I use this combo for running a Parallels Windows VM and these are my speeds with Catalina on a 2020 iMac i9 27" with 64GB of RAM:



WD_BLACK 1TB SN750 NVMe Internal Gaming SSD Solid State Drive - Gen3 PCIe, M.2 2280, 3D NAND, Up to 3,470 MB/s - WDS100T3X0C

Thunderbolt 3 SSD Enclosure,Thunderbolt3 to NVME M.2 2280 Hard Drive Case Compatible with New M1 CPU

I haven't tested it with my MacBook Pro M1 Max 64GB yet.
