Ummmm, great, how about performance numbers of the arrays so we can have a benchmark reference?
Mike
Mike have already posted benchmark figures for the 12 x 1.5 R5 array in the raid issues thread in the m2 forum.
Once I get the new machine into its final resting place I will be performing benchmarks on those arrays (hopefully this weekend) it is based on an MSI dual Opteron board with 2 x 275 cpu's in a TST ESR-316 case with triple redund PSU's (case came in at £125 what a bargain), Will post benchmarks as soon as I can get them done.

not to shabby I think
Now to verify which array that is?
