Just setting up my PC which has an Areca 1230 (1gb ECC RAM) Raid-6 card running six Raptor drives. The FOUR new 16mb cache ones (same performance as the Raptor 150) will be used as the boot drive in a Raid 6 configuration. However what would the best stripe size be for this raid-set. As the title suggests its main use will be benchmarking. The other 2 older 1st generation raptors will be used in RAID 0 and will house the PageFile.
Benchmarking ideal stripe size

Normally the smaller the stripe size the better the benchmarks.
I'd be interested to see what the read/write performance of 4 disks in RAID6 is, especially if you could compare it to RAID10/0+1. In theory with RAID6 you should only be reading from 2 of the disks at any one time although it isn't the same pair all the time so I suppose there could be some pre-alignment of heads etc.

After I made the post I thought that I might jut do something like that and try these same 4 disks in a number of configurations. Install OS and then make backup of it onto the older RAID 0 raptor set. Then redo array, copy it over and rebench.
For some odd reason the older 36gb Raptors show up as 36gb capacity in the Areca bios and the newer ones show up at 37gb. I originally was gonna use one of the older raptors as a hot spare, but as it sees it as being smaller than the newer drives I cannot.
