I think I did this: turned off ncq (per Josh's suggestion) turned on write caching (it's on an oversized ups and the data isn't critical) set storsave to "performance" changed the memory interleave (thanks to kirk's suggestion). It was off by default. used parted to create gpt disklabel set noatime and one other option that was suggested here for the RAID partition used mke2fs -j -b 4096 /dev/blah That was it. Also, I tried the same array as a RAID0 device on the same box and the performance was approximately the same (maybe ever so slightly faster). Cheers,
