Samsung 850 PRO Series 512GB 2.5" SATA III SSD

The Samsung MZ-7KE512BW is a 512 GB solid-state drive that fits into a standard 2.5 inch bay and connects through the SATA III interface. Built with Samsung 3D V-NAND flash memory arranged in thirty-two layers, it reaches sequential read speeds up to 550 MB/s and sequential write speeds up to 520 MB/s.

Random access performance is equally impressive, hitting 100,000 IOPS for reads and 90,000 IOPS for writes. Everyday tasks such as booting an operating system, loading large creative projects, or starting a game level feel almost instantaneous compared with a traditional hard drive.

When you enable RAPID mode through Samsung Magician software, the drive borrows a small portion of system DRAM to act as an extra cache. The result is even quicker response during heavy multitasking or large file transfers, without the need for additional hardware.

Security is handled on the drive itself through hardware-based AES 256-bit encryption that meets TCG Opal 2.0 guidelines. Dynamic Thermal Guard monitors temperature in real time and adjusts operations to keep the drive within safe limits, preserving both performance and longevity.

The 850 PRO draws just 3.3 W under active load and a negligible 2 mW in standby, making it a strong choice for battery-sensitive laptops. With an endurance rating of 150 TBW and a ten-year limited warranty, it offers dependable storage for gaming rigs, content creation workstations, and business systems that need consistent speed and long-term reliability.
