Hi there, this is the latest entry in the community's noob list speaking. I am looking for your opinions on a possible HDD design in a small FreeNAS box, because I haven't really found a straightforward answer to my questions.
I have installed FreeNAS on an HP Microserver that was lying around unused to see how it looked like. At the time I only had 1 spare 1 TB drive so that's what it's currently running with. I have just installed a jail with Plex and transferred a few movies. So far it's working fine, but before making a final decision to keep it or not I would like to increase the drive capacity and put it under some more serious testing.
Now, I know I could just get rid of what's on the drive, get a new one and create a mirrored vdev right from the start, but that wouldn't be fun enough. I am planning on transforming the current striped vdev in a mirrored one (yes, I have read the info for noobs -> I know this is the only change to a vdev you are allowed to make :P ) to start with, just to add some redundancy, but this is what I haven't decided/understood yet:

- Suppose that in the future I buy two more drives, would it be better to create a new mirrored vdev inside the existing zpool, or to create it in a new zpool? Two different zpools would mean that even if both drives failed inside the same vdev, the other zpool would not be impacted (not true with the single zpool option), but I am looking for confirmation.
- Should I decide to want both performance and redundancy, should I
- a) stripe two mirrors
- b) mirror two stripes?
- Since the current HDD I am using was just a spare one, if I just begin with buying one new drive, it won't probably be the same brand/type, but only the same size. Would there be any catastrophic issues coming out from this configuration?
