Samsung 870 Evo maximizes the potential of SATA SSD

Samsung has announced the launch of a new generation of solid-state drives connected to the SATA interface, which the South Korean giant describes as a “compelling combination of performance, reliability, and compatibility”.

The Samsung 870 Evo is, as we told you before, SATA III (6Gbps) storage drives designed to cover the entry-level segment. They have a 2.5-inch format with 7 mm thickness and can be used in both laptops and desktops. Also, you can reach the company’s announced from the following link.

Samsung mentions a 30% performance increase over the series it replaces, the 860 Evo, reaching speeds of 560 / 530 Mbytes per second in sequential read/write and a rating of 98K and 88K in 4K random read/write.

The performance increase, already at the limit of what the SATA interface can offer, is achieved with a new controller, new 3-bit V-NAND TLC memories, TurboWrite technology, and an additional data cache composed of LPDDR4 memory with variable capacity depending on the version, from 512 Mbytes to 4 Gbytes of the superior model.

Samsung 870 Evo models and prices

Samsung markets these units in storage capacities of up to 4TB at the following prices:

  • 250GB: $49
  • 500GB: $79
  • 1TB: $139
  • 2TB: $269
  • 4TB: $529

They will be available this month in the international market with a five-year warranty and a resistance in Tbytes written from 150 TBW of the smallest unit to 2,400 TBW of the 4 Tbytes.

You know that from here we have been recommending as a future format the PCI-Express units (ideally the new and faster 4.0) as the newest SSD 980 PRO from Samsung that we had the opportunity to analyze. However, not all users have motherboards that support them and the presence of SATA is still the majority.

Hence the interest that manufacturers continue improving this type of format that even with lower performance provides greater compatibility and better prices per GB than PCIe. Under this format, Samsung also has in the market the 870 QVO, drives that stand out for the use of the second generation of four-bit per cell QLC memory and storage capacities of up to 8 Tbytes.
