The 970 Evo is Samsung’s third generation NVMe PCIe SSD for high-end consumers and professionals alike. It employs the latest Samsung Phoenix controller and their latest version of TLC 3D NAND (now 64-layers) which is cheaper but with slightly lower endurance and weaker write consistency than the MLC NAND found in the 970 Pro. The 970 Evo comes in a M.2 form factor and four sizes: 250GB, 500GB, 1TB and 2TB. The $120 250GB 970 Evo has an advertised sequential read speed of up to 3400 MB/s (200MB/s faster than the 250GB 960 Evo) and a sequential write speed of 1500 MB/s which drops to 300 MB/s once the 13Gb of SLC cache has been exhausted (this is similar to the sustained write performance on the 960 Evo). Further benchmarks are required before we can attest to its overall performance in the real world. The anticipated modest performance improvement between generations is expected to maintain Samsung’s front running as the premium SSD brand. Samsung now offers a warranty of 5 years across the suite of 970 SSDs and specifically a generous write endurance of 150 TBW on the 250 GB 970 Evo, thereby challenging the need for the 970 Pro MLC variant. [May '18 SSDrivePro]


Adata’s XPG SX8200 offers NVMe PCIe SSD performance at SATA SSD prices, thereby offering outstanding value for money to casual and power PC users alike. Adata have combined two high performance commodity components: a Silicon Motion controller (SM2262) and Micron’s second generation 3D TLC 64 layer flash memory. The XPG SX8200 also includes a generous SLC cache and a DRAM cache buffer. Adata have not specified the exact size of the SLC cache in each model but it’s clear from our 60 second sustained write tests that the buffer is sufficient for more than 60 seconds of continuous writes which equates to over 60GB (60s x 1 GB/s) for the 240GB model and over 90GB (60s x 1.5 GB/s) for the 480GB and 960GB models. Unlike many other drives with SLC caching, the SX8200 has a large enough cache to ensure that consumers will almost always operate the drive within the cache and therefore experience no write degradation at all. Adata offer a 5 year warranty and a limited TBW warranty (160 TBW for the 240 GB version, 320 TBW for the 480GB and 640 TBW for the 960GB) on these SSDs, which is in line with other premium manufacturers. The NVMe PCIe SSD consumer market has been dominated by Samsung in recent years but the 240GB SX8200 beats Samsung’s 250GB 970 Evo hands down on both price and performance (the 250GB 970 Evo is let down by a relatively small SLC cache which allows for less than 10 seconds of writes before saturation after which the write speed on the Evo drops to mere sub SATA 300 MB/s). The SX8200 is the new value leader and heralds a new era of competition for the mainstream segment of the NVMe SSD market. [Jul '18 SSDrivePro]
