Where's the next bottle neck in Computer performance? The CPU? Memory? Bus? If a drive can shovel it's info off at a rate of around 30M/s sustained, what relative speed can the computer process it at? Or is there a correlating measure? In other words, am I wasting my time on the S900 by using an ATA133 card and drive, if it won't draw and process data at a rate worthy of the drive's speed?
