I checked the disk picture - this is a RAID disk array with 6 drives, with a bit more than 1Tbyte total storage. 15,000 RPM. It would be hard to get more/faster disk than that.

What kind of RAID?  It's _easy_ to get faster disk that 6 drives in
RAID5, even if they're 15,000 RPM.  The rotation speed is the least
of your problems in many RAID implementations.

Oh, and the driver rev means a lot too. Some older driver revisions for some RAID cards are very slow.
