Is zfs on linux reliable enough to be installed with gentoo on a network attached storage?

I have hard time to decide that which filesystem is the best and Raid or not Raid selection. I have 4 different hard disk. 1. 120GB SSD 2. 160GB 3. 500GB 4. 1TB

And I have noticed that zfs on linux does not support trim officially but third party patch, therefore, it is not fully tested....

As a result, I don't intend to let my ssd use zfs, I will use ext4 instead...

So, Is zfs on linux reliable enough to be installed with gentoo on a network attached storage? Or you guys have another good solution for me? P.S. if zfs is reliable enough, RAIDZ is a good choice?

Open Indiana is very reliable but a huge pain to run. FreeBSD has ZFS support built in. however (depending on what you are doing and how reliable you need) I would install it on Ubuntu if there is any margin for error.... if not.. then use Open Indiana or FreeBSD

In your description you mention a set of disks you want to use. If you would use this set in e.g. RAIDZ and one disk crashes, your disk-array would lose all its data.

Reliability is a very broad expression;

If you want to protect your data agains bit-rot, then ZFS is an excellent choice.

If you would use it with your available disks and you would like to protect your data against hardware failures, consider using a more homogene set of disk.

Regarding your selection of OS, try OpenIndiana http://openindiana.org/ or some turn-key OS like http://www.freenas.org/ for relatively simple (but effective) configurations.

Define "reliable enough". If you're expecting bug-free operation, then no, it simply is not there yet. If you're happy to potentially pick up the pieces from a total failure of the file system, then it's good enough.

If your data has any value and you're talking about a production machine, do not touch unproven file system drivers with a barge pole unless you know exactly what you're getting into. A third-party patch for TRIM is definitely living on the edge.

If you desperately want to use ZFS, use FreeBSD where it is more mature. If you're sticking with Linux, I would personally keep to ext4. It's a solid system, and the drives you're talking about don't really demand the benefits of ZFS, in my opinion.
