Samsung Electronics, the world’s largest maker of NAND flash memory, introduced its new Samsund SSD 840 Evo-series solid-state drives. The new SSDs are based on triple-level cell (TLC, 3bpc) NAND flash memory and provide up to 1TB capacities at reasonable prices.


The Samsung SSD 840 Evo line-up is available in five capacities: 120GB, 250GB, 500GB, 750GB, and 1TB. The new Samsung SSD 840 Evo line-up makes use of the 10nm-class 128Gb high-performance NAND flash memory, which Samsung began mass producing in April. With these chips and Samsung’s proprietary multi-core MEX controller, the Samsung SSD 840 Evo achieves unrivaled value for performance with improved sequential read and write speeds.

Compared with the 250GB 840-series SSD, the highest selling capacity of the 840 lineup, the new 250GB 840 Evo now delivers 520MB/s sequential write speed – making it more than two times faster than the previous generation. In the case of 120GB model, the 840 Evo achieves up to 410MB/s sequential write speed, which is approximately three times as fast as that of the 120GB 840 Series SSD.

For the 1TB 840 Evo SSD, the sequential read/write performance has reached 540MB/s and 520MB/s. Furthermore, both the random read and write performance have improved, reaching 98,000 IOPS (input output operations per second) and 90 000 IOPS, respectively. This significantly enhances the user’s real-world computing experience, especially when he or she is dealing with very large data files.

Samsung also significantly narrowed the capacity-induced differences in performance, which gives consumers a broader spectrum of devices to choose from, the company said.

“After accelerating the growth of the SSD market with last year’s launch of entry-level, high-performance SSDs, we are introducing much faster SSDs with up to 1TB capacities offering consumers a wider range of choices. Samsung continues to enhance its SSD brand image by delivering the industry’s highest quality solutions and continuously increasing its SSD market share by expanding the adoption of higher density SSDs especially in client PC segments,” said Young-Hyun Jun, executive vice president, memory sales & marketing, Samsung Electronics.
