Well, even with current TSM levels I would only use 15kRPM disks in
RAID1. DB2 has no software mirroring, but your OS might very well do
the job for you, I know that Linux and AIX can, and I think recent
windows levels can do the same. RAID5 or RAID6 are great technologies,
but I don't believe that they mix very well with high performance
databases, not for TSM <= 5.5, and not for DB2 either.

SATA disks are only useful in very small TSM environments (up to a few
gig database), and well, that wont change much with DB2.
