SAMSUNG 850 EVO M.2 Internal SSD, featuring big capacity and high reliability, experiencing high performance in heavy workloads and engineering applications, is specially designed for PCs and workstations, adopting Samsung V-NAND 32-layer architecture, matching with M.2 interface to provide you new-generation performance.

3D V-NAND Technology

Stacks 32 cell layers vertically resulting in higher density and better performance utilizing a smaller footprint. With higher density, better performance and space-saving.

Fast read/write speed

The write speeds is up to 520 MB/s with TurboWrite technology and the read speeds is up to 540 MB/s.

RAPID mode

Utilize unused PC memory (DRAM) as a high-speed cache and boost the data processing speed up to 2x faster.

Enhanced Endurance and Reliability

The performance is increased by 30%, and the total bytes written is double of 840 EVO.

AES 256-bit Encryption

Keep your data and personal files more safe.

Wide Compatibility

Suitable for different demands of many devices. Support Ultra-thin laptop or tablet.
