File Copy Test - Read

The nForce4 dominates our FC-Test read results, sweeping the ICH7R nearly across the board. Intel pulls within striking distance with the ISO test pattern, which consists of a small number of very large files, but it's not even close otherwise.

Looking at overall array performance, RAID 5 finally finds some redemption and even leads the field in a couple of test patterns. RAID 10 and 0+1 also perform comparably well. Notably, though, RAID 1 doesn't offer much of a performance boost over a single-drive system. Overall, read performance doesn't scale nearly as aggressively with RAID as file creation performance does, despite the fact that three- and four-drive arrays continue to cluster at the front of the pack.
