Hi.
I wonder about the current state of affairs regarding striping over
multiple SSDs.
Found this thread:
http://marc.info/?t=126787186000002&r=1&w=2
but nothing after that. Was this problem to hard to handle?

Bad form to reply to self.
More googling finally turned up this commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8357422d4bf33bc2c35884d4016c3fc9efbbc1d2
So I'll be ordering 2 SSDs.

To be clear: DM's striped target does support discards. MD's raid0
(or any MD raid level) does not.
