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

Hardware

LSI 8-drive SAS board passed through proxmox to hive as "PCI Device": Melange-LSI-board.png

Drives:

Pool Capacity Type Drives
sassy 0.2 TB single 250GB ssd
splat 3.6 TB raid0 1.82 TB hdd x2
mack 0.9 TB single 1 TB ssd
reservoir 2.7 TB single 2.73 TB hdd
grim 7.2 TB raid0 3.64 TB ssd x2

Original drives, it's one of the 250GB...
