“FreeNAS supports sharing your files using FTP, NFS, CIFS
(Samba), AFP, rsync, iSCSI, and so on, and it also offers software
RAID (0,1,5). With many advanced features, including
Oracle’s ZFS file system,
it’s the perfect companion to store files for
your Linux desktop computers in a central place. Moreover, FreeNAS
has very low system requirements, as it needs only 128 MB of RAM.
This makes it attractive to blow the dust off an old Pentium 2 or 3
PC, put a couple of hard drives in it and make it a NAS. Of course,
for high performance the machine still needs enough RAM and CPU
horsepower, especially if you want to use ZFS, which needs a
minimum of 4 GB RAM to offer some decent performance.”
