Ok, let me ask the question again... I have 2, possibly 3, 320gig SATA drives. I want to build a RAID array that will maximize the speed of read and writes to the array. I have no concern with redundency because I will archive what I wish to keep to another drive. Using mdadm or lvm2, what type or RAID setup should I use? thanks, Steve _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
