Because I like the size of the 2 bay unit. It suits my needs.
My experience with QNAP hardware has been generally positive, so I’m happy to keep using it.
The price is irrelevant: I’m not trying to prove I can make the same NAS only cheaper. But, as it turned out, this one was on-sale and came with a free RAM upgrade to 16GB.
And I don’t need the software bloat that is QTS.
Is that sufficient?
