Introducing The Samsung SSD 960 Pro
Since the initial announcement, the enthusiast community has been chomping at the bit for these drives. Thankfully, today, we can put Samsung’s performance claims to the test. We’ve got a 1TB Samsung SSD 960 Pro in house and have run it through a series of benchmarks, alongside some of the best NVMe-based solid state drives currently on the market. The SSD 960 Pro’s specifications portend a dominant performance, but we’ll lay all the numbers out and take a look, on the pages ahead...

All of the drives in the Samsung SSD 960 Pro series feature new 3rd Generation, 48-layer 2-bit MLC V-NAND (256Gb) Flash and a new Polaris controller, which has a native PCIe gen 3 interface and supports the NVMe 1.2 protocol. Samsung claims the SSD 960 Pro can outrun its predecessor -- the SSD 950 PRO -- by more than 40% for sequential reads and 300% for random writes.
Samsung warranties the SSD 960 Pro drives for 5 years and they have relatively high endurance ratings as well (up to 1.2PBW). The drives also have built-in thermal protection, which is to say they’ll throttle to protect the NAND and controller if temperatures get too high, but this too has been improved over the previous generation. The Samsung SSD 960 Pro features a new heat-spreader design that can dissipate heat more efficiently during heavy workloads. The heat-spreader is essentially just a thin copper film, but between that and the new 4-landing design used on the drives, which also improves thermal characteristics, heat is radiated across a wider area.
All told, the Samsung SSD 960 Pro series offers better endurance, enhanced thermal characteristics, and increased bandwidth over its predecessors.
