Updated controller and TLC NAND for 560/530 MB/s read and write

Samsung has launched its latest addition to the SSD lineup, the 870 EVO, which pairs up TLC NAND with an updated controller in order to push the SATA interface to its limits, achieving 560MB/s read and 530MB/s write sequential performance.

Similar to the 870 QVO, released earlier, the new Samsung 870 EVO uses the Samsung MKX controller, which when paired up with 128L 3D TLC NAND should offer up to 38 percent performance improvement in random read performance compared to the 860 models, at least according to Samsung. Samsung also equipped the 870 EVO with variable SLC buffer, which allows its own Intelligent TurboWrite technology to maintain peak performance levels.

The Samsung 870 EVO comes in a standard 2.5-inch form-factor with a SATA 6Gbps interface and will be available in 250GB, 500GB, 1TB, 2TB, and 4TB capacities. The 250GB and 500GB models come with 512MB of LPDDR4 DRAM, 1TB has 1GB, 2TB model comes with 2GB, and the 4TB model comes with 4GB of DRAM cache.

All models are rated for peak sequential read and write performance of up to 560MB/s and 530MB/s, respectively, as well as 98K IOPS read and 88K IOPS write random performance.

As these are TLC-based SSDs, you are looking at write endurance ranging from 150TBW for the 500GB model to 2,400TBW on the 4TB one, or 0.3DWPD (driver write per day). All models are backed by a 5-year of warranty.

The price is set at $49.99 for the 250GB model, $79.99 for the 500GB model, $139.99 for the 1TB, $269.99 for the 2TB, and $529.99 for the 4TB model. Currently, only the 250GB, 500GB, and 1TB models are available at Amazon, but higher capacity models should be available soon as well.
