FWIW - there were a couple years before the interface switched to NVMe standards that a lot of laptops, and some desktop motherboards, had the M.2 form factor with only SATA 3 interface, including the Dell 7559 which has been on Woot often enough. For those machines, these drives might fill a need.
Search for NVMe vs. SATA to get more info, here is 1st decent hit: https://www.online-tech-tips.com/computer-tips/sata-3-vs-m-2-vs-nvme-overview-and-comparison/
If you don’t NEED TAA compliant drives, I’d look elsewhere. These have a premium price tag because of the TAA compliant manufacturing. But for the price of these, you can gets halfway decent NVMe drives at the same capacity with 3-5x the speed.
Edit: case in point, an Adata SX8200 pro, 512gb is $79.99 at the mothership, and it performs outstandingly for its price, competing with or beating the Samsung 970 evos in some benchmarks.ADATA SX8200 pro
Or microcenter sells the Inland Premium brand (also on mothership through microcenter) 1TB is $129, and its speed are rated pretty high
I bought a 2TB and 1TB inland premium from mothership, since they have better shipping turnaround times than microcenter right now
