- Unraid is switching to annual subscription pricing, offering Starter, Unleashed, and Lifetime licenses with optional extension fees for updates.
- Existing Basic, Plus, and Pro licenses can be upgraded to higher levels of perpetual licenses.
- This change may increase revenue for Lime Technology but could also make other NAS providers more appealing to users.

Unraid uses a very simplistic scheme where you throw together a bunch of drives and one parity drive. The parity drive needs to be as big as the largest normal drive and holds recovery checksums for all the other.
Basically you can lose any one disk and still be able to recover the data, and the disks don’t have to be the same size.
You can achieve the same with snapraid + mergerfs if you want.
TrueNAS uses distributed parity schemes so it has same size requirements, but it also protects against bitrot and has other extra features.
