I'm using a Hackintosh with a Gigabyte x58a-ud3r which has 6 ports on Intel ICH10R controller, 2 ports on Marvell 88se9128, and 2 ports on a 88se9128 pci-e 2.0 card. The Zevo drives are just on the Intel controller, using 2 vdevs with 3 x 2TB Seagates in each. Pushing 400-600MB/sec.

The OS X RAID cards are insanely overpriced, and a waste too since they're just going into JBOD. Anyone know a good HBA/JBOD card thats cheap? IMHO, you're better off buying a good motherboard with good SATA controllers, and buy some more PCI-e ones if you like.

MacPro 2009 octo with 24GB RAM. Hard rives are in first 2 built-in bays, i use 2x3TB Seagate Barracuda as mirrored pool. Write average is 130MB/sec, read average is 230MB/sec when tested against 30% full pool. Not bad, but:
1) both read and write performance seems uneven over the course of test. Write is between 90-170MB/s, read between 100-280MB/s.
2) when tested agains empty single HDD with HFS+ the throughput was much better. Don't remember exact numbers, but write was around 145-150MB/s, read was 180-190MB/s.
Still i prefer zfs for reliability.

ZEVO zfs on 16 GB SDHC, Class 10 Card:

zfs = ~1MB/s
HFS+ = ~21MB/s

Yikes!

ZFS slower than HFS Plus (not a success)

Uneven – throttling?

Throttling, maybe?

Nope, just quick test. How do you measure success without failures? :D Point taken though.
