In case anybody is interested, I found this blog entry (in Japanese) that reports the ZFS performance of HP ProLiant MicroServer (8GB mem, 4x2TB hdd):

Here's the bottom line. iMac AFP I/O speed in different RAID configurations:
Simple Stripe (RAID0)
1073741824 bytes transferred in 3.175971 secs (338083003 bytes/sec)
Stripe of Mirrors (RAID10)
1073741824 bytes transferred in 4.497144 secs (238760829 bytes/sec)
raidz1 (better RAID5)
1073741824 bytes transferred in 5.718750 secs (187758133 bytes/sec)
raidz2 (better RAID6)
1073741824 bytes transferred in 7.782485 secs (137969019 bytes/sec)
All saturates GbE (125 MB/s) but the blogger thinks RAIDZ2 is a bit heavy for this server (fairly high write CPU load and slow resilvering process). Lastly, he comments on how quiet it is.
Apparently, HP MicroServer is pretty popular in Japan.
