My results using Bonnie:
Computer tested on is a home brew:
GIGABYTE K8NPRO-SLI Motherboard - nForce4 SLI Socket 939 PCI-E
AMD Athlon 64 X2 Dual-core 4400 (2.2Ghz)
Memory 2ea. DDR400 1024MB EL TITANIUM OCZ (2Gbytes total)
eVGA GeForce 6200 TC PCI-E 64MB 2N22
USB keyboard and mouse
Disks - All internal and connected directly to motherboard:
Primary - MAXTOR 300GB 7200RPM Hard Drive - 16MB IDE (ATA 133)
4 Disks SATA - WESTERN DIGITAL 250GB 7200RPM Hard Drive - 16MB SATA2 - OEM
(WD2500KS)
Note: SATA disks running in SATA II
RAID5 (zfsr5) consists of zfs software created RAID5 using the 4 SATA disks.
NON-RAID (zfsstd) consists of zfs created file sytem on the Primary disk.
Bonnie was built using Sun Studio11 with the -xarch=amd64 switch.

OBSERVATIONS: The only noteworthy delta is the RAID5 Loaded Sequential Per Char
is 30%
less than the Unloaded condition. The variations in the balance are neglible.
