QNAP TS-251B vs Synology DiskStation DS119j (2019)

Analysis:

The QNAP TS-251B is a relatively good Home NAS for people that are willing to spend around $450. The Synology DiskStation DS119j, by contrast, is quite unremarkable and doesn't stand out in any meaningful way from other products at this price point.

In both cases, however, we recommend that you take look at some other options at the $450 and $160 budget ranges; in all likelihood you'll find some better alternatives.
