I'm running a server with 3 RAID5 arrays through an ARECA 1880i coupled with a HP-SAS Expander. After experiencing a massive degradation in performance lately, I want to benchmark the drives individually without breaking the array. The arrays consist of 6x2TB drives each.
How would I go on about achieving this?
The server is currently Windows-based (although I question the relevance of further system-info).
