I've used various Seagate SCSI drives exclusively in all of my boxes and only had one failure, which I was still able to recover all the data from before replacing it. The first box I built back in '97 had an UW Seagate in it that I bought used, and it was very heavily used for 2 years, and I still have that original configuration for various small projects. Right now I have 4 boxes with Barracuda drives (7200RPM) almost to the ceiling in a closet at one site that temps can get up to 80 degrees F, with a constant fan on them, all doing fine.. I build a couple boxes with Seagate Cheetah's in them, for a guy who has an ISP out of his house. He also has (literally) 12 cats and dogs whose hair ends up in the filters of his servers. They too are heavily used, and have had no problems. It's almost like it goes on luck. ;-) At 08:47 PM 9/20/2000 -0400, Sergey Babkin wrote: >"Aleksandr A.Babaylov" wrote: > > > > David Scheidt writes: > > > On Thu, 21 Sep 2000, Aleksandr A.Babaylov wrote: > > > :I work since 1991 with computer hardware and know exact > > > :that SCSI drives is about ten times less reliability than > > > :IDE.
