Question: I m getting confused with Windows 7 experience index; because on one of my home computers with 2 hard disks 7200 rpm configured with RAID 0 I got 5.9 as score on Disk data transfer rate , ?while ?on another computer which had only one hard disk 7200 rpm got also 5.9 as score ?on disk data transfer rate .
Shouldn t RAID 0 configuration means high read write IO?
Answer: While there is a slight performance increase in RAID-0 for home users, it is not as drastic as many would have you believe. RAID-0 was designed with a multi-user server scenario in mind with multiple random reads and writes at once. Many of the RAID benchmarks are using this scenario, and not a single-user scenario that accurately represents home users. This doesn’t explain why they are identical in the Windows benchmark, but in reality, the performance is relatively close.
