Can I use a Yottamaster 5-bay RAID hard drive enclosure?

This is my first time building a NAS (I have had a Netgear NAS for years now) and using the HexOS will negate me from having to learn all the intricacies of TrueNAS.

So my plan is to use a Beelink Mini S Pro 12 (with a Wavlink USB C to Ethernet Adapter 2.5 Gbps) and connect a Yottamaster PS500RU3 DAS to it via USB 3.0 and routed via my 2.5gb network.  I won't use the raid hardware on the enclosure, but instead use the HexOS to create a NAS that I would use mainly for backups and file storage.  Originally I plan on populating the NAS with 5 drives of various size I have laying around the house and as I can afford the them upgrade the 5 drives to 16TB each (the max size the DAS supports).  Since the current drives are not real large I can exchange each drive over time and have the NAS rebuild the missing drive, which based on the size shouldn't take too long from what I understand.

I hope that HexOS will also support Universal Media Player software in the future, but I suppose until it does I can have the Mini PC I use for my server right now just have it use the NAS as the location of the files.  I don't use Plex because it has become too much.  I just want to store photos and my movie library without having all the other stuff that Plex adds.  I don't need to stream outside movies and watch live TV, sports, etc.  I want to direct the server to my 2 or 3 libraries and that is it.  I have a smart TV's and Roku for the other stuff.  UMP also seems to run faster.  While my network is 2.5Gb the TV's are all only 1GB.  I hope that changes in the near future with either 2.5Gb or better yet skip to 5Gb's.

Does this seem realistic?

In general its not recommended to us external storage.
if plex is too bloated you can try jellyfin

1gb tvs are actually pretty good lol, most tvs i come across have 100mb nics

to the best of my knowledge rebuilding arrays are incredibly stressful for the remaining drives and doing it multiple times risk drive failure.

im actually not sure if hexos/truenas will automatically increase pool size if you replace the smallest drive with a bigger drive. it would be great if it does

***FAILED***

I tried the hard drive enclosure and HexOS would only see 1 drive of the 3.  I have seen posts from other users experiencing the same problem so I am assuming (Yes, I know the old Benny Hill bit) that the problem is with the USB connection and if I had a direct SATA connection for all of my drives there wouldn't be a problem.

Time to build a real NAS.

FYI - The 2.5gb USB lan connection worked flawlessly.
