So I've built a zfs raidz2 storage pool out of four 2TB WD EARS (green power) drives. I'm not expecting super performance out of these drives. I'm mostly just double-checking to make sure my array is running as ideally as it can.
Informal benchmarks with dd(1) shows about 40 megabytes/sec write performance. I haven't done any system performance tuning yet.
The system is running FreeBSD 8.1 amd64 with 8GB of registered ECC RAM. The CPU is an Intel xeon X3430 ("lynnfield") running at 2.4ghz. The drives are attached to the Intel ICH10 SATA controller running in AHCI mode. FreeBSD is using the ahci(4) driver. I'm using the raw drives with no fdisk slices on the drives.
Does this seem like reasonable performance?

Code:
# dd if=/dev/zero of=test.dat bs=1M count=10000
10000+0 records in
10000+0 records out
10485760000 bytes transferred in 226.371684 secs (46320988 bytes/sec)
