The Samsung 860 (either Evo or Pro) is a SATA3 SSD and as such as a maximum throughput of 6Gb/sec. Thunderbolt 2 has a maximum throughput of 20Gb/sec. So theoretically, you won't have any performance gain in getting a Thunderbolt 3 enclosure. In order to connect a Thunderbolt 2 device to the 2018 Mini, you would need a TB3->TB2 adapter and I don't know if there is a performance slowdown due to that conversion but if there is, it's not a major one. If you're going to spend the money to buy a Thunderbolt 3 enclosure that supports a single SATA3 device just for the extra performance (if there actually is a difference), you would be better off buying a whole new device which has a PCIe NVMe SSD.

The Samsung 860 maxes out at around 500 MB/s so you definitely do not need thunderbolt 3. Any USB 3.0 or USB C 3.0 enclosure with SATA m.2 will be fine.
