64 GB micro SDXC

I may be wrong but at least in the 3d (same as v 4g) can only hold up to 32 gb

Sent From My HTC Evo 3D Using TapaTalk 2

Most devices state that because 32 GB was the largest card until recently, I don't believe that it's a technical limitation. I've read over at xda that people have 64 gb SanDisk cards running in the Evo 3d after formatting in the phone.

64 gigs?
Might as well carry a laptop around.

I use my phone as my primary media player, got a 32 GB class 10 when I bought the phone 2 months ago and I only have 1 gig left. I prefer to stream my music from the card as opposed to using the cloud. It's not like it'll weigh more with the larger card. ;-)

Best Buy has one 64GB SDXC for sale (online) right now for $60. One reviewer at Best Buy claimed that theirs actually delivered as a Class 10. I found similar reports on XDA regarding an Amazon item.

I got a 64 gb class 10 SanDisk for $70, the class 6 was $60 on ebay. NewEgg wanted like $78. All my media took up almost 25 gb and with backups on this phone using almost 1.5 gigs I have run out of room. The 64 gb should hopefully last me forever and a day. You can easily see the difference in photos, the class 10 has a u with the number one in the center, the class 6 doesn't have that logo. The Best Buy ad states that it is a class 6.

Yes, I understand. For a card this size, it would certainly be beneficial to be guaranteed the faster speeds of the class 10. I'm not sure it would make any difference (class 6 vs. class 10) in the actual operation of the phone, but the class 10 would certainly be handy when moving large amount of data back and forth.

There does seem to be some serious confusion on the speed branding. I noticed that the first 2 photos (out of the 4 photos posted) on Sandisk's own Amazon sale (class 10 UHS-1 card) are the wrong product. The second pair of photos appear to be correct.

Even stranger, the reviewer at Best Buy that claims he got the class 10 card after ordering the class 6 card is posting similar speed results to that of the Amazon class 10 purchasers. With Best Buy not even carrying the class 10, either he has a really high quality class 6 or they accidentally shipped him the wrong sdxc card.

The way to tell for sure is to check the markings on the card, just ignore what the box says. Might have shipped the card in the wrong packaging.





Yeah my guess would be that he got lucky with an improperly binned card.
Or maybe it can't sustain those speeds at higher temps and that's why it was binned as a Class 6 might be able to sustain class 10 speeds just not under all scenarios .

This SanDisk 64 gb class 10 smokes my GSkill 32 gb class 10. I'm seeing average writes of 9.8 mb/s vs 8.9 and reads of 29 vs 22. And I formatted on the computer also just so I could test and control allocation sizes. Microshaft never makes it easy though, OS refuses to format fat32 any larger than 32 GB, had to go with Easeus partition manager.

Can anyone tell me how to do this before I tear my hair out?

I keep reading that formatting a 64GB to NTFS won't work. Everywhere I read has instructions for 32GB cards, not 64GB and say that Vista has some artificial limit for 32GB.

Should I try (via Computer>Format) Allocation size 4096 bytes and NTFS? Will that work?

Edit: I'm trying this method: http://www.xoomforums.com/forum/mot...-format-sd-card-especially-64gb-fat-32-a.html

See my post right above yours. Google for the partition manager, it's free for personal use. I tested and found 32 kb allocation size to be the fastest without a ton of slack space.

I tried doing it on my PC via this method: HOW TO - Format an SD Card (especially 64Gb) to FAT 32

I DON'T recommend doing it the way Post #1 instructs. It took nearly two hours (!) and my PC then informed me that the card was too big.

Further down in that thread, someone mentions putting the 64GB SDXC card in my Samsung S3, selecting "Format" and it does it within a minute! If I knew that initially it'd have saved me a whole load of hassle!

There's not a lot of help out there about formatting 64GB MicroSDs on the web right now, which is why I was getting so p**sed off!
