Maybe I'm out of the loop but I've never heard of "Topton". As this brand is being mentioned 16 times in this one blog post I'm just assuming that's a sponsored blog post and not an objective overview.

Every time I've looked into doing a DIY NAS in the last few years Topton seems to come up - as far as I can tell it's because they make MiniITX boards with a boatload of SATA ports.

Topton makes a lot of those router mini PCs. I have an N100 with 4 2.5Gbe ports. It has a serial port too, which is nice. It's been running great for about a year now. Then again, it's from Aliexpress, so who knows if it's even really a Topton.
