They should be much more reliable than regular USB sticks due to their SLC memory.

:A couple of questions still need to be answered though: :* Which OS are you planning on using? Ubuntu 12.04 is recommended Ubuntu 12.04 is our current preferred OS
That should work fine.
:* Which filesystem do you want to use underneath the OSDs? Whatever I can get to work best in testing :) Since this is for a research platform not a product I'd likely start with BTRFS and see if it is "stable enough" and "performant enough" with fall back to XFS if needed
BTRFS is indeed the best in terms of features. I'd recommend using a recent kernel like 3.5.
