First things first, the pool consists of 4 2Tb hard drives and 1 128Gb SSD. Its setup in RAIDZ1 (equivilent of RAID 5)
and then the SSD is set for caching.
To create the pool i ran
zpool create home raidz sda sde sdf sdg
then, to add the cache drive
zpool add home cache sdd
the pool (in my case) got mounted to /home, and then i restored my backup to it. to do some tests, i can the
614MB/s write and 5.3GB a second read is nothing to be sniffed at! 🙂
