Software RAID1 (Mirror) or ZFS Mirror?


Post by morph »

I have 2 disks each of 2TB and am currently building a new NAS.
The PC is an old(ish) HP PC with 3GB RAM and a Pentium(R) Dual CPU E2160 @ 1.80GHz.

I'm not sure whether to use a Software Mirror or a ZFS mirror?
I read somewhere that ZFS is more CPU intensive so I'm not sure whether my processor is fast enough.

What is the better option of the two using the above equipment?

If your system is using ECC RAM then you can go for ZFS, otherwise you should better use Software RAID 1
