Makes one wonder if Linux is reasonably usable with 3ware. ;-)
Does anyone have any bonnie++ results for Linux software RAID 5? I know software RAID 5 does not really lend itself to a performant software implementation, but the results would be interesting to see, none the less.
I don't have any hard numbers, but one of my colleagues just doesn't use the 3Ware hardware RAID features because of the performance issues, building his RAID 5 (or possibly RAID 6) arrays in software. Performance screams (=fast).
If he is using 3ware raid cards below 95xx series, raid 5 performance sucks due to the lack of a large RAM buffer. 3ware 95xx cards should have good performance with raid 5 implementations.
