Interesting-- what is the suspected impact of not having TRIM support? I would imagine this might cause slow writes after some time of use, since the OS isn't able to tell the drive what blocks have been freed, so the drive doesn't get a chance to "pre-erase" those blocks before another write comes along that would occupy them anew. I'm contemplating a similar setup for some servers, so I'm interested if other people have been operating pure-SSD zpools and what their experiences have been.
