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.
SanDisk's 64GB card is great!

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.

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.

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.
is sandisk class 4 going to be recommended again?
On the Nook Color I've read the sandisk are usually the most stable and the class 4 was the most idea (even over higher classes.)
I was wondering if this is still the case before I spent 20$ on a 16 gig sd card.
Without a doubt. It has to do with sandisk class 2 and 4 cards providing random access to small amounts of data at speeds that are 10-100 times any other brand.
All the other brands are trying to make really big chunks of data write faster (think copying over movies faster) so I don't see anyone competing with sandisk here.
you didn't specifically mention what you were going to do. if in theory you plan on running cm7 on a sd card, then go with sandisk class 4. If you are only using it for storage and plan to run cm7 off of internal you can get a higher class rating for higher transfer feeds of large movies etc. unless you plan on running applications off of sd card where I think you would want the sandisk.

I'd suggest class 10 honestly ...
I have a Kingston class 10 16gb and a SanDisk class 4 32gb and the class 4 SanDisk trumps the Kingston everytime, except during transfers directly from a computer. The SanDisk benchmarks much better also

I saw 10 card in another thread (since deleted?) where someone posted about a sale on a 32GB class 10 card. Without researching the card I happily posted to the thread saying that class 10 sounded like a good idea as I like to write gigs and gigs of data (MP3s, videos) to the card for consumption. I didn't stop to think about random reads or writes nor did I consider other uses.
This same kind of info was then posted there. I removed my foot from my mouth and noticed that, yes, in most cases, normal people doing normal things (i.e. running apps, writing small files, etc.) will generally be more happy using a class 2, 4, or *maybe* 6 in their tablet. Save the class 10 for the high-def video camera that needs fast, sequential writes. Save the dough when getting a card for your tablet: do some research and pick the card best for you based off REAL-WORLD BENCHMARKS. (Save you some time - you generally will do just fine picking up a SandDisk card.)
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?

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.

The newer SanDisk UH1 cards are an exception to rule. They have excellent small-block random write speeds. (A link to CrystalDiskMark scores may be found at iamafanof.wordpress.com) My son's been running CM10.1 from an external SanDisk 64GB microSD card for over a month and hasn't had any problem with racing-car games from the PlayStore.
I've been using that card for the last 4 months. Haven't had a problem yet, it's blazing fast for media I put on it. Despite having over 5,000 epubs and pdfs, over 5,000 pictures and over 100 videos sent from phones. I install apps onto the internal though. So haven't tested any of that.
