— Crucial’s BX300 SSD is a 3D MLC entry level SSD, with debut pricing in line with the Samsung's 850 Evo, the current market leader. The BX300 is the fastest consumer MLC SSD available, with a 2% performance improvement over Crucial’s older MLC based MX200 and a 25% performance improvement over the TLC based MX300 which are both from Crucial’s more expensive MX product line. MLC NAND offers more consistent performance and has higher endurance than TLC NAND. Although Samsung’s 850 Evo (which is based on proprietary TLC V-NAND) has a 10% effective speed advantage over the BX300 the BX300 wins on write consistency. The 240GB BX300 has a three year warranty or 80 Terabytes Written (TBW) compared to five years or 75 (TBW) for the 250 GB 850 Evo. This makes for an interesting choice between the BX300 and the 850 Evo. Each model has an SLC cache which is proportional to its capacity, as a result the larger capacities offer better performance. The 120 GB BX300 has a 4 GB SLC cache, the 240 GB has 8 GB and the 480 GB has 16 GB. SLC caches improve burst write performance beyond the already respectable MLC write performance. Unfortunately, at least for now, the BX300 only comes in modest capacities, with the largest being 480 GB. For write consistency, thanks to its MLC NAND, the BX300 punches well above its price point.

— 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.

— 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.

— 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.

— 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.
