ZFS is just too demanding of resources for that rig [1] to usefully support in 512MB of RAM, and 'dumb' controllers do not help. NB: He does have decent power. External housing for the SATA array. Bill [1] Per his dmesg and a google of the various kit reported. Decent PCI slots aside, no longer a match for a current Mac Mini or a Dell laptop w/r RAM, CPU, or FSB speed.
