Samsung 870 EVO 1TB SATA SSD

The Samsung 870 EVO is a 1TB 2.5-inch internal solid-state drive that uses V-NAND memory and a SATA III interface. It is built for consumers who want a straightforward storage upgrade for a desktop PC or laptop without changing platform architecture. A 1GB cache and AES 256-bit hardware encryption with TCG Opal 2.0 and IEEE 1667 support are included.

Fits standard 2.5-inch SATA bays

The drive slides into any standard 2.5-inch SATA bay and connects with the existing SATA data and power cables, so no adapter brackets or new cables are required. Its low idle draw of 30 mW and average active consumption of 2.5 W leave more headroom for other components in a laptop power budget. Compatibility testing covers major chipsets, motherboards, NAS units and video recording devices, reducing integration risk.

Sustained write performance

The 870 EVO maximises the SATA interface limit with sequential speeds up to 560 MB/s read and 530 MB/s write, and a larger variable buffer helps maintain those rates during long transfers. Endurance is rated at 600 TBW with an MTBF of 1,500,000 hours, indicating consistent behaviour under heavy workloads such as 8K video processing. Active power peaks at 4.0 W and shock resistance is rated at 1500 G for physical durability.
