Samsung 850 EVO Series 250GB TLC SATA Internal Solid State Drive SSD

Samsung 850 EVO SSD

The Samsung 850 EVO internal solid state ssd is the most recent in its affordable line of execution SSDs and shows Samsung’s longing to push the strong state game along, even at the lower end of the value/performance stack.

The combination of hardware and firmware tuning gives the SSD 850 EVO pretty impressive sequential read and write speeds across all capacities, with 540MB/s and 520MB/s respectively. This is up from 44TBW in the 840 EVO, a direct benefit of the move to 3D V‐NAND Flash which allows for greater endurance. The SATA interface on this drive is generally used for consumer desktops, data backups, and other less demanding roles. Carries an MLC (Multi-level cell) flash memory technology, capable of storing more than a single bit of information per memory element.

The 850 EVO uses a Samsung MGX controller (2-core) with the 120GB, 250GB, and 500GB capacities while the 1TB uses the Samsung MEX controller (3-core). The storage derives from the drive’s use of Samsung’s 32layer TLC 3D V‐NAND LPDDR2 for the DRAM Cache. The Samsung SSD 850 EVO uses a SATA 6Gb/s interface, though it is also compatible with SATA 3Gb/s and SATA 1.5Gb/s.

The SSD 850 EVO continues Samsung’s trend of developing class-leading and innovative SSDs by improving on the 840 EVO on virtually every level using the company’s latest software and hardware technologies.

Overall, the Samsung 850 EVO is an incredibly impressive drive with bar-setting performance, a solid design, and Samsung reliability. The 850 EVO is so good in fact, it even topped the 850 PRO in many areas.
