Hey guys, I ordered my 32GB Prime, super excited about it, and I want add another 32GB memory card but I don't know much about the different classes. Is there a huge difference between them? Thanks for any advice.

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.
More info here:
Wiki Article
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.
Wonder if the micro SD card slot will handle microSDXC cards? Anyone know?

Would be interesting if it did. But dang, for that much $$ you might as well buy the 64gb Prime...and then some.

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.
This article states that SDXC cards will work on the prime.

What an horrible article full of wrong facts...
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.

Hi, I am looking to purchase a memory card for my transformer and am concerned about not being able to play movies from it due to stuttering....
Has anyone tried the standard Sandisk card yet? I always use Sandisk products and know their words are always faster than what an equivilent competitor card states.
Just doesnt seem to be many 32GB options available in the UK at present.

if your looking to play high def 720p or 1080p then i'd go with class 10. class 2 will most likely lag.
I bought a Patriot 32gb MicroSD class 10. It works great.
Classes are WRITE speed. We had a thread about this the other day and many members confirmed that class 2's were streaming fine... it would just take AGES to put anything onto it

Part of the problem is that the counterfeit market for these is huge and the fake ones have a massive failure rate.
Sandisk Class 2 usually can go up to Class 4 write speeds from my experience, not like it matters for video playback though, any Sandisk MicroSD can pump at least 10MB/s read, more than any 1080p video's bitrate.
I have rooted my nc and its running android 2.3.7 on a sd card. There are times that it works great, but there are times when I click on an app it freezes and I have to do a hard reset. What could be the problem.
What brand is your SD card?

It is speed. Sandisk has the fastest random write speed which is what seems to cause those lock ups. SD card class is just measures one (relatively unimportant) indicator of SD card "speed" (sustained read).
Sustained read and write are great if you're using your card to backup large media or picture files but more or less worthless for running an operating system. Same principle is in place for SSD. Manufactures advertise sustained transfer rates but the important stat for a OS drive is access time (which determines the speed of random read/writes).
Here's a link to a 32gb sandisk for $30 http://slickdeals.net/da/mem-i/p46847290/k4569/u125110/r4
These work just as well as the 16gb ones.
Got this 32gb class 4 few weeks ago - runs great...

32gb is theoretically the maximum, since 64gb cards will all be part of the new SDXD standard. Then again, several people have found that the 64gb SDXC cards work in their SDHC devices so we'll just have to wait until someone tests one in the nook color to know for sure if it'll support it (I wouldn't hold your breath, our hardware is fairly old).
I can certify that the 32gb works fine, as can numerous others who I've seen post.
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.

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.

Aren't speed classes for the microsd cards themselves and have nothing to do with the device loading them? Or are you asking up to what class will the s3 support?

I'm having trouble finding any nice comparison charts that are comparing the newer SDHC cards.
I'm considering...
Samsung MicroSDHC Plus Memory Card - 16GB, Class 10

You might want to go for the fastest class you can afford. This way, when you plug in the sd card in your computer you will be able to load it up quickly.
I really don't like waiting to finish a 30gb dump of data due to a slow sd card.

Despite being a Class10, I have been informed by XDA members that the 32GB Lexar SD card (amazon dot com slash Lexar-MicroSDHC-Memory-Reader-LSDMI32GBSBNAR/dp/B004AM610M/ref=cm_cr_pr_product_top) that I purchased for my Nook Tablet is not very fast at reading large PDFs and eBooks which is what I intend on using it for.
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've used 3 class 10 and 3 class 4's
despite the supposed higher read/write on the class 10, the class 4's all ran faster and were more stable.
I think this is what you're looking for.
http://forum.xda-developers.com/showthread.php?t=1005633
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.
SanDisk's 64GB card is pretty fast on the NT.

I'm running CM7 internal on a 16GB NT. Not sure about speed, but can report on these two brands/capacity.
I have two 16GB Class 10 Samsung cards (MB-MPAGA) and regularly use them to run backups. Used them last night to update to latest CM7 from Team B. They both work with no problems ever encountered.
The card that is in my NT for daily use is a 32GB Class 10 G.Skill that I got from Newegg. No problems with it either.
Attached are results from benchmarks on the three cards.

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.
