I went through this determination when setting up my pool. I decided to go
with mirrors instead of raidz2 after considering the following:
1. Drive capacity in my box. At most, I can realistically cram 10 drives in
my box and I am not interested in expanding outside of the box. I could go

pocket book to expand two drives at a time instead of four at a

have a lot more flexibility with mirrors when it

I would like to get your recommendation how setup new pool.
I have 4 new 1.5TB disks reserved to new zpool.
I planned to crow/replace existing small 4 disks ( raidz ) setup with new
bigger one.
As new pool will be bigger and will have more personally important data to be
stored long
A pool with a 4-wide raidz2 is a completely nonsensical idea. It has the
same amount of accessible storage as two striped mirrors. And would be
slower in terms of IOPS, and be harder to upgrade in the future (you'd need
to keep adding four drives for every expansion with raidz2 - with mirrors

Thanks for comments
So possible choises are :
1) 2 2-way mirros
2) 4 disks raidz2
BTW , can raidz have spare ? so is there one posible choise more :
3 disks raidz with 1 spare ?
Here i prefer data availibility not performance.
And if need sometime to expand / change setup it is then that time
