So when is TPU going to invest in a multi-gig switch? It's a bit moot reviewing a 2.5Gbps NAS on a Gigabit connection.
QNAP has some very affordable options, they might even send you one for review if you ask them nicely.
This looks like a perfect fit, as the eight port switch is all 2.5Gbps.

The easy to use OS could be OMV. It's easy to install, to configure and to install dockers. In less than 2 hours you can have a NAS ready to use with some good plugins.
I've been running OMV for a few years. I also worked at QNAP at one point in time. The two compare poorly in terms of overall look and feel, but surprisingly there isn't too much disparity in terms of functionality, especially after support for Portainer was added to OMV.
I would say that the retail NAS guys have a lot more spit and polish with regards to their UI, but they also have a lot of nasty bugs and old, bad code lurking. Here OMV wins hands down, as it's based on Debian, so OMV would only suffer if Debian suffers from problems.
Yes, some things are a tad convoluted in OMV and takes some figuring out, but for a free NAS OS, it's overall quite easy to use.
