The Zike Z666 is the first of a new generation of enclosures for M.2 NVMe drives. It is tool-less, i.e. uses no screws, and supports Thunderbolt4/USB4 via new-for-2023 ASMedia ASM2464PD controller. It supports PCIe Gen4 x4 natively for faster transfers. (The Zike enclosure also accepts PCIe Gen3 SSDs.)
The Lexar NM470 SSD is an inexpensive PCIe Gen4 x4 SSD that is quite speedy. It costs less because it has no DRAM cache. (Faster drives of the same capacity with 4GB DRAM cache on board cost about $100 more.)
(The old standard was PCIe Gen3 which operates at half the transfer rate of Gen4. An even older standard, used for hard drives, is SATA. PCIe Gen3 is four times faster than SATA.)
The Zike drive is made of aluminum, a good heat sink, and has a plastic cover to protect its finish. There is a thermal pad (blue protective sheet) to help conduct heat away from the SSD. This is important as SSDs get much hotter than HDs, and they slow if they get hot. On the bright side, the Lexar is DRAM cache-less, so it draws less power, less than 1W when idle, and perhaps around 5W when busy.
Slide the M.2 card in and turn the grey rubber plug to hold the end of the SSD down.
Unpeel the blue protective film from the thermal pad and close the drive.
Plug the drive in. The cable is extremely short.
You should see this pop-up. Hit Initialize and Disk Utility will start.

The MacBook Pro M1 Max reports the connection as being up to 40Gb/s

Note the M1 MacBook Pro supports Thunderbolt 4 and USB4 (40 Gb/s), but does not support USB 3.1 Gen2 (10 Gb/s) or USB 3.2 Gen 2x2 (20 Gb/s), only slow 5 Gb/s with regular USB3. So one can only get 40 Gb/s or 5 Gb/s but nothing between.
Copying data from a HD initially to the SSD is, of course, slow and limited by the speed of the HD. A score of about 120 MB/s is about right for a 5400 rpm 5TB drive. So it can take hours to initially populate the SSD.
The free Blackmagicdesign Disk Speed Test reveals a speed close to 24 Gb/s (3000 MB/s).

Sequential read/writess are significantly slower than the built-in drive, but random reads/writes seems to outperform the built-in drive to my surprise!
Mac Fans Control shows 60°C. Maybe I should remove the plastic surround?
