The 860 Pro is Samsung’s latest consumer-grade SATA SSD flagship, superseding the popular, but now three years old, 850 Pro. Like the 850 Pro, the 860 Pro is based on Samsung’s proprietary and revolutionary (at the time), MLC V-NAND (3D). A 10% price premium over the 256 GB 850 Pro will purchase the 256 GB 860 Pro which has an impressive 16% faster effective speed. This is achieved via an updated controller (MJX) and 64 layers of V-NAND (versus 32 layers per the 850 Pro). The 860 Pro has sequential speeds of up to 540 MB/s which almost completely saturate its SATA 3.0 interface. These peak levels of performance are slightly higher, but still comparable to the peak performance of the 860 Evo before its SLC write cache (12 GB on the 250 GB Evo) is saturated, making the 860 Evo (at around 30% cheaper) a more economical choice for users who rarely write more than 12 GB at a time. There are also reliability improvements compared to the 850 generation with Samsung now offering a warranty of 300 TBW (terabytes written) for the 256 GB 860 Pro, compared to 150 TBW for the 256 GB 850 Pro. Thanks to higher density NAND, the 860 Pro is also available in a 4 TB variant, whereas previously 2 TB was the largest capacity for a Samsung SATA MLC SSD.  [Feb '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]
