Overview

FreeNAS provides storage via Pools. A pool is a bunch of raw drives gathered and managed as a set. My pools are one of these:

  • single drive: no FreeNAS advantage other than health checks
  • raid1 pair: mirrored drives give normal write speeds, fast reads, single-fail redundancy, costs half of storage potential
  • raid0 pair: striped drives gives fast writes, normal reads, no redundancy, no storage cost
  • raid of multiple drives: FreeNAS optimization of read/write speed, redundancy, storage potential

The three levels of raid are:

  • raidz: one drive is consumed just for parity (no data storage, ie you only get (n-1) storage total), and one drive can be lost without losing any data; fastest
  • raidz2: two drives for parity, two can be lost
  • raidz3: three drives for parity, three can be lost; slowest
