I am ordering a new 40gb IBM 60gxp to go along with my Western Digital 40gb 7200 rpm. There is a possibility that I will put these in a RAID 0 config. I realize they are essentialy the same speed, both 7200 rpm and ata 100, but theoreticaly based on benchmarks the IBM drive is a tad faster. What kind of effect, if any, will this have on performance, stability, etc?
