Hello,
As I understand it, in a traditional RAID 5 setup adding new disks to the pool
provides more overall I/O as the load is spread out across multiple disks.
What exactly is this relationship in a RAID-Z setup? What should one expect in

Hello,
I'm sure this question has been asked many times already, but I couldn't
find the answer myself. Anyway I have a laptop with 2 identical hard disks
250Gb each, I'm currently using Linux on RAID0 which gave me ~500Gb..
I'm planning to switch to FreeBSD but I want to know before I do, what
If you want any kind of data guarantee, you need to go for a mirrored
pool. If you don't want a data guarantee, you can create a single pool
(non-mirrored) of the two devs which will give you 500Gb. The key is
in the 'zpool create' command
zpool create twofifty mirror disk1 disk2
zpool
Since all my data are on this PC and I have many externals HDDs (around 3Tb)
I think I'm gonna go with Mirrored setup, protect my data.. but out of
curiosity, if someday I decide I want 500Gb, can mirrored setup be switched
to single devs on the fly or a complete array rebuild is necessary?

A zpool consists of vdevs (a group of discs). You can create a mirror of your

Each group of discs should have redundancy, for instance, mirror, raidz1 or
raidz2. So you can add vdev to a zpool on the fly, but you can
