Speaking as someone who has run a CDN in the past and one that currently
runs an origin services company, 15K SAS drives work just peachy in the
server environment.  SATA also works but is slower, of course.  Fastest
would be fiberchannel or SCSI drives, but their cost is usually

At this time, I don't recommend 2.5" drives or ones >2TB capacity in a
data center environment.  The 2.5" drives haven't proven their heat
dissipation characteristics to my satisfaction yet, and the 3TB drives
are just a bit dense and again, haven't proven their reliability yet.

Just my opinions, but I do have about 35 years in the business and
about 25 years running various data centers.
