Apparently these new 64gb SDXC cards work in some, if not many SDHC devices that do not officially support SDXC. I'd love to put my whole mp3 collection (40gb) and still have room for a handful of movies.
Probably going to get one for my Bionic, but if I know it'll work on the Nook as well I'd get two right off the bat.

It only documents compatability with up to 32 GB... but that does not mean it is not capable of using the 64... this has been common in "computer" technology... they will advertise compatability with the largest drive available at the time.. but along comes something bigger... sometimes it works... sometimes it don't.
Bottom line is... we won't know if the nook color can use the 64 GB sdxc until someone tries.
To the OP.... if I were you I'd try it in the nook first... if it works then you can get another (and let us know either way)... either way you can reformat it to work in your Bionic anyway.
Doesn't it depend on the number of address lines that the uProcessor has (or at least has enabled/available)? A look at the device specifications may actually tell for certain how much memory can be addressed by the NC.

The SD card is a block device, which means it's not directly addressable. It's not a matter of the number of address lines on the uProcessor. It's a matter of if the software driver can issue the correct commands to get to all the data since the bus interface hasn't changed. See here

As I said, it seems many phones that do not "support" SDXC still will mount and use the full capacity of these new 64gb cards if you format them on the phone.
So there is a good chance they will work, but not for sure, especially on a low end hardware spec like the Nook Color. But it seems even the original Nexus and early Motorola Droid phones will use them, so the Nook might too.
Thanks for the response and for the link. Guess I need to research before I provide misleading comments.

I guess I gotta fork over $220 bucks to try out the Sandisk. There is a Kingmax 64gb card for $180ish, but I trust Sandisk.
40g, entire collection. Ah, to be noob again.

Whatever. I ripped my first mp3 while you were most likely in diapers.
Anyway, couldn't quite get myself to spend $220, so I got the Kingmax for $178. Hopefully it'll work as well as the Sandisk. I'll report back once I get it.
Sorry for resurrecting but do we have any updates on this? I've been seeing some pretty good deals on 64GB microSDXC lately and it would be great if they can be used on the Nook Color.
Someone is going to just have to bite the bullet and try it out. Until then all we can do is speculate really.

I bought two Sandisk 64GB microSDXC cards a while ago and can confirm that they work for me. The card has to be reformatted with FAT32 but works flawless afterwards. I've formatted the cards in the devices.
I've used it with a Nook Color, Nook Tablet, Motorola Defy+, Huawei Ideos X3, and even in a Samsung Galaxy i7500. I've used it both with the stock rom as well as with cyanogenmod. Currently I'm using one of the cards to boot cyanogenmod 7.2RC1 from SD on my Nook Color.
My main use is in my Nook Color and Motoraly Defy+. I've experienced no problems so far.
Formating the card in the device takes a while and it looks like nothing is happening. You just have to wait. Once it's finished it mounts the card and you get a notificiation.
What class are they? Do you know the Sandisk part no.?
My cards are class 6 cards, the item# is SDSQY-064G-U46A. I don't know if the item numbers or cards vary in different countries. I bought mine in Germany.
There seems to be a newer version of the card with class 10. I haven't tested it since I currently don't need any more 64 cards but I wouldn't worry about compatibility.

Any chance of you running CrystalDiskMark on those cards and posting the results here or in this thread?

You can download an app from the playstore called "SD booster" to help the read/write speeds if you experience lag on the larger 64 GB microSD card. It helps me out. There is links on google too where it has been bench-tested.
The link for this app can be found here. https://play.google.com/store/apps/details?id=de.mehrmann.sdbooster&hl=en. It reconfigures your caches for your microSD card to help speed up the read/write speeds.
You can pick up another app to bench test your read/write speeds also. Its called SD tools. https://play.google.com/store/apps/details?id=ales.veluscek.sdtools&hl=en
I used these tools to find the right cache size for my 64 GB card and have it performing as good as a stock 16 GB card with no modifications.
I did the benchmark with both cards. The first card was tested with my old notebooks internal card reader:
Code:
Sequential Read : 20.111 MB/s
Sequential Write : 8.460 MB/s
Random Read 512KB : 19.676 MB/s
Random Write 512KB : 2.405 MB/s
Random Read 4KB (QD=1) : 2.794 MB/s [ 682.1 IOPS]
Random Write 4KB (QD=1) : 1.280 MB/s [ 312.4 IOPS]

Random Write 4KB (QD=32) : 1.397 MB/s [ 341.1 IOPS]
I tested the second card in my nook (booted from sd, connected via USB):
Code:
Sequential Read : 16.732 MB/s
Sequential Write : 7.148 MB/s
Random Read 512KB : 18.068 MB/s
Random Write 512KB : 2.559 MB/s

Random Write 4KB (QD=32) : 1.428 MB/s [ 348.7 IOPS]
For comparison these are the results for the internal storage of my nook color:
Code:
Sequential Read : 17.543 MB/s
Sequential Write : 4.311 MB/s
Random Read 512KB : 16.842 MB/s

What MicroSDHC cards have any of you used successfully with the Nook Color? I intend to run Froyo off it until the Honeycomb ports become more stable.
I was considering the Patriot LX Class10 16GB from Newegg, but there is one review saying they had issues. Is this just a case of user error? Has anyone used this card successfully? Any suggestions on other quick cards with good capacity and decent pricing?
I assume this subject has already been covered, but my web searches only got me about 30 tabs open in Chrome and a lot of threads with vague answers that go off topic. If one isn't out there yet, a sticky thread for people to list specific cards they are using would be awesome.
I would appreciate any help.
I've used a Patriot Class 10 8 gig and a Kingston Class 4 4 gig successfully.
The Patriot tests out as a Class 10, significantly faster than the Kingston, yet both gave me UI response significantly choppier and frustrating compared to stock eclair (rooted). Both were similar.
And no, it wasn't the media server.
I put it down as standard using booting from an SD even though other people have commented on SD froyo being snappier. Maybe both cards suck for froyo.

Thanks for the quick reply and the numbers. I would assume the Patriot Class 10 16GB would have similar performance to your 8GB.
I am starting to wonder if the stuttering you are getting is from the Class 4 having too slow writes and the Class 10 is causing errors from being too fast for the Nook's card reader, or general compatibility. Maybe a Class 6 would be a better fit.
Which Froyo ROM did you use?
I used both 0.6.7 (packaged and "raw") and 0.6.8. I struggled with them enough to get the Market running and somewhat decent wifi speeds (though not stellar) and then threw in the towel. When I get bored I'll probably give the eMMC version a shot to see if it's all that and a bag of chips like they say.
And that's an interesting theory. I've not seen any one propose that a card could be TOO fast for the nook. I'd say it's far-fetched but I admit that I'm not an EE.
hello, i am also a newbie with Nook Color and am planning to root my nook. i am also looking for recommendations on what micro sd to purchase to root.
Here's my specs:
Software: 1.1.0
Model : BNRV200
Serial Number : 2010*************
I found another post that tried to start a thread for cards that worked, but the discussion died out. However, it did list a good number of success/fail rates.
From computerpro3:
Known Good
16GB Class 4 Patriot - 5.9, 6.6, 6.7
8GB Class 6 Lexar - 6.6, 6.7
8GB Class 6 Wintec - 5.9 (untested 6.6 and 6.7)
4GB Class 2 MicroCenter brand - 5.9, 6.6, 6.7
4GB Class 6 Transcend - 5.9, 6.6, 6.7
4GB Class 6 Adata - 5.9 (untested 6.6 and 6.7)
2GB Class 4 Sandisk - 6.6, 6.7
Known Bad:
16GB Class 6 RiData - hangs on Android boot screen with 5.9, with 6.6 and 6.7 it boots but gets endless loops of force closes. Tried multiple cards, all brand new.
16GB Class 10 Patriot - same symptoms as above
16GB Class 10 Wintec - same symptoms as above
16GB Class 6 Transcend - same symptoms as above
16GB Class 10 Adata - same symptoms as above

It looks like the Nook just doesn't like 16GB cards for the most part, and I haven't found a completely positive review of a Class 10 card. Perhaps that is a Nook hardware issue (buffer overrun by too much data from card at once), flaws in card construction, or an issue with the ROM and specific cards.
I was going to go with a Patriot Class 10 something, but swoozle's stutter scared me, so I went with a cheap card to at least learn on. Wintec Class 6 8GB is on sale today from Newegg for $11 shipped. If it doesn't work, I can throw it into my photo frame. People seem to like it though. One review notes it having class 10 speed.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820161404
I plan on running eMMC once I get my card.
Swoozle, please let us know if the stutter goes away with eMMC on your cards.
Thanks again.
i upgraded to a new SD card and run antutu to see how fast it is but to my surprise this new class 10 card is not faster than my old class 2 card.
so is there like a hardware limit or why could that be?
both cards have about
6mb/s write and
15mb/s read.
anyone got some better results with a class 10 card?

Some brands are faster than others even if they are from a lower class.
For example, my Sandisk class 2 is faster than a Kingston class 4.
Which brand is your card???

I have a Samsung Plus 16GB Class 10 and get:
According to SD Tools: 12.4MB/s write and 17.2 MB/s read.
According to AnTuTu: 11.3 MB/s write and 14.7 MB/s read.
16GB Sandisk Class 10 (Antutu 2.3.1, 2nd run.)
10.4 MB/s Read
10.0 MB/s Write
The card has 12.4 GB on it of real data before testing.
This is on GR3, which I don't think has any "SD-Card optimization". (Too lazy to check.)
Keep in mind that we don't know, at least I don't, how Antutu tests. If it's testing with a lot of independent reads/writes, the speed will invariably go down. (If copying a single large file from my computer, I get a much higher throughput.)
"Class 10" should only mean that your card is able to sustain 10MB/s of continuous writes, it doesn't say anything about access times/block erase speed (which can influence any benchmark.)
Hi TrymHansen, there is a free app called SD Tools which does nothing but test SD card speeds.
Edit:
FOR ANYBODY ELSE READING THIS THREAD:
The class rating of a card indicates the minimum speed the card will write at. Class 10 = 10 MB/s write speed. Read speeds are usually higher than write speeds.
Anil
Excuse me for being dense, but I don't get the point of your post. I explained in my post what Class 10 means, and then you post as if I asked what class 10 means.

My post wasn't only for you. The first part about SD Tools pertains to you. And anyway your post is incorrect, the Class rating indicates the MINIMUM speed the card will write at. Which isn't the same as a sustained speed.

I can confirm the quality of Kingston SD cards. My 16GB "Class 10" gets the following in SD Tools:
Writing Speed: 7.2MM/s
Reading Speed 13.5MB/s
It's good enough for me as I was considering just getting a Class 6 as I don't exactly do much HD video recording, but if you need the speed - avoid this card!
I am using Sandisk 32gb class 4 card.
Antutu Benchmark
SD card write: 5.6 MB/S

Your SD Cache size matters when u perform SD Speed test in your phone. If you are using CM7 ROM, the default is a mere 128kb cache.
Cache size of SD can be from 128kb to 4096kb and different sd cards will perform better/worst with different cache sizes.
Just thought it would be a good info to share.
why is it that im getting two diff figures when i test my card with antutu and sd tools?
sd tools - read 33MBs
write 6.1MBs
antutu read 10MBs
write 2.6MBs
something doesnt add up
sd read is 2046 default on miui rom
my card is a ridata 8gb class 10
which figure could be correct?

This is sort of true, but if it was a mere cache it would always be a good idea to set it as large as you can afford RAM-wize. This is not the case.
It is a read-ahead cache. In short that means that whenever a read is requested, it first checks the cache to see if the data is already there, if not it reads the amount of bytes specified no matter what.
Increasing the read-ahead cache will help when reading large files, since it leads to fewer (actual) io-commands being executed.
However, if you're reading a lot of small files it will hurt performance, since for every read issued it will read a lot of unnecessary data before it can go on to the next request.
(I also think this is at a block-level, which means that it merely reads the next blocks, not knowing if they actually belong to the file you're reading at the moment, but not sure about that.)

Ive seen 32gb MicroSD..but with class 4. are these ok for D3 or do we need class 10?
I've got a class 4 32GB card in mine and it works just fine. As far as I know it even records 1080p video at that speed. 32GB is the max that it will support as it only supports SDHC and anything over 32GB is SDXC.
I bought a Lexar brand Class 10 (32 gig) MicroSD from Amazon, and things don't load as fast as I thought they would. I had previously used this card in my HTC Desire Z and noticed that my Gallery would load very slowly. I thought maybe it was the Gallery or the ROM I was using or whatever... but then when I moved to my Motorola XT860 (Canadian Droid 3), I noticed the same thing. The gallery loads images / thumbnails very slowly, and sometimes when I take pictures with the camera, the image doesn't fully write to the card (the thumbnail for the picture will show half the picture, and the other half of the picture will be corrupted garbage). Even when I switched my phone over to the Chinese ROM it behaves exactly the same.
I'm thinking the Lexar MicroSD is at fault here... but I would like to continue testing by getting a new one, hopefully made by a better manufacturer/brand.
Hope this helps.
I have the Patriot 32Gb class 10. Gallery works fine with me, even if I have a lot of pictures on it. The only problem I have is with Spotify. When it downloads songs for offline usage, it would whine about the sdcard being corrupt/full even tho it works fine.

Are you using the stock gallery app? If so, try using "Quickpic" its free in the market and loads everything MUCH faster than the stock gallery.
If you are worried it may be the card, use a card reader to test the speeds on your computer. There are a few free applications out there that will do this.
I am using a Kingston 16gb Class 4 card in my XT860, same as the one I used in my Desire Z and haven't had any issues. Though I haven't tried to record any 1080P video yet... 720p doesn't have any lag but the write speed may be a bottleneck for the 1080 video.
I ran a multitude of tests on my Kingston class 4 and it regularly had a write speed of 6mb/s+, which is the minimum speed of a class 6 card. Some people aren't fans of Kingston but I've used a few of their micro SD cards and they have always had good results for me.
Thats a good idea. Ill test the read/write speed on my pc. Ive yet to find an sd card tester app in the market that will work with this rom (stock chinese ME863 rom on gingerbread 2.3.5, rooted)
Thanks!

i will go for a 16Gb class 10 Kingston card, instead of a 32gb class 4 A-data.
speed 10 is more important than 16gb at class4.

Even though they are really expensive at the moment, 64GB micro SDXC cards have been confirmed to work in most Android devices. These cards come formatted by default with the exFAT file system which is unrecognized by Android but Android will format it to FAT32 and all 64GB are accessible. FAT32 has a limit of 2TB, but modern versions of Windows won't format FAT32 over 32GBs. They will still read/write >32GB FAT32 drives just fine.
By the time these cards come affordable Android will probably have exFAT support by default.
Speed issues = return?
This may not really be related, but say I buy a Class 10 card of any size and am getting terrible transfer speeds. That's grounds to return it, right?
I tested my Lexar Class 10 32 gig and some no-name 2 gig on my PC. These are the results. I would appreciate it if any of you could try the same on your card(s) and see how they compare to mine?

That is on your computer. I think the real question here is whether the Droid 3 can read/write at a fast enough speed to take advantage of faster cards. Speed tests on a PC are going to depend on the card reader being used.
Was trying to rule out possible defect with my 32gig. Its pretty bad on my phone. Most photos i take dont write, sometimes half-write. Overall its sluggish. I blame the ME863 rom but im kinda stuck with it for now. For now i just have it set to store photos/videos on the internal flash.

Very interesting.... thanks Eksempel!

Has anyone tried changing their cache size to see if it improves xfer speeds?? There was a tutorial on the homepage.
Also I'm considering on class4 vs class10 32gb card, is it woth getting the faster card? I want to stream 1080p through the hdmi if people could test this then I'd appreciate the results
Changing the cache size probably helps in Android, but not when the sdcard is mounted to the PC. Not sure the phone even has 1080p output via the HDMI (shoot me if I'm wrong), but I can get it to play 720p .mkv files without video stuttering.

Nothing fancy, but works like a charm.
I used a 32 GB "Noname" Class 10 before and I had lots of broken files after a days use....

I have had a 32gb pny class 10 since july. The speed is a little lower then expected, but the real problem is data corruption. I lose several files each day(found in the LOST.DIR) and I'm thinking its due to being class 10. From what I've read, the class 10s have problem with the random sequential read/writes (er something like that, don't quote me). Anybody else losing files on a class 10 card or is it just me?

have you tried puting games or applications on card? when i do that, i lose that game..until a restart the phone. and then i lose another game. and so on...

I experience the same problem, but it's really strange because this never happened on my Blackberry Torch before. I didn't have any instances of data corruption. I also think it's got something to do with reading the files, since I'm really not doing any writes to the disk.
I just got my new tf701. It's running stock android 4.2.2. The Androbench micro scores are worse than my old Transformer Prime. I thought the tf701 didn't have poor performing internal sd like the tfp did. What are your scores? Should I exchange it?
Here're my tf701 Androbench micro test scores:
Sequential Read: 67.12 MB/s
Sequential Write: 14.37 MB/s
Random read: 7.21 MB/s, 1846.66 IOPS (4K)
Random write: 0.82 MB/s, 209.94 IOPS (4K)
SQLite scores:
Insert: 68.15 TPS, 4.4 sec
Update: 85.03 TPS, 3.52 sec
Delete: 82.94 TPS, 3.61 sec
all of them are below the Transformer Prime's.

hello
i just ran mine i got similar results. i think it is wrong as i copy between tab and sd often and copies faster than that result much faster.
i got rand write 1.2
rand read 36.8
no reboot for days.
i ran on 3.2 and remember much higher
so it may be firmware
i wonder what the custom rom that is out gets
anyway it seems like next update may be 3.4 so lets hope its polished.
im happy with performance and since update i have not got garbled screen.
the dock though is still **** and it seems to drain the batt faster when docked then undocked
though havinf a 64gb sd card may cause extra drain?

Thanks. I feel better. I hope more members can post about their AndroBench results.
My TF701 is not running slow. I just want to make sure I don't get a defective one.
I have owned a Transformer Prime (TF201) for a couple of years. TF201 is notorious for having slow internal SD. I ran custom ROMs that had Data2SD. The current ROM on it is Voyager2K's Paranoid 3.99. I don't use Data2SD on it anymore even though that's an option. The reason is my AndroBench scores are excellent without Data2SD, big improvements from the beginning, esp the writes. I don't know what Voyager2k did to make his ROM improve on SD speeds. But the OS itself can obviously make the difference.
My TF201 with stock 4.x ROM:
Sequential Read: 18.07 MB/s
Sequential Write: 3.85 MB/s
Random read: 5.25 MB/s, 1345.42 IOPS (4K)
Random write: 0.21 MB/s, 55.82 IOPS (4K)
The writes are much better even though the reads are not as good
My TF201 with PA ROM 3.99 w/o Data2SD:
Sequential Read: 13.3 MB/s
Sequential Write: 159.77 MB/s
Random read: 4.86 MB/s, 1246.38 IOPS (4K)
Random write: 160.58 MB/s, 41109.08 IOPS (4K)
The writes are much better even though the reads are not as good

I don't trust those scores. Sounds like fsync might be off in which case you can forget the write scores being reliable.
Like in other mobiles, it seems that the 128GB it’s faster that the 64GB version.
Carl commented that the 128GB UFS 2.0 storage performs much better than current microSD card implementations

OP3T uses NF2S vs 0P3 ext3.. which could/should explain faster write speeds..

I'm pretty sure it is F2FS on 3T. It was also mentioned during the AMA session. Besides, there is no such filesystem as NF2S.
F2FS on 3T -- EXT3 on 3
