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
