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 480 GB Intel Optane 900P is one of the first NVMe PCIe SSDs available, based on Intel’s new Optane memory and 3D XPoint technology. 280GB versions are also available with almost identical performance at a lower price, in line with the reduced capacity. The 480 GB 900P is comes in a half height half length add-in card form and has a PCIe 3.0 x 4 interface. The sequential read and write speeds of 2500 MB/s and 2000 MB/s are the fastest of any consumer SSD on the market today, however this is only 10% ahead of the next best NVMe PCIe SSD based on flash technology, the Samsung 960 Pro. The random 4K read and write speed disparities are far greater, with the 480 GB 900P achieving a whopping four times faster random 4K read speeds than for the 960 Pro. If memory usage is heavily skewed towards random 4K reading, then shifting to the 900P would yield a huge performance boost worthy of the 900P’s high price tag. Access to this latest technology comes at double the cost per gigabyte compared to the 960 Pro. Currently the PCIe interface will be a bottleneck for even greater performance. However, it’s early days for Optane memory and it’s likely that Intel will release higher performing devices in the future as faster bus technologies emerge. [Nov '17 SSDrivePro]
