Samsung PM961 NVMe MZVLW512HMJP MZVLW512HMJP

The Samsung PM961 MZVLW512HMJP is a compact M.2 22x80 SSD with a rated capacity of 512 GB. The model is EOL as of July 2019 according to the Samsung website.

Architecture

The PM961 utilizes Samsung's 48-layer TLC V-NAND chips with LPDDR3 cache. It comes in capacities of 128 GB, 256 GB, 512 GB, 1024 GB. The TurboWrite technology is designed to reduce wear while Samsung's very own Polaris controller ensures both high performance and long-term reliability.

Performance

The PM961 relies on the modern NVMe (PCIe 3.0 x4) interface for data transfer. Four PCI-Express 3.0 lanes allow for a transfer rate of up to 3938 MB/s, seven times the performance of the outdated SATA III link.

While our testing did not confirm the 512 GB PM961's rated read and write speeds of 2800 MB/s and 1600 MB/s, respectively, it is still an excellent drive that can give its competitors a run for their money.
