New FreeBSD Workstation. UFS or ZFS?

[monty]

Hi all,
I am in the process of building a FreeBSD workstation for PixInsight.
The system Spec I have ordered is:

Intel i7 5820K
Asrock X99 Extreme4
64 GB DDR4 Memory Non-ECC Unbuffered
GTX 950 2GB
Samsung Evo 256GB SSD for FreeBsd and application install
Samsung Evo 500GB SSD for PixInsight working project.
Samsung 128GB M.2 ssd for Cache.

Now for optimal performance, should I stick with UFS or go with ZFS. I understand the benefits of ZFS for using in NAS environment and recommended to use with ECC memory (My backup server is FreeNas running on ECC memory), but not sure for PixInsight ?

Hey.

I can't really comment on those file systems. However, when I was last building my Linux box, I used an ext4 filesystem (on the grounds that the code is new, and relatively optimised) but as I had 3 separate drives with a PI cache partition on them (and I didn't care too much around these 'swap' partitions) I created the filesystems with options to speed them up. Things like not updating access times, no journaling etc.

If the files get corrupted, then I might lose some PI caches - didn't seem to be the end of the world to me, and was worth the effort imho. Maybe something similar will work for you?

Cheers -

I run Ubuntu 14.04 and I use ZFS because of:
1. Compatible with Linux, BSD and Mac OS
2. Has compression
3. Is more modern and feature rich

Are you running it with ECC memory ?
I really like ZFS and would like to use the snapshot feature, which will be great before doing any software update. But coming from Nas side of ZFS (where non-Ecc with ZFS is a big no no), I am just concerned about using Non-ECC memory with ZFS, as ZFS relies of ECC memory to avoid checksum error.

I run it with regular non ECC memory and so far no issues.

Here is an article indicating that it is OK to run ZFS with non ECC memory:
