certainly not. PCIX is something you don't have. PCIe2 - yes > > I'm currently just using a single large partition & ext3.

Btw, why ext3? 4 and trim is your friend with a ssd. Your performance is fine. It is a single slot adapter, so the theoretical max is 300mb/s. Now substract some for overhead and some for misalignment and 200mb/s aren't bad at all. -- #163933
