Sure, transcend has class 6 microsdhc cards up to 16g, but they have no 32g microsdhc, at all.

This is somewhat inaccurate also, as there are different types of writes and reads. But I think we're becoming more specific as we continue this thread, but I'll stop as we both probably know plenty about this.

Found a good article on the 32gb microSDHC

http://www.itproportal.com/storage/n...icrosd-card/1/


Mentions N900 by name.

Good news fingers crossed

You can see it in all the press photos, even on their site:

I don't see any written mention of the speed anywhere, except for "Seamless speed and performance with microSDHC - compatible devices" which sounds a bit sketchy. Are they just trying to say "as slow as your mobile phone is at reading it". What about my desktop card reader?

Thought I would note for those looking and getting these that I received my SanDisk 32GB microSDHC today. Works great with the N810! Speed is a little slow at class 2, about 1-2MB/sec. WRITE speed. But still, 32GB omg! Glad I ordered immediately, looks like they're going to be on back order awhile... I assume they will likewise work great with the N900. I'm curious if the future microSDXC cards will be compatible if formatted with FAT32?

Okay. I answered it myself. Here for everybody else:

Just install Easy Debian and get hdparm with "apt-get install hdparm" in Easy Debial terminal.

Do the test with: hdparm -tT and the device to test.
