You can't quite trust your data to SATA just yet it seems

People often wonder why I have 3 15k RPM SCSI drives in my workstation at home in the year 2005. 2 reasons: I can, and I also seem to have a lot better data lifetimes with these drives. Most systems these days are I/O bound and once you get a disk subsystem that can pump data at high rates, even slower CPU machines "seem" a lot faster.

This study of SATA drives seems to back up my armchair diagnosis:

I can tell you from first-hand early adopter experience. I bought the hype of promises of high transfer rates and exceeding low error rates and I have gone through five different SATA drives in the past few years.

There are quality issues in both drives and controllers and as we have discussed. I have faith in the SATA spec. Faith in reliable hardware dwindles.

If only high transfer SCSI was more economical...
