There are also some potential thermal issues with the 73Gig 15,000 RPM drives.

Of course the Xserve RAID is IDE drives only to the best of my=20 knowledge. ;) --=20 Thanks, Josh Paetzel _______________________________________________ freebsd-isp@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-isp To unsubscribe, send any mail to "freebsd-isp-unsubscribe@freebsd.org"
