Hi,
well my server has been going just over a year. Chugging away with it's
1Tb raid. I've used ide drived at home in my server. Very sad experience.
Had 2 drives fail..... The ole server at work hasn't been going long but
we did have a 10 year old hp running with maxtor drives if I remember
rightly in a raid0 config removed from service this year :-). Just how are
the scsi drives different in construction to ide drives? Why are they so
much better?
