Samsung Officially Announces 870 EVO SATA SSD Series

By January 21, 2021 News No Comments

Samsung today has officially taken the lid off their latest consumer-oriented SATA SSDs, the 870 EVO. The 870 EVO series from Samsung don’t push the maximum storage density ceiling on traditional SATA consumer drives, topping out at a maximum 4 TB, but they do achieve that ceiling whilst making use of Samsung’s 128-layer TLC (Triple-Layer-Cell) NAND, which offers increased endurance (and higher theoretical performance than) more widespread QLC-based SSDs (of which Samsung launched the 870 QVO back in July 2020).

Samsung quotes SATA sequential read and write speeds of 560 MB/s and 530 MB/s respectively, with a “variable SLC” cache (which means it decreases in maximum size as the available free drive space decreases). The drives are also quoted at 98K IOPS Random Read, and 88K IOPS Write, and feature the company’s Intelligent TurboWrite to maintain the interface’s SATA 6 Gbps saturation as long as possible before sustained performance degradation appears. Samsung claims the 870 EVO also delivers a nearly 38% improvement in random read speeds over the previous 860 model, and quotes a (TBW) rating of 2,400 TB (or a 5-year limited warranty, whichever comes first) for its 4 TB model.

The 870 EVO is available in either 256 GB, 512 GB, 1 TB, 2 TB, or 4 TB capacities, with the drives’ RAM buffer scaling almost accordingly (512 MB DDR3 for the 256/512 Gb models, 1 GB for the 1 TB, 2 GB for the 2 TB drive, and 4 GB for the 4 TB one.
