Hi guys,
I'm thinking of picking up an SD card for my prime when it comes in. Does anyone have any recommendations as to which class I should get?
I'm thinking 6 or 8 minimum, esp since I will likely end up watching movies (avi, mpg, mkv) off the card. Has anyone tried doing this yet or testing which class SD cards work best?
Gracias
Transcend 16G class 10 works super fast. Love it. My only choice.
And it's not expensive in my region (TW).
I tried a class 4 on my old Advent Vega. When there was no comparion, class 4 seemed ok. But now after a class 10 card experience, I don't think I want to settle for anything less fast.
Looks like Sandisk 32GB Class 4 is what a lot of people are recommending.

Just received the SanDisk 64 GB microSD Class 6. Getting 7.3-7.5 MByte/s write speeds.
Also have a Samsung 32 GB Class 10, getting 11-12 MByte/s writes.
Write speeds returned on transferring big files (>600 MB) only.
SanDisk comes exFAT formatted so you can put files >4GB on it (very handy for those big mkvs). Samsung comes FAT32, but keeps same high write speeds when formatted exFAT. 64 GB works well with the Prime.
Any way to get rid of the SD card notification in the notifications? Been messing with it for a lil while and can't figure it out...

CrystalDiskMark is real good for testing card speed (from a PC).
After reading a HUGE thread here on XDA about all the classes and how it can vary depending on your need, I opted for a class 4. I was convinced I needed class 10, but after reading that entire huge thread I came to see that for my needs, class 4 was fine and perfect and class 10 of little actual value. So I got a very highly rated Transcend 32gb class 4 off Amazon.

From Wiki:
The Speed Class Rating is the official unit of speed measurement for SD cards. The class number guarantees a minimum write speed as a multiple of 8 Mbit/s (1 MB/s).
Classes
Class 2 - 2 MB/s
Class 4 - 4 MB/s
Class 6 - 6 MB/s
Class 10 - 10 MB/s

Basically the Class you "need" will depend on the kind of data you will store and how do you plan to use it... For storing and editing plain docs I wouldn't mind having a low class SD, but it would make it harder for your TF to write other files as HD Videos as fast as it should.

Just make sure it's a Sandisk micro SD in my opinion. Their C4 cards tend to be a lot better and more reliable than most peoples C10 cards.

Well I'm not saying I would buy one of those, the cost is prohibitive, just wondering if it was even an option.
you can get a class 10 for $40-60, so even if the Prime cannot use a class 10, why not buy it to future proof the purchase and then when something comes along that can use a class 10, you have it.
Iam looking for a well rated, 32gb class 10.
Hopefully it will support microSDXC, so when the prices of them start to come down we can extend the memory massively!
Just format the sdxc with a file system the Prime understands. sdxc is just using exFAT. I'd format it with FAT32 or NTFS (if the Prime supports it).

The SDXC card was tested on the TF101. No problems there. I'm pretty sure it will work on the Prime as well.

Nobody knows if SDXC will really work but it's almost sure it will.
And why the heck do you guys think the Prime won't support class 10 cards?! Even my old Desire HD supports them with no problems
Wow. That article is full of fail. Its said that the TFP had a 5 Mega pixel camera. I wouldn't trust much in it.

From what I understand, SDXC just added the exFAT requirement for the for it to be SDXC. From what I originally read awhile ago, sdhc hardware will support 2TB cards. There are a lot of people using the 64GB MicroSDXC and 128GB SDXC in devices at said that they only support SDHC cards. They just formatted them to a file system the device can understand.
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.
More room for stuff is always better.

Just to add, nt only supports up to 32 gb sd.
And, you would want a card with a higher class (i.e. class 10) for viewing movies, listening to high quality music, or running an os from your sd card.

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 purchased it about a week after I got my NT. So I've had it since the beginning of January. Not that long to really determine the longevity of it. Pretty good reviews overall on Amazon.
Do you know of any good apps to test out the card? I could run them and get you the results.

Write: 4.7MB/s

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.

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

Go for a 32 GB one if you think you'll be able to utilise the space. If you pick a class 6 or 10 card you really shouldn't have any speed problems. Obviously a higher class card is faster - class 10 FTW!

Well 16Gb or 32GB is based on your requirements
My suggestion would be 16GBclass 4 or 16GBclass 6

for me
Class are based on their speeds
Class2 -->2Mbs
Class4 -->4Mbs
Class6 -->6Mbs
Class8 -->8Mbs
Class10 -->10Mbs

There's a thread on this subject somewhere here.
What you need to consider as well is access speed.
Higher class cards transfer faster, but to do so, data has to be accessedfirst, and that takes longer with class 10 than class 2 for example.
That means, if you are goinf to work a lot with larger files, it pays you to get a high class, if on the other hand, you are going to onstall apps to work with small files a lot, it will actually slow you down.

I've found it, anybody interested should look at the tests results

The term used to measure performance escapes me right now, but they said it was more important than just the fact it's a Class 10.
I searched the forums and can't seem to find the posts mentioning fast SD cards for the tablet, so I'm asking a direct question:
What are scientifically and objectively the fastest SD cards (at least 32GB) for the Nook Tablet?
I'm tired of waiting 7-15 seconds to turn a single page in a large PDF. I am not exaggerating.

currently i have a 32gb class 4 sandisk and i have some epub format ebooks that i am reading now with aldiko. turning pages are pretty quick. the general rule of thumb is this:
if you care about file transfer speeds as in copying/moving files from a hard drive to your sdcard, the higher the class the better.
if you care about performance as in how the files are read which in your case is what i think you want, class 4 or class 6 is the sweet spot.
Also wasn't there some issues with higher class cards and stye NT clashing? I think general consensus is that the class 4 works best the the NT.

I'm just a noob , but I think it also depends on what you're running. I dualboot and run CM9 straight off a SD card. I read sequential read/write is what essentially makes the class 4, 6, etc. But for running a ROM on it, it's all about random write. SanDisk is recommended in this case.
But by all means, check for yourself. Hope that helps.

From Wikipedia: http://en.wikipedia.org/wiki/Secure_Digital
Class 2 for SD video recording
Class 4 and 6 for HD ~ Full HD video recording,
Class 10 for Full HD video recording and HD still consecutive recording
UHS Speed Class 1 for real-time broadcasts and large-size HD videos
Our beloved Nooks can't do any of that. The general consensus is that these such devices just weren't designed to take advantage of the higher speed cards. The test results in the chart referenced earlier bares that out.

Same here. There's an old thread on XDA somewhere that tested sd cards and r/w speeds. It was SanDisk hands down, class 4, either a 4 or 8gb. It was found that for these tablets booting from the sd card, the class 4 was superior to 10's.

Either try a different file system all together, such as Ext3,or try formatting the SD card with your tablet.
