If you depend on I/O I would recommend you to change this raid with PERC6/i (looks like this is Dell server) which is little more expensive, but comes with 256MB battery backed cache. In my experience mpt devices are crap, and their performance is worse then software mirror. PERC6/i is something totally different :) It's again LSI product branded from Dell and it works with mfi driver. The only problem in the past with them was the management utility which was linux binary, but today there is official native tool in ports, and in 8.0 in base install there will be a tool to manage your controller. Well this wasn't that big problem compared to mpt which cannot be managed under FreeBSD at all?
