I've been using 3 of the startech branded docks for a few years now of basically constant use.(one up to 6 years I believe now)
One problem with these docking stations is that they are constantly ripped off/cloned so its hard to find anything that might be good...
A quick search on amazon proves this as you will find like 10 items that all look the same with different brand names.
The ones I have dont look like its being sold anymore, casing is all different, but who knows what the internals are like...

As the above one isnt the one I have, theres no way I can recommend this particular one, it looks similar but as i said above, who knows whats inside.
A lot of people (myself included to a degree) hate on the startech brand. but they are unavoidable in certain use cases. And the price is cheap enough to not care to much if it fails after a few years. However non of mine have failed, I also have another 6 sata to usb devices from them (not docks) which I must've bought at least 9+ years ago and they all still work and are still in use.... same with the drives i bought at the time as well for the most part!
Take that all with a pinch of salt, my experience won't be what others have had and might not be what you have if you buy one.

Slow. Instead something like this: https://www.amazon.com/StarTech-com-Docking-Station-3-5-Inch-SDOCK2U33EB/dp/B00KILQOG0 and put in two 6TB drives. Then implement disk rotation for airgapped backups.
I bought this HDD dock from Startech. It has eSATA but would not be recognized by my DS718+.
My NUC (Ubuntu server) picked it up without a problem.
