Let me start by saying that I have 4 copies of my data (7 TB-ish) so I’m hoping to rearrange drives on 2 of my NAS’s while at the same time upgrading to QuTS. The upgrade would be occurring on my TS-464 (currently has 2 8TB and 2 14TB, each in Raid 1) and drive swap with my TS-233 (2 8 TB drives). The plan is to move the two 14TB drives to the TS-233, increasing capacity and creating a set of four 8 TB drives for the TS-464. As ZFS will be new to me, how should I set up the four 8TB drives (Raid/ZFS type)? As I will have 3 additional copies of the data, flexibility is my main focus. I’d rather not lock myself into having to swap all 4 drives for an upgrade down the road. Please advise.
As you cannot move any data over from these units ARM vs x86 and QTS vs QuTS. You basically set everything up from scratch and restore from backups.
For the 4 disks in the 464, I would just use RAIDz (RAID5), plain and simple.

Thank you, I had read that some people in 4 drive configs created 2 mirrored vdevs with ZFS essentially creating a RAID 10. This allowed the disks to be upgraded in pairs instead of quads. Not sure if this is exactly true or if QuTS even allows this. In the RAIDz, I would have 24TB available so I don’t see myself upgrading any time soon anyways.
Thanks and yes I realize all disks would start from scratch. Any clue whether or not a QTS backup can be restored on QuTS or just start fresh and standard data sync?
Afaik, you have to replace all drives in QuTS to expand pools, so besides a 50% storage penalty, the RAID10 would do you not much good.
Unless you mean pairs of two to expand the drive count (but with 4 our of 4 bays used, this wouldn’t be the case either)

The default backup for QTS and QuTS is a plain file backup, you can restore them anywhere you like. If you are talking about snapshot recovery, those would not be intercompatible between QTS and QuTS
Thanks so much
