I have an old QNAP and I hate it. It’s full of proprietary software that can’t be removed, and is slow, probably because it doesn’t have SSDs. It’s, I think, RAID1.
Basically just need something to back up my data on my local network that has encryption. Open source is always nice as well. Simple and fast!
I just got a cheap Beelink minipc and slapped external HDDs on it — comes with a decent SSD inside and a slot for SATAIII drive inside too.
I’m running Debian on it, but FreeNAS/TrueNAS Community would have worked as well.
