FreeNAS は32MBの CF にインストールできる．

At a minimum a basic PC with 96MB system memory, one hard disk and a network card is required. For a production site it is recommended to have a backup process in place or at the minimum use disk mirroring, also known as RAID level 1. For this configuration FreeNAS requires 3 disks, although one of them can be a compact flash card with suitable IDE adapter, minimum size 32MB which is very cheap to purchase. Most systems have four IDE adapters, allowing two regular hard disks and one compact flash drive to be attached.
