My NAS array, testing performances and reliability

I am still waiting on the 4 last hard disks, they should arrive next week. While mounting everything together in the case, I was thinking on the range of tests I may do with this NAS before putting it online in production.

What kind of operating system will I use? 

RAID 5/6
RAID 5/6
Windows XPNeed Windows Server BUT there is a workaroundthrough the Promise EX350 driverI do not want a fully fledged OS for a file server, but want to look at performances
Linux OpenFilerstandard using "mdam"through the Promise EX350 #Linux driverelegant, free and OS footprint can be reduce at it’s minimum
OpenSolarisusing ZFS Raid-Zno driver supportZFS is a great file system, and RAID-Z solve some problem of software RAID5 and Hardware RAID5 at the same time!
