Sandisk 64GB Microsdxc - HTC EVO 3D

I've seen others comment on the 64GB (and up?) microsdxc cards working on the Evo3D but figured there were no details.
Periodically on Best Buy - the Sandisk Class 6 64gb card has gone on sale for $100. I ended up biting and installed it in my Evo3D this week. Initially - the card registers as being "damaged" in the operating system. But tapping on the notice gives you the option to format the card, and you just have to be persistent - eventually the card will format and be fully functional.

I figured I'd comment on the speed. I was previously using a 32GB PNY Class 10 memory card which was not living up to it's speed rating. Using SD tools - the card would only write at 7 megs/second. Which was consistent with other user reports - but still disappointing.
I'd heard that Sandisk has a habit of underrating their cards - so I hoped this class 6 might actually exceed the speed of the PNY card. I would be disappointed. SD tools consistently reports the write speed of this card at 5.5MB/S.
That said - I'm happy with my purchase. I'm very pleased with the additional storage this card gives me and I've yet to see any downfall to the speed of the card - except for the few times I transfer large amounts of content at once. This card is storing my full 23 GB music collection - and still has room for a ton of HD video and games. For anyone curious - this card plays 1080P sample videos flawlessly while using Diceplayer.

I'll keep looking to see if they go on sale any time soon. If they hit the $100 mark, can you post a reminder here for us? (If you happen to see it)
Thanks for the great info!

Will do. I'm curious if our phone will be capable of accessing even larger cards. I'm also hopeful that ICS will allow us to more easily format the card EXFAT so we can have HD files above 4GB. My cheap Chinese Android tablet can easily handle NTFS - so I wish it were possible on the phone.

---

Hmm that hadn't even occurred to me yet, but I agree. That would be a great bonus with ICS!
Also, do they even make cards larger than that yet? I'm on my phone so can't search all that well until I get home. (promise I'm not that lazy lol)

You probably already got home and researched it, but they don't yet make micro SD cards that big yet, but the theoretical max for microsdxc is 2TB. I'm just pleasantly surprised that our phone can handle the new format.

the EVO 3D A cannot read these cards.

It can read it man.....its already been tested when kingmax launched world 1st 64gb sdxc. Evo 3d will format it to a different format i guess.
The same happened with the old phones which were expandable upto 16gb. But 32gb worked fine in them when its launched.

Interesting. I stand corrected. Thanks for proving me wrong. Good information1

****, when did I miss the sale for these cards @ $100????
....I'm so mad

---

I keep checking and crossing my fingers but so far no luck. If anyone sees it at $100 please post something in giant red font so we don't miss it.
Just kidding about the font. Lol

Sorry I didn't report it out . . . I didn't want to be responsible in case our phone didn't work with the card. If it pops up on sale again (it's happened twice since Christmas) - I'll post.
The compatibility issue was just that the card came in formatted EXFAT. Formatting to FAT32 fixed the issue right away. I really wish a future kernel or firmware would allow EXFAT support - so files larger than 4GB could be played. I have a cheap chinese tablet that handles EXFAT and NTFS no problem.

not quite as good....
Isn't this the same card?

I wonder if NTFS and EXFAT could be read if they were compiled into the kernel?

NTFS most definitely could.

That's the same card, yes. It's gone on sale for $100 a couple of times on Bestbuy this year - hence the reason for this thread.
If anyone knows of a kernel that's had NTFS or EXFAT baked in, please reply here. That's probably what I most want out of a custom ROM, though I'm still running stock.

There is another one who fell for the 10 rating. PNY also makes a card specifically for smartphones. It is same price as the 10. I get about 18 write high 20 read. SanDisk you can look for about 6 write12 or so read but they hold up good from what I'm told. Personally I think PNY makes best card now but a lot new ones will be out within year. I'd like to try Samsung when it arrives. Everyone will be using cloud or some type online storage soon. I'd say there won't be much use for bigger cards but wtf do I know? Just guess......

Sandisks are underrated compared to most SD cards. I have a class 6 sandisk that outperforms my class 10 lexar card.

I picked mine up at Best Buy around the holidays for $99.
Just remember to format it from the phone, not the computer . I lost all my previous data because I forgot to.

Grr.
I got a 64GB SanDisk card from Best Buy. It was in the usual cardboard FrustratorExtreme-pack.
It won't format. Not on the phone, not on Windows, not on Linux.
It looks like the device is permanently write-protected. Fdisk appears to write a new partition table, but no...
Windows thinks it's a 32MB unformatted disk that is write-protected. That's 32MB, not 32GB, and this is a 64GB card.

The problem is not with Windows. It's most likely your card reader. I just got the 64gb sandisk from best buy, put it in my phone, formatted fine.
My usb card reader showed it being a wrong size and unformatted even though I had just formatted it in the phone.
Put it back in the phone and did usb storage through the phone and bam, got my 59.7gb of space.
