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 Intel Optane SSD 900P series are the first consumer grade NVMe PCIe SSDs available using Optane memory. This is a new class of memory based on new 3D XPoint lithography. The 280 GB version is available in either a U.2 15mm or half height half length add-in card form, both with a PCIe 3.0 x 4 interface. A 480 GB version is also available. The impressive benchmarks from this SSD (sequential read speeds of 2500 MB/s and sequential write of 2000 MB/s) are consistent with Intel’s reported specifications. The 280GB 900P is about 10% faster at sequential read/write than the next best NVMe PCIe flash based SSD, the Samsung 960 Pro. However, the 280 GB 900P really excels at random 4K reads and writes. Specifically, it is about 4 times faster than the 960 Pro at random 4K reads. Since on average, about 50% of typical consumer disk access is sequential reads or writes, the full benefits of the 280GB 900P may not be relevant for all users. Early access to this new technology comes at a premium, the 280GB 900P costs approximately twice as much per gigabyte compared to the 960 Pro. These drawbacks will no doubt influence the mass adoption of this class of memory in its infant stage. However, it is no less exciting for the industry and is indicative of the speeds that we can expect to achieve as standard in the future. [Nov '17 SSDrivePro]
