If I might jump in here, how about experience? I have a server at work that has an 18 GB Quantum SCSI drive (purchased 1999) and a 20 GB IBM IDE drive (purchased 2000). They are set up as mirrored drives. Why not both SCSI? Boss got cheap when I told him we should have some reduncancy. :-)
Anyway, I've had to replace the SCSI drive 3 times (you should hear the sounds it makes when it dies - really cool). IDE has never died. In my mind, SCSI sucks. More money, lower quality. Thank God I had the IDE mirror or I'd be hooped. :-) Ian > -----Original Message----- > From: S�bastien Taylor [mailto:[EMAIL PROTECTED]] > Sent: Friday, September 27, 2002 2:33 PM > To: [EMAIL PROTECTED] > Subject: Re: (clug-talk) How do you fsck the root partition? > > > Hahahaa, ok humour me a second, where do you get top of the line IDE > is faster than SCSI?
