not a bad card from all those who I've seen use it. Recently saw 2 x Vertex 3's hit 1GB/s on it so thought it might be worth a try.
Damned if I could get the friggin' thing working on my Gigabyte board though. Kept dropping drives no matter what drives(3 different matched types tried), firmware, HDD timeout settings and any other tricks that have worked in the past. I hit it with the kitchen sink and it was still a no go.
It's a Highpoint.. so good luck with it.
PS.. I thought R0 was for the peens. LOL
