Playing with ZFS (and FreeNAS) again.
I was wondering which way I should setup the RAID array for maximum throughput (speed), and with a bit of searching came across a fantastic article (found here)

The author does many comparisons of RAID 10, and 5 (raidz1), 6 (raidz2), for up to 24 drives to show how performance scales with # of drives as well as which raid is chosen.

Also since ZFS offers realtime compression, there are comparisons of with compression on (both lz4 and lzjb) and no compression.

Excellent read and great reference. Saves me a bunch of time.

For my 4 x 1TB drives, I’m going with a raidz1 (RAID5) with compression turned on to lz4. I can’t wait to see what kind of throughput I can get out of these disks.
Sadly I will be limited by the 1Gb ethernet connection at around 100MB/s transfer speeds.

I could always bond a couple of 1Gb connections to increase the network capability….
