What SD class does D3 supports?

---

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?
