Samsung SM961 MZVKW512HMJP m.2 PCI-e

The Samsung SM961 MZVKW512HMJP is a M.2 22x80 SSD with a rated capacity of 512 GB. It relies on the modern PCIe 3.0 x4 (NVMe 1.2) interface for data transfer. The drive is based on 2-bit MLC memory paired with Samsung's very own Polaris controller.

Performance

The rated sequential read and write rates are at 3200 and 1700 MB/s, respectively. These were not confirmed in our independent testing with CrystalDiskMark 3. Still, the performance is good enough for any activities including content creation and gaming.
