I was rather hoping to be able to boot from a RAID5 array, giving me a safety net in case of disk failure but still giving me effectively 3 disks worth of storage space. Using two RAID1 arrays would be an alternative, but that would mean having less space available. I am uncertain of the perfomance penalties of the ZCR/RAIDIOS setup, though the press releases (but the vendors, naturally) imply that it isn't too serious. As for saturating the PCI bus, I have no immediate use for it, nor do I envisage needing it at any time in the near future. - Ruan On 11/29/05, Wojciech Puchar <wojtek@tensor.3miasto.net> wrote: > > raid card for my Gigabyte SR125E machine.
