What is the best file system to use on NAS, ext3, ZFS or XFS?

[Moi]

Not a Linux expert but ZFS runs in user space so avoid that for performance and stability reasons. XFS and ext3 are in the kernel and for our small NASes would guess that it's much of a muchness.

Basiclly,

ext3 just can support 8TB, tranditional file system in Linux.
xfs can support over 16TB , and quick access on small/big file ,quick remove file.
zfs is newly file system , over 16TB, support snapshot .
So, for your application you can choose different file system.

Thecus N5500/N7700/7700PRO/N8800/N8800PRO support EXT3, ZFS & XFS file systems. It is up to exist 3 set of RAID volume in one unit at the same time.

There are some limitation of these three file system,

@ext3 supports up to 8TB for each data volume.

@zfs is use for snapshot function only. In Thecus NAS, it is limit to exist up to 1 RAID volume that using ZFS format at the same time. For more ZFS limitation, please refer to esupport.thecus.com/support/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=122

@xfs supports larger than 8TB and all functions, but it doesn't support quota function.
