The 600 MB/s is a burst speed, so it doesn't read that fast for long, as indicated by the fact that your average read is still under 180 MB/s. Regardless, those are excellent numbers! I just wish RAID controller cards weren't a bagillion dollars for a good one.

this one can handle 24 hdds... that would make a crazy fast RAID 5!!! it also supports raid 6 which im not to sure if its better than RAID 5....
good enough

With 24 drives you'd want to set it up as a 23 drive RAID 6 + spare. And yes, it'd be insanely fast. RAID 6 will read at the same speed as RAID 5, and write just a tiny bit slower (Since with 23 drives, RAID 5 can effectively write to 22 drives + 1 parity bit, RAID 6 is writing to 21 drives + 2 parity bits), but with that many drives, you need to have 2 drive redundancy.

And a good controller isn't THAT much if you have a high end build. Instead of getting 2 8800GTXes, get 1 GTX and 1 $350 RAID Controller. Note that loads are very fast. Loading a new level in oblivion only takes about 3 seconds (it takes 2 seconds to get the first bit of the load, then the rest goes instantly)
