If only they weren't overpriced...

as a customer (8-bay) they also cut down the quality in recent products, my old nearly all metal QNAP was near silent, the new enclosures are all plastic and you hear the drives noticeably more I dropped it and made my own server after watching a Linus video, it's much larger but also better

you can make such a better NAS by building it yourself. These prebuilt ones are always so over priced.
