[NTLUG:Discuss] NAS devices

[Ralph]

Howdy,
  I get to spec out and probably buy a NAS for the office.  I see some 2
U servers that have 8 exposed 2.5 inch drive bays.  When I think of 2.5
inch hard drives, I don't think of drives that can take heavy use.  Are
these new drives built better than laptop drives?  Is SAS better than
SATA?  SAS drives seem to go up to 146 GIG and SATA up to 500 GIG.  At
least, that is what Pogo Linux says.  I don't need huge amounts of
throughput.  But, reliability is very important.  Any comments?
Good day,
Ralph
