Samsung 850 PRO Series 256GB 2.5" 520 MB/s SATA III SSD

The Samsung MZ-7KE256BW is a 256 gigabyte solid-state drive that installs in any system with a standard 2.5 inch SATA bay. Built with Samsung 3D V-NAND technology, it offers sequential read speeds up to 550 megabytes per second and write speeds up to 520 megabytes per second, delivering a clear jump in responsiveness over mechanical hard drives and many earlier-generation SSDs.

Inside, the drive combines 32 vertically stacked memory layers with an LPDDR2 cache that lowers active power draw. For workloads that demand quick access to many small files, it reaches up to 100 thousand input output operations per second on reads and 90 thousand on writes. A built-in thermal guard monitors temperature and adjusts performance when necessary to help maintain reliability under long gaming sessions or large file transfers.

Security features are handled at the hardware level through AES 256 bit encryption, with full support for TCG Opal 2.0 and IEEE 1667. This lets business users enable self-encrypting drive policies without sacrificing speed. When battery life matters, a 2 milliwatt device sleep mode keeps standby consumption extremely low.

The drive ships with Samsung Data Migration and Magician utilities, so moving an existing operating system, applications, and files is straightforward even for first-time upgraders. Once installed, the firmware can enable RAPID mode, which uses available system memory as an advanced cache to push everyday performance even further.

Whether you want faster boot times on a travel laptop, shorter level loads in a gaming rig, or a reliable scratch disk for video editing on a desktop workstation, this SSD brings a blend of speed, efficiency, and endurance. Samsung rates it for 150 terabytes written and backs it with a ten-year limited warranty, making it a long-term storage solution for both home and professional environments.
