Claudio> What brand of SSDs are we talking about?
I tested two different products that both exhibited poor behavior during
frequent resets/power cycles. I can't really disclose details but rest
assured I'm working with the vendors in question to get this fixed.
Just last Friday I received a couple of updated drives that appear to
work correctly. But I haven't tested them extensively yet.
Claudio> What filesystems did you experiment with?
Some tests were done with ext3 but most tests were done using my own
integrity checking tooling and/or dt.
In the filesystem case it was trivial to map out the affected files in
debugfs and correlate those to a logical region on the disk.
