Yeah, that's my big problem with anything IDE.    My personal experience of
failure rates for IDE drives, for example, is about 1 out of 10 fails in
service before it's a year old; SCSI has been more like 1 out of 50.

Also, while I've seen benchmarks like Escalade's, my real-world experience has
been that the full bi-directional r/w of SCSI means that it takes 2 SATA
drives to equal one SCSI drive in a heavy r/w application.   However, ODSL is
all SCSI so I don't have any numbers to back that up.

But one of my clients needs a new docs server, so maybe I can give an Escalade
a spin.
