Samsung’s NVMe SSD flagship, the 960 Pro, is one of the fastest consumer SSDs on the market, currently second only to Intel’s 900P Optane SSDs. This PCIe SSD offers high-end performance at a premium price and therefore, as the name suggests, is may be more suited towards professional users. Our real world benchmarks show that the 960 Pro has read/write speeds in excess of 4 times faster than the Samsung 850 Pro which is the next best SATA SSD. Compared to the now two year old NVMe 950 Pro the 960 Pro offers significantly higher write throughput and is less susceptible to thermal throttling. The 960 Pro is based on a denser version of Samsung’s V-NAND (3D) technology, featuring more layers of memory cells. The 960 Pro also features an upgraded and faster 5 ARM Polaris controller, compared to the 950 Pro’s 3 ARM UBX controller. The smallest capacity for the 960 Pro is 512 GB, which may make it prohibitively expensive for some. Fortunately, for those that still want the superb NVMe performance, the 250 GB Samsung 960 Evo offers a more affordable choice, albeit with lower sustained write speeds when compared to the 512 GB 960 Pro. The 960 Pro is based on MLC (2-bit) V-NAND whilst the 960 Evo is based on the slightly lower enduring TLC (3-bit) V-NAND, and this accounts for Samsung’s reduced warranty for the 960 Evo (3 years/200 TBW versus 5 years/400 TBW for the 512 GB versions of the 960 Evo and 960 Pro respectively). Unlike the 960 Evo, the 960 Pro doesn’t have an SLC cache which results in more consistent sustained write speeds. [Nov '17 SSDrivePro]

The 960 Evo SSD is one of Samsung’s premier NVMe SSDs, along with their current flagship, the 960 Pro. The Evo variant is available in a variety of capacities including 250, 500 and 1000 GB, each with a commensurate price tag, whilst the 960 Pro is available in 512, 1024 and 2048 GB capacities. The 960 Evo has lower write endurance compared to the 960 Pro due to its TLC (3-bit) V-NAND flash memory (the 960 Pro consists of MLC (2-bit) V-NAND). As a result, Samsung only guarantee 200 terabytes written on the 512 GB 960 Evo, compared to double that on the 960 Pro, however, this volume of data is very unlikely to affect consumers. The 250 GB 960 Evo has a 13 GB SLC cache which boosts initial write speed to roughly match the 960 Pro but writes exceeding 13 GB drop in speed by over 50%. Overall, the 960 Pro offers more consistent write performance than the 960 Evo, however, this will only impact workloads that exceed the 13 GB. [Nov '17 SSDrivePro]
