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 '17SSDrivePro]
The MX500 is Crucial’s current flagship consumer SATA SSD featuring their latest second generation 64-layer 3D TLC NAND. It’s available in 250 GB, 500 GB, 1 TB and 2 TB capacities in a 2.5-inch form factor. All but the 2 TB version will also be available in M.2 (2280) form in the future. The MX500 features a Silicon Motion SM2258 controller which is a change from the Marvell 88SS1074 controller featured in the MX300 (it’s nearly two year old predecessor). Performance is around 30% better than on the MX300 which currently retails at the same price. The MX500 has an SLC cache which increases with drive capacity. Consequently, the larger capacities are better able to sustain high sequential write speeds. The 250 GB version has 250MB of SLC cache, the 500 GB has 512 MB, the 1 TB has 1 GB and the 2 TB has 2 GB. Extended sustained write performance tests show that even though speed does drop off after the cache has been exhausted, it is still maintained at very respectable levels. The MX500’s five year warranty is in line with Samsung’s 850 Evo and exceeds it in terms of endurance (just 75 TBW for the 250 GB 850 Evo versus 100 TBW for the 250 GB MX500). It doesn’t quite match up to the Samsung’s 850 Evo’s performance (effective speed 8% slower), however at current prices it is about 20% cheaper, and on balance offers better value for money.
