Diy Nas Help

[Enquiries]

Hi

I'm looking to build my own nas and I have picked what parts to have, I'm just wanting to work out what's best in terms or Truenas or unraid.

My main concern is the data I have on my old terramaster nas, how best is it to get the data to the new system, will I be able to just plug the hard drive in and then either truenas or unraid will see it, don't really want to lose the data, its 2 hard drive 16tb each, If you can advise the what's best to do, was going to get another 16tb hard drive as well to add to the setup as well, as that's the reason I'm upgrading as both are nearly full.

Thanks
Peter

You're correct that Terramaster drives are typically tied to the brand’s specific configurations, so they might not be easily transferable to a new system unless it’s another Terramaster device. Unraid supports ZFS RAID migration from other brands, but that won't apply if your old drives aren’t in a compatible format.

In this case, you’ll need to format the drives when setting up your new NAS (whether with TrueNAS or Unraid). That means you’ll lose the data on those drives unless you have a backup.

Here’s what I recommend:

Backup the data: Before anything else, back up your data. You can use an external drive or cloud storage for this.

Prepare your new NAS: Set up your new system with your new drives, creating the desired file system (ZFS for TrueNAS or XFS/BTRFS for Unraid).

Move your old drives to the new NAS: Once your new setup is ready, you can migrate the data from your backup onto the new drives.

If you're adding a new 16TB drive, it’s a good idea to use that as part of your new storage array. Make sure your data is safe before wiping any drives.
