Anyway, it turns out that M2/NVME -> 2.5" SATA adapters are non existent; every single M2->2.5 adapter I find is either for B or B+M key M2s (NGFF) and/or the have a SAS/U2 connector which I can't ...

This article explains the differences between NVMe, SATA, and M.2 SSDs, including form factors, interfaces, and protocols.

Typically for Intel, you're good, with AMD, m.2 and SATA are often sharing the same chipset PCIe lanes so you have to sacrifice some SATA ports to use m2. (SATA or NVMe, often doesn't matter).

Pretty much always If you're upgrading from a SATA SSD, it'll almost certainly be to an NVMe-based M2 SSD. It can significantly improve your system's performance, even for general tasks.

Interface type SSDs can either use NVMe or SATA as the method for communicating with the rest of a PC. SATA is slower than NVMe. M.2, on the other hand, is actually a type of form factor.

However, not all M.2 slots support NVMe (some only support SATA, some only NVMe, and some either), so even if you have an M.2 slot you'll need to double-check that yours will allow for an NVMe drive.

The 256GB Intel SSD 545s SATA drive was selling for $73.99, or $0.29/GB. The 256GB Intel SSD 760p NVMe drive sold for $81.99, or $0.32/GB.

SilverStone has unveiled a new external SSD enclosure that is capable of supporting both SATA and NVMe storage offering up to 10Gbps SuperSpeed transfer rates via a USB 3.2 Gen2 Type-C interface.

SATA 3 doubles it up, as such we get 6000 Mbit/s : 8 = 750 MB/s (again deduct overhead, tolerances, error-correction and random occurrences) of available bandwidth for your storage devices.

NVMe SSD boards are more common than SATA M.2 SSDs these days. Installing the SSD inside the Stand & Hub is simple, and the correct-sized screwdriver and screw are included.
