these two I question.

Both statements are the literal truth. Not that I would suggest abusing your
server class HDs just because they are designed to live longer and in more
demanding environments.
Overheating, nasty electrical phenomenon, and abusive physical shocks will
trash a server class HD almost as fast as it will a consumer grade one.
The big difference between the two is that a server class HD can sit in a
rack with literally 100's of its brothers around it, cranking away on server
class workloads 24x7 in a constant vibration environment (fans, other HDs,
NOC cooling systems) and be quite happy while a consumer HD will suffer
greatly shortened life and die a horrible death in such a environment and
under such use.
Ron,
I know that the drive manufacturers have been claiming this, but I'll
say that my experiance doesn't show a difference and neither do the google
and CMU studies (and they were all in large datacenters, some HPC labs,
some commercial companies).
again the studies showed _no_ noticable difference between the
'enterprise' SCSI drives and the 'consumer' SATA drives.
