Re: Improving RAID5 performance (what disks/configuration?)

[Osma Ahvenlampi]

FWIW, Bonnie stats for single-PII-350MHz, AIC7890 v5.1.2, raid-981005, 
and 3 9GB Seagate Barracudas (7200 rpm U2W). The machine was under
normal 18:00 load (a few users still in the office, mail and general
disk access) during the benchmark.
