Amazon has a sale on memory cards today. I'm wondering if the Nook Tablet (rooted) will be able to read the 64 GB cards.
Call B&N and ask them.
It can, yes. I recently purchased this one: http://www.amazon.com/gp/product/B005V7WIA2/ref=oh_details_o03_s00_i00 and it works quite well. It was a little wonky at first, but after formatting it (in the NT) it became readable. Not sure if every 64 gig micro SD will work with the NT, this one definitely does. For me, anyhow.
Right from B&N FAQ
A microSDHC card with a storage capacity of up to 32 GB.
• Class 6 microSDHC cards are supported. Class 6 is faster than class 4, which is faster than class 2. The class should be mentioned on the packaging for the microSDHC card and printed on the card itself. If no speed is indicated, the card is a class 2 card. The speed of the card does not affect page display speeds. It can affect read and write speeds when transferring books, periodicals, and personal files to and from the SD card.
• The microSDHC card must be formatted with a FAT32 file system.

This is a pretty standard description that most devices and manufacturers use. However, I've found that 64GB microSD work fine when formatted to FAT32.
I dont doubt that they will work, but it just isnt supported by B&N so if you get a card that doesnt work they are going to say too bad so sad if you call/online chat with them. haha

Hi everbody, I'd like to know whether it is possible or not to extend the memory of my Polaris with micro SDHC card or only micro SD??!!
Thanks

Yes, the Polaris is compatible with microSDHC. I as well as many others are using 8GB microSDHC cards. Many people have asked this question, and its also listed in many online spec sheets as well as in the manual.
I can confirm the polaris WILL work with the MICRO SDHC because I'm using the 6gb SDHC. I heard it's capable of 32gb maximum.
16GB cards are on their way!
I am more interested in a MicroSD 8Gb Class 6 instead of 16Gb Class 4.
Polaris specs from HTC:
"Expansion Slot microSD™ memory card (SD 2.0 compatible)"
SD 2.0 = SDHC
Specification of SD define max 32GB
SDHC
Hi,
No problems, I use Sandisk 8GB microSDHC wit my Touch Cruise.
Yosi
I use a Sandisk 8g SDHC, class 4, and goes pretty well!!!
do have you view a real difference of speed (program run, take photo, Tomtom navigate) on a SDHC class 4 and a SDHC class 6 ?
(sorry for my english)

I haven't seen any Class6 of 8 Gb MicroSDHC (maybe there is no one??). If i'm right 16gb microsdhc will be available in stores only from december
I don't have experience with changing to a class 6 card, I do have changing from a none classed micro sd to a class 4 micro sdhc card.
I noticed a performance boost specially in loading tomtom.

there will be no ANY differrence betwen class4 and 6 in phone
huge difference will be visible only in data coping on computer using card reader
fast memory cards were doveloped for cameras and other devices with fast readers - our phones are far from this
view this link : http://forum.xda-developers.com/showthread.php?p=2590710#post2590710
The "class number" is for "speed write" and not "speed read".
An application that read data (map,photo,video...) on microSD class 4 or class 6 has same performance.
obviously sdhc class refer to write speed - that is definition
I just do not wite every time "write/read"
reading speed may increase, but it depends on card
it das not changing fact, that in HTC TC will be no visible difference betwen cards - but huge differnce will be in other devices
and yes, I did check it I have two Sandisk card - both read and write speed are different in my card readers (in both readers I have)
hi,what is different between class 4 class 6 of memory card?

hi!
I want to buy a new microSDHC card.
There is the A-DATA Turbo microSDHC 8GB, Class 6 (AUSDH8GCL6)
the Transcend microSDHC 8GB, Class 6 (TS8GUSDHC6).
the SanDisk Mobile Ultra microSDHC 8GB, Class 4 (SDSDQY-8192-E11M) --> is now Class 4 only? wasn't it class 6? -- http://geizhals.at/a330503.html)
I searched the forums, some say the A-DATA is better and the Transcend is quite slow / buggy - but some also say the A-DATA card is slower and buggy...
Some benchmarks / tests on the Hero would be cool
All I can say is I have a Sandisk 8gb Class 6 MicroSDHC card and it does its job really well.
I'm using a Transcend 16GB Class 6 MicroSDHC and is performing quite well.
Does the SD class impact much on the speed of the phone?
Thanks
Phil
I've managed to convince myself it does, I've noticed my phone has been more responsive since upping to a Class 6 card.
I've seen people say that the swapfile is on SD, hence why it seems more responsive. However, knowledgable people have replied that the swapfile is not on the SD, and it can't.
It will obviously speed up anything that accesses the card, though

It was when I got mine. Looking at the (stock) pic, it still looks like a 6 in the top-right, no? I think the site has it wrongly labelled.
shame on sandisk for not giving perf figures on their website though.
there's a good site for SD (not microSD) & CF benchmarks here:
http://www.robgalbraith.com/bins/reader_report_multi_page.asp?cid=6007-9438
it's mostly for camera-types, but there is a USB reader section that should test the raw card. again, not for microSD, but gives an idea, perhaps.
I don't think using a class 6 card is that much faster (or even at all) than using a class 4 card. I can't see any difference in speed in the UI - only in load times.

No, this is a site for price comparison - I've been at 2 shops and they both had the ultra card and it was class 4...
one shop had a class6, but on the package it said class 4. (and it was very expensive)
I think I'll go with the transcend
that's very odd...
Sandisk Ultra speed
Hi,
I got my Sandisk Mobile Ultra 8 GB SDHC card yesterday.
The web shop where I bought it said Class 6, but the print on the card says Class 4. I was obviously disappointed, but as I transferred my old data to the new card using the supplied (really handy) card reader, I achieved a constant transfer speed of about 13 MB/s.
The phone does seem a bit more responsive now, although that may only be psychological. It is definitely faster in Albums and Music, though.
Best regards,
Martin Wiboe
Changing the SD card
Hello Guys,
i am new to this forum, so i hope im posting in the right place
My hero came with a 2GB card, which i used now for a while.
Now i got a bigger card, to switch cards can i just copy everything from the old to the new bigger card and plug into the phone? Or do i need to reinstall something?
many thanks for your help
Arek
Format the new card in-phone first to ensure compatibility, then you can simply copy everything over from the old one.
many thx for that, will try it soon
Arek
Today I got my Transcend Class6 microSDHC card.

My Hero came with a 2GIG card ( I'm not sure what class ) - it was fine but too small.
After a bit of research, I found that the higher the class the faster the card ( ie class 6 is a faster card than class 2 etc ).
I formatted the new card in the phone.
So I copied all my old card files to my computer, then copied them over to the new card.
Put in the new 8GIG card in my phone and it mounted no problem and I had all my music and photos.
BUT -
As I can see, it seems to be a lot slower than my old card. If I go to my photo album, it will load as a preveiw grid. This used to happen pretty quickly, but on the new card, the grid squares are grey, and then start to load up with the photo images.
Any ideas why and ways to fix this?
cheers all
did you buy the new card from an auction site? I hate to suggest it, but there are a lot of fakes around...

Errhhh, this is actually incorrect.
All the class means is that your card is guaranteed to write at certain minimum speeds.
Class 2 - 2mb/s
Class 4 - 4mb/s
Class 6 - 6mb/s
So, if you buy a genuine class 6 card, you are guaranteed that it will write at 6mb/s but that doesn't preclude it from operating faster than this minimum.
A good quality class 4 will often write at 11 or 12 mb/s, more than double the class 6 minimum. You can expect that a good quality class 2 or class 4 will often outperform the class 6 minimum, whereas as poor quality class 6 will perform far closer to its minimum requirement.
When buying an SD card, don't just look at the class - look for independent reviews. For example, http://www.davidgilson.co.uk/2008/12/follow-up-another-micro-sdhc-card/, which shows a class 2 card running at speeds well in excess of class 6 minimums.
Regards,
Dave
This is another case of the Hero having problems with certain SDHC cards.
The thumbnails for the Album are not being created and stored for some reason, and i can almost guarantee this is what's happening to you.
I've had to go back to using my old 2gb for now, as my 8gb Sandisk Mobile Ultra Class 6 was performing poorly when viewing my photo albums. We're still trying to work out why the Hero is not liking these newer cards...
I'm watching with interest....

How sad, I should have noticed this before. Having read your article, I immediately test my two SDHC cards. The finding changes my fundamental view on class numbers:
Transcend Micro SDHC, 8G, Class 6: 9.1MB
Sandisk Micro SDHC, 8G, Class 4: 14.9MB
Note 1: The Transcend card is from someone who sold me a second hand Google G1.
Note 2: The Sandisk card came with a tiny red reader (Like this), bought in Hong Kong
The speed test is carried out using the Sandisk reader in conjuction with the card benchmark software called "ATTO". To my surprise, the read/write speed of this tiny reader is, amazingly, faster than the internal card reader.
That would be this issue.
Still no real solution yet, but its not an exclusive problem.
Hi all!
What class of sd cards is the best for NT? Is it necessary to bay class 10 sd card?
I'm using a Sandisk Class 4 16gig card and it works fine. Absolutely no problems. Haven't tried a class 10 so I can't reliably say whether it would be better or not.
class speed doesn't matter much when it comes to using it with the NT. the reason is because the class speed just represents the write speed, whereas when you use your sdcard in the NT, the only thing that matters is read speed. So I would say a class 10 card isn't worth the money. I would go for like a class 4 or class 6 16gb card. I find that to be the sweet spot. hope that helps
i am using a 16gig hc class 4, show it in a video
I asked that question because i want to bay new sd card for my Nook, but i don't know if nook's controller allow me to use my card in full speed.
I am getting a 32gb Class 10 card (Lexar) that I paid 40 dollars for. I will let you know how it performs once I receive/install.
I downloaded SDFormatter and if anyone has suggestions on formatting or partitioning, let me know. I heard FAT32 but that is all I know.
I'm using an AmazonBasics class 10 32Gb card that I already had in my camera and it works great. I'll probably buy another just like it to put back in the camera.
i've bought a new silicon power's class 10 sd card. SD tools test showed me 15.9 write speed and 18.2 read speed.
Someplace here on forum I have read the best is to get a ScanDisk class 2 or 4 to work with the NT. Perhaps you could do a search on ScanDisk and find the exact post. BTW because of that recommendation that is what I use with my NT and so far so good that is working out great for me.
Manual suggests Class 6. Where did you find the 32 gig for $40?
I'm thinking of formatting my 64GB MicroSDXC UHS-1 card and need to know a few things.
1. Does formatting from extFat to FAT32 cause any card issues? I read it's not good because it can degrade the cards performance and possibly lower it's lifetime use.
2. What is my benefit besides being able to use custom roms (If I wanted), allowing my nandroid backups via CWM to flash to the memory card, and few other things I can't think of offhand. (Medicine does that to you LOL)
3. Why did you go from extFAT to FAT32 on your 64GB MIcroSDXC memory card?
4. Have you noticed any performance or gain going to FAT32?
Thanks for taking the time to read this and help. I really appreciate it!
The card I have is here SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s with Adapter SDSDQUA-064G-U46A.
I have the Samsung 64gb card and I left it at exFAT, I have no issues with the card.
I did switch to TWRP since it reads the card just fine.
I have done several backups and restores with no issues.
I have also flashed a couple of roms.

1. I never worry about that crap. I just back my card up every once and a while.
2. EVERYTHING can read fat32.
3. EVERYTHING can read fat32.
4. Yes. It went from 0 to 100% working with CWM. That's an infinite increase.
It's like this...unless you are going to load high bit rate 1080p mkv movies onto your phone then watch them on a ridiculous 5" screen, then reformat to fat32 and USE the card you already paid for instead of worrying about a card you might have to pay for if this one fails.
My card is on the way. I will probably use use Cwm and format as fat32.

I have the same Sandisk card as you. I changed mine from exFAT to FAT32 because I was having the problem where the card would be reported as damaged once or twice a day. It would say something like "SD card damaged, try reformatting." I could clear the error by either rebooting the phone or unmounting/remounting the card, and all the data seemed to be intact. But it was annoying so I reformatted it to FAT32 about 3 or 4 days ago to see if it would help. Since then, the card has not reported as damaged again, but I have seen it unmount/remount by itself a couple of times.
So instead of messing with it any more, I decided to order the Samsung card, since lots of people are saying it seems to work better in this phone. Newegg has it for $59.99 plus an additional $9 off promo code. http://www.newegg.com/Product/Product.aspx?Item=N82E16820147220
I have used the 65GB card both ways:
-extFAT
-FAT32
The only problems I ran into was with my Debian box. I use Debian as my daily driver, and the extFAT was not recognized. There are ways to add support for extFAT for Debian, but I just formatted it to FAT32 instead and have been using it that way ever since.
Sometimes, on my Windows 8 box, if I try to format it with Windows, it will format it to 32GB. I then have to go into Linux to reformat it to 64GB. Havent looked too much into it, but just an FYI.
Speed-wise though, I have not noticed any difference at all in speeds.
