Good Combo? Daisy Chain Port?

I just ordered the following from Amazon:

1. Super Thunderbolt 3 Dock for Mac Studio&Mac Mini, Dock Station with NVMe/SATA Slot(Up to 2800Mbps),4X USB 3.1 Port(10Gbps) , CFexpress/TF/SD Card Readers,Support Daisy Chain (up to 5 Unit) (Silver)

2. SAMSUNG 980 PRO SSD 2TB PCIe NVMe Gen 4 Gaming M.2 Internal Solid State Hard Drive Memory Card, Maximum Speed, Thermal Control, MZ-V8P2T0B

3. SAMSUNG 870 EVO SATA III SSD 1TB 2.5” Internal Solid State Hard Drive, Upgrade PC or Laptop Memory and Storage for IT Pros, Creators, Everyday Users, MZ-77E1T0B/AM

after looking at the compatibility grid that was posted here.

I plan on using it with an M1 Mac Mini. Does this look like a good combo for performance and reliability?

Also, the manual say that that one of the Thunderbolt 3 ports is for the uplink to the Mac Mini and the other is to daisy chain other docks. However, can you just use that as a regular Thunderbolt 3 port for anything you want?

Thanks

Carl
