RAID 0 results are very interesting. The difference between the SuperTrak and Escalade jumps out: the Escalade scales very nicely as more drives are added to the array while the SuperTrak's performance stays about the same.

Each drive added to the Escalade delivers a significant performance increase in Workstation, File Server, Database, and Random Write tests, especially under Heavy loads. It's nothing less than what one would expect from a card capable of load balancing: as more drives are added, I/Os may be distributed over each of them, significantly increasing performance.

That said, we're unclear on why the Sequential Write scores don't improve much after the 3rd or 4th drive is added to the array - the Escalade's sequential write performance tops out at "only" 60MB/sec in these tests.

On the other end of the spectrum, the SuperTrak's Workstation, File Server, and Database scores increase by only a few IO/sec when going from a single drive to a 4-drive RAID 0 array. This is disappointing... the SuperTrak is certainly not inexpensive compared to other ATA RAID solutions; we expected much better performance.

SuperTrak's Random Write performance does increase as more drives are added (the sudden drop-off under Moderate and Heavy loads with a 4-drive array is interesting, though). These improvements are likely due to write caching by both the controller and the drives themselves. Sequential Write performance increases somewhat with two and three-drive arrays, then, for some unknown reason, dramatically drops off in a four-drive configuration.
