Ah! I see. Thanks for the clarifiction Leon!

No, its just a single partition. But the "single disk" is a hardware
RAID5 at one end. (The other backup end is a SATA drive)

Is it still pretty much typical that the disk is the bottleneck? Not
CPU/memory etc.?

In spite of the diff computation etc. does disk seek remain the
bottleneck usually.
