Working this way is essentially giving up control of the hardware to a
third party. If you (or they, or HIPAA, or PCI) are okay with that, and
there's a significant business case, then go ahead. I'd take it slow,

Shorter answer:
1TB or lager, SATA 7200 RPM is going to be a "big drive" where you
should do RAID6. Smaller (up to 450 GB, I think) SAS or FC disks,
usually 10,000 or 15,000 RPM, are the "smaller" drives w
