There really is a reason that SCSI costs more in general, and HP uses good SCSI drives on top of that.
The good reason is that people believe they are better, not that they actually ARE better. Compare some drives side by side of similar vintage and size and you will find there is well in excess of 90% parts inter-changeability.
A reason for us to go to SCSI is that it's sometimes not obvious if an IDE drive can turn off the write-cache or have a battery-buffered write-cache. Both capabilities are essential for databases.
Yes. And another good reason is that they are DESIGNED to run 24/7 for extended periods. IDE drives are not built to the same tolerances. You'll also find the MTBF is much shorter. That said, you can weigh the cost of SCSI and their long-term prospects vs. IDE and their range and figure that into your budget for drive replacement. -- k -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
