Samsung 850 EVO M.2 500GB SATA SSD

The Samsung 850 EVO M.2 2280 delivers 500GB of storage through a SATA interface for ultra-thin laptops and PCs. It uses 3D V-NAND technology and a Samsung MGX controller with 1GB of low power DDR3 cache. Sequential reads reach 540 MBps and writes reach 500 MBps. Random performance hits 97,000 read IOPS and 89,000 write IOPS.

Thermals noise and power efficiency

The drive operates from 0°C to 70°C with no moving parts, so it runs silently. The 3D V-NAND architecture lowers power draw compared with planar NAND, supporting industry-leading energy efficiency. MTBF is rated at 1,500,000 hours and shock resistance reaches 1,500G for physical durability.

Upgrade from hard drives or early SSDs

Replacing a mechanical hard drive with this SSD cuts boot and load times dramatically thanks to SATA III speeds and high random IOPS. The jump is worth it when you need faster large-file transfers, full-disk AES 256-bit encryption, and reliable operation in thin chassis. Samsung Data Migration and Magician software simplify the switch.
