No particular problems. The SATA drives are fairly recent models in 160G, the PATA is prior generation in 120G, all Hitachi. The SATA drives seem to handle seeks from multiple processes better than the PATA, better even than might expect from striping. At about 4500 hours of runtime one SATA drive developed a bad block which the drive firmware was not able to automagically substitute. gvinum shut down. I see no reason why a SATA drive should be less reliable than a PATA drive. Also remember back when one could purchase the same drive hardware in either PATA or SCSI, so find it hard to accept the interface makes much difference in reliability. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
