I'm assembling a new system in a couple of months, and am facing the
old dilemma: SCSI or IDE disks?

I have traditionally insisted on SCSI disks because they're faster and
more reliable. Lately I've been having some hearing problems, though,
and the drive noise is bothering me. Thus I'm motivated to use IDE
drives in my next system if I can do so without too much compromise.

What about performance? If I run two or or three disk-intensive
applications under Windows, will there be much practical difference
between a pair of fast Ultra320 drives and a pair of fast IDE drives?

Should be, given that SCSI still has the beter access time and IO/s.


I will have at least three IDE devices: two hard disks and a CD/RW or
DVD drive. I'm assuming that each device should go on a dedicated
channel. If so, should I get a mainboard with four IDE channels built
in, or will an add-on adapter work equally well?

There probably ain't a difference unless the extra
channels are on the MoBo chipset. Still, with 2 harddrives
you probably won't spring the PCI bus 132MB/s limit anyway.


What about reliability? Are modern IDE drives reliable enough for all
practical purposes? (I define this to mean a negligible chance of
failure over a system life of three years, with the drives running
almost constantly.) Are there any popular brands or models which have
particularly good or bad reputations?
