We are using 4x 512GB SSDs (boy, these were expensive!) in a 16-core i7 computer, running in production using PostgreSQL 9.0.0, Glassfish 3.1 and ActiveMQ.

Works great, and we do heavy queries at lightning speed. We currently run Ubuntu Linux on it but would switch to FreeBSD 8.x if the Java support was better.



Which brand and model were the ones you put in the postgres server?


MMDOE56G, that's a Samsung 256GB SSD. [Sorry, I know I wrote 512GB and honestly I don't know why I didn't catch it before now.]


are they raided?


Yes, RAID-1 on each pair.


Does trim work over raid-1? I was under the impression that trim isn't supported in raid at all yet.
