Any tricks tips to getting more speed because the raid was about equal to me having just 1 samsung 500gig F3.
When I had two RaptorX's striped, that was about what I was getting, 128-135MB/sec. Latencies were about 7.5, and I heard I could have gotten it better.
The cache does matter, but not too much, it's more for the latencies than transfer speed, IIRC.
Incidentally, do you have NCQ enabled through RAIDXpress or whatever it is? That's supposed to help.
