Samsung 850 Evo 250GB M.2 SATA III 6Gb/s SSD

Overview

The Samsung MZ-N5E250BW is a 250GB solid state drive designed for systems using the M.2 SATA III 6Gb/s interface. It delivers fast sequential read speeds up to 540 MB/s and write speeds up to 500 MB/s, making it an excellent choice for improving boot times, application launches, and file transfers. Its compact form factor fits well in notebooks, ultrabooks, and desktops where space is limited but performance remains a priority.

Equipped with Samsung’s 3D V-NAND technology, this SSD offers enhanced storage density and durability compared to traditional NAND flash. The 512MB LPDDR3 DRAM cache supports smoother data handling, which benefits multitasking and working with large files. Additionally, the MGX controller optimizes power consumption, reducing it to just 2 mW during idle, helping extend battery life in portable devices.

Security is also a focus, with AES 256-bit hardware encryption and support for TCG Opal and IEEE1667 standards, protecting sensitive data effectively. Its mean time between failures rating of 1.5 million hours underscores its reliability for both everyday users and professionals.
