Solution to this;
Stop calling NVMe’s SSDs, as they aren’t solid state, they are NVMe.
Solid State Drives are objectively are a description of the drive’s technology, just as Non-Volatile Memory Express is.
Likewise M.2 is an interface type, just like SATA, or IDE.

There’s also the older, slower eMMC storage still used on some lower-end laptops.

Excellent read and easy to follow for the average everyday person. I can easily choose the right drive for my needs after reading this. Thanks for writing!

M.2 is a form factor, NVMe is the protocol. You need to compare protocol against protocol, i.e. NVMe vs SATA and 2.5″ vs M.2

There’s already too many people who think “M.2 SSDs are faster”.

One other factor to consider is how many bits are stored per cell as in EVO (3 bits per cell) vs QVO (4 bits per cell) and how much slower QVO is compared to EVO. Fewer bits => faster, more reliable, more expensive. More bits -> slower, cheaper and less reliable
