Some sort of ATA Raid is probably worth considering - e.g. I am experimenting with a system using 2 ATA-66 Seagates + 1 Promise TX2000 The disks themselves give fairly poor performance when attached to the std IDE channels : sequential write 15Mb/s sequential read 20Mb/s But attached to the Promise card using RAID 0 do considerably better: sequential write 52Mb/s sequential read 52MB/s Now you would probably not use RAID 0 for a "real" system (unless you had good backups), but the difference is interesting Note that even including the card, this is a very cheap setup. (I have not gotten around to testing random read and writes, but if anybody is interested I can test this and supply figures) regards Mark Steve Crawford wrote: > > >Talk about timing...this article posted today seems quite apropos >(spoiler: SCSI beats IDE): > >http://hardware.devchannel.org/hardwarechannel/03/10/20/1953249.shtml?tid=20&tid=38&tid=49 > > > >
