s write and 10-15 MB/s read when dealing with large (350MB - 1.2GB files)
Using the 1080p Camera hack in Gingerblur 3.5, I've shot 7 sec 1080p 23.265fps video to the 4GB SDHC without issue. According to MediaInfo the Video is 11.7Mbps 1920*1088 (16:9), at 23.265 fps, AVC ([email protected])(1 Ref Frames). The 720p video it shoots is 11.8 Mbps.
Regardless of fps, the bitrate is 11.7 megabits per second which is 1.4625 megabytes per second.
So basically class 2 micro sd(hc) is good enough.

Can the G tablet handle a a SD HC card ? The user manual just makes reference to the tablet being able to accept up to a 64 GB 'SD card'. Just want to make sure that the card I purchase will be compatible with the tablet. If it can take a HC card, what class is recommended? If it isn't compatible with HC cards, then I suppose a generic 32 GB SD card will suffice.
Yes, it can handle SDHC for sure. SDXC is needed for >32GB, but I can't speak with experience on that.
Thanks for the input. Now I just need to find out what class to get.

I just joined the forum after getting my G Tablet, so this is my first post and I can't post url yet. Anyways, I've been reading up on what class card to get, and was looking at the different class ratings and found this source (warning, it is wikipedia):
go to wikipedia and type "Secure Digital"
The class rating, according to the source, states the rating is x equal to 1.2Mb/s (derived from CD-ROM speeds of old). The highest class speed I've seen is class 10. The question is, will the G Tablet benefit fom class 10 (there is a premium price tag) over a less expensive class 4 card. Here is an article I read that shows speed compared to a class 4 card with both class 10 and class 4cards in a Droid X. The Class 10 was faster, but marginally:
google "32gb micro sdhc class 10 review"
When run off a PC, there was a significant speed improvement, but not when running from a smartphone device.
So the question to ask, "Is the cost/performance of the class 10 worth it?"
From the gTablet, I would bet you will see little to no difference based on card class. For me the speed benefits increases with the size of the card. eg it isn't that big of a deal to fill a 1gb card at 2 mb/s, but it takes ~16 hours to fill a 32gb card at that speed. I would say for anything 8gb or larger, it is probably worth it to buy the faster card.
Late post to this thread, but for search purposes.......
I bought my gTab specifically to watch movies on, movies I've already ripped from my dvd collection.
I own a few 16 and 32gb microSD cards, and I have a 16/32 in class4 and a 16/32 in class 10. Watching movies from either card shows no difference at all. I've tested each microSD card I own with the same movie file and they all play perfect.
For other purposes I guess speed might make a difference. But running movies (at the settings below) makes no difference at all between the average class4 or the more costly class10.
DVDFab with a Fixed bitrate of 3000 kbpp, 128 kbit DolbyProLogic2 sound, mp4 format(h.264 video/ aac audio) with 848x480 resolution, 29.97fps, 100% volume and no deinterlacing.
With those settings my movies play flawlessly and look fantastic, on all my microSD cards no matter the "class".

You wouldn't expect their to be a difference in transfer rate for 2 reasons. First, your 3000kbps bitrate = 3Mbps = 375KBps and is well within the transfer rates of Class 4 (4MB/s), Class 6 (6MB/s) and Class 10 (10MB/s) and second, the movies don't tranfer faster because the the movie is set to play at a fixed frame rate.
You are correct that for running a movie the faster card is of no benefit but time how long it takes you to copy the movies from your PC to your card & see how much time the faster card will save you.
Strictly for the sake of knowing and answering my new curiosity about it, I'll try that this weekend. I usually just drag/drop movie files onto various folders on my pc desktop then just "right click-send to" to the microSD's(in a usb adapter) and other USB thumbdrives that are plugged into my tower....then just walk away and make dinner, play with the kids, etc....... Later on at night it's all set. For my personal usage, the class 4 cards are perfect...performance and cost.
To get the rated speed for each device class, the filesystem structures on microSD card also have to be aligned correctly. Mis-alignment has the potential to cause drastic speed reductions. Use the SD Formatter on all external SD cards.
I am getting roughly 4.9 write and 20.2 mbs read on the class 4 micro sd card that came with the phone. I got these speeds using SD Tools from the market.
What class 10 micro sd cards would you recommend? I was looking at patriot, but the read speeds reported in the amazon review are lower than what I have with the stock card.
Is the stock card just getting awesome read speeds, or is the results flawed? Anyone have experience with patriot? If not patriot, what would you recommend?
Don't really trust the results from SD tools. Seems really high when I'vetried it on this and my EVO 4G. Try Antutu benchmark. Has an SD test. Seems more realistic.

havent did any benchmarks on it though, just subjectively seems good. no stuttering in any videos thus far.

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

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.
So I'm looking to upgrade from my 4 gig Kingston microSD card to something bigger in preparation for CM7 and other things that should give the NT more capabilities in the future. I tend to use memory rather heavily: listening to high bit rate music, downloading lots of apps, and lots of games (especially RPG ROMs). So here's a couple questions I have:
At what memory range should I be looking? Is 32gb overkill?
Is there any brand that I should stay away from, or any that I should prefer?
Are the rates between a Class 4 and, say, a Class 6 SD noticeable?
What places are known to offer some good deals on SD cards?
Should I not even worry about more memory because of the NT's internal memory capacity?
Any thoughts or suggestions are appreciated.

Personally I got a sandisk 32, mainly because I am about to travel so wanted the space for movies photos etc
id get the bigger one. its better to have alotta space available, then be saying in a month "darn, not enough space for this app". better to have alot of free space then have, just a smidge too little
plus if you have alot of apps it will make your back ups larger.
a bigger card would mean your could keep a couple back ups on deck.
Get a 32Gb Sandisk class 4. I didn't get a 64Gb because its way too expensive.

I would go with the 32GB if price is not an issue.. you can never have too much room.
Make sure you buy from a reputable place.. fake cards are common on ebay and can be problematic in both performance and capacity. I usually stick with Sandisk or Kingston for brand but i'm sure there are other good ones... these are just the ones i have had success using.
I have both class 4 and class 6 cards and haven't really noticed any difference.

The class system only sets the write speed, if you look at the link I provided you will see a higher class cards is not always better for everyday use. Especially if you plan on running your os off it.

I'll probably stick to 1024KB to speed up smaller writes.
I use Transcend 16 GB Class 10 microSDHC TS16GUSDHC10 cards in all of my devices (2 android phones, Nook Tablet). Works great.
Movies can be transferred to the memory card very quickly, using the external cardreader (writing speed is about 19 MB/sec).
price is about $25 on amazon.com
I would always go with the highest amount of space 32 gb class 10. I always shop for my electronics at Newegg.

I use NT with Transcend 16GB for last 2 weeks. No problem.
Some high speeed (class 10) cards don't work with old Motorola smartphones, e.g. Milestone XT720.
