Even RAIDed Intel Es don't get the performance that the new huge capacity raided PCI-X drives say they'll get. It's hard to know though based on paper specs, with spnning hard drives there were a ton of variables that allowed manufacturers to claim retarded stats, but as we get to the point where a new drive should perform the same for everybody, no matter what you're doing with it, the margin for exaggeration keeps getting smaller and smaller, so theoretically SSDs should perform very close to their actual specs. Maybe I'm dreaming. But still, the new drives should outperform RAIDed Intel drives. Likely, since it's a closed system, they're able to optimize the RAID controller a bit and grab a bit of extra performance. Also having the drives on a PCI-X lane or 4 should help alot with real world performance.
