read benchmarks: ufs/zfs/ext3 raidz/raid5 Dan Naumov Wed Jun 24 14:00:37 2009

Another FreeBSD person on a forum I frequent did some read benchmarks
on his system: Athlon64 3500+ with 2GB DDR2 SDRAM, a WD 250GB system
drive, and 5 Seagate Barracuda 750GB SATA-II data drives. ZFS and UFS
testing was done using FreeBSD 7.2-RELEASE amd64, and ext3 testing was
done using Ubuntu Server 8.04-LTS amd64. The used disks do not support
NCQ, so there is no "NCQ advantage" on the Linux side.
