Thanks for your reply.

Sorry, I should have asked "Does anyone have any performance figures to 
share, using md RAID with these PMP interfaces?"

I'm not sure what you are refering to when you say "PMP's bottleneck", 
but I have seen benchmarks for a 3124 host adapter in a Mac G5, attached 
to a 3726 based PMP, which had 5 7200 Maxtors connected to it.

It was RAID0 striped and achieved 226MB/s write and 253MB/s read.

I was just interested to see if anyone had tested a similar md RAID 5 
using these chips on Linux.

Regards,

Richard
