He asked you to try disabling RAID0 and try just a single drive. You may have one slow drive and RAID0 is only as fast as the slowest drive for seeking. Or your controller just might be botched.
Also, don't expect to ever see a 4.5mS access time. Manufacturer #'s don't account for rotational latency of the disks. For 10K drives you must add 3.0mS, which is 1/2 a revolution of the disks. So your drive should see average seeks ~7.5mS
It's probably displaying the "Full Stroke" which is rated @ 10.2
Below from WD sight!
