Right, thanks for the tip.  :-)

We need a lot of storage space, and believe the applications will benefit
more
from available memory (the database is cached for reads in memory, and
unpacking the objects from the database is rather CPU-, if not
disk-intensive)

I see there are some 1TB "Near-line SAS" disks available, does anyone have
experience with those disks vs. regular SAS or SATA disks?
