Samsung PM951 NVMe 512 GB

The Samsung PM951 is a PCIe (NVMe) based solid state drive with a capacity of 512 GB. It is an M.2 22x80 type drive designed primarily with laptops in mind. As of Q1 2020, the SSD's perfomance roughly corresponds to the budget segment of modern solid state memory.

Notebookcheck says:

... The 512 GB NVMe Samsung PM951 SSD easily outperforms SATA III-based SSDs on older notebooks and even some newer ones that have yet to make the transition to the newer controller or have decided to cut back on the feature - Dell XPS 13 9350 Laptop Review | February 2016
