I recently had an opportunity to repeat this test with the same exact WD3200AAKS (7200RPM consumer grade 320g sata II) drives on an older hardware RAID card, the 3ware 8006-2LP plugged into a 32 bit PCI slot. The results were surprisingly poor given that this card does the RAID in hardware. With RAID-1 Write 1gb: 24.3s Read 1gb: 18.6 Using the same dd invocation as in the previous message, to a freshly newfsd 10GB slice at the beginning of the drive. The drives were strapped to 150MB/S since the 8006 has issues with SATA-II and the interface is nowhere near saturating anyway since the ultimate limit of the head<>platter is reached well below 150MB/S Sticking with gmirror/geom (thank you Pawel) FYI... _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
