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? 
OSSoftware
RAID 5/6
Hardware
RAID 5/6
Remarks
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!
others?

Added value
Test it without breaking your NAS server with the VMWARE image:
FreeNAS is installed on the first hard drive (2 partitions), with a RAID 5 volume for the 3 others hard drive. The IP address configured is 192.168.1.1, with default login/password.

Why choosing itWhy avoiding it
Small, do not need an additional disk for the OSFuture releases?

ZFS: too good to be true

ZFS has so much promise that it sound to good to be true! I will make an extensive try of it soon.

From ZFS: Threat or Menace? Pt. I

.... In a storage industry where the hardware cost to protect data keeps rising, ZFS represents a software solution to the problem of wobbly disks and data corruption. Thus it is a threat to hardened disk array model of very expensive engineering on the outside to protect the soft underbelly of ever-cheaper disks on the inside...
and part 2 is also here

And I also found some benchmarks against EXT3, ResierFS, UFS

will publish soon a lot of ZFS howton as well.
