Robert, I think I already sent out this link that documents FreeBSD R5 performance: http://www25.big.or.jp/~jam/filesystem/ I recently saw an article documenting similar benchmarks using geom and vinum in a Japanese FreeBSD magazine and the handbook section around vinum does warn about write performance of Raid 5. For lot's of applications though the Raid 5 low write performance is not an issue. (it's not an issue for me) Were you able to get gvinum raid 5 working? Could you share that experience? I'd really like to use gvinum or raid 5 with a 3 SATA drive, + 2IDE drive setup but so far I have not been able to get it to work. :-( IJ On May 12, 2006, at 6:35 AM, Robert Fitzpatrick wrote: > I have looked into and tried FreeBSD 6.0 Vinum and GEOM RAID in our > PIII > SCSI 80-pin server with the help of several here on the list.
