Samsung PM961 MZVLW256HEHP

The Samsung PM961 MZVLW256HEHP is a M.2 22x80 NVMe SSD with a rated capacity of 256 GB. The MZVLW256HEHP is officially EOL as of October 2019 according to Samsung's website.

The Samsung PM961 series is essentially a rebrand of Samsung 960 EVO series intended for use by OEMs.

Performance

The PM961 uses Samsung's very own Polaris contoller. The four PCI-Express 3.0 lanes allow for a transfer rate of up to 3938 MB/s, seven times the performance of the outdated SATA III link.

The rated sequential read and write speeds are at 2800 and 1100 MB/s, respectively. While these were not confirmed in our independent testing with CrystalDiskMark 3, the PM961 is still a very good SSD - more than adequate for the vast majority of tasks including both content creation and consumption.

... The 256 GB drive is addressed using PCIe, so the transfer speeds are significantly faster than they would be with a SATA interface - Lenovo Legion Y720 Laptop Review | May 2017
