Capacity and interface

The Samsung 860 Pro MZ-76P512BW is a 512GB internal solid state drive with a 2.5 inch form factor and a SATA interface. It uses V-NAND 2-bit MLC memory and a Samsung MJX controller. The drive is intended for consumer workloads such as everyday computing, 4K video rendering and 3D data handling.

Sustained write behaviour

Sequential write speed reaches up to 530 MBps while sequential read reaches up to 560 MBps. Random write performance at queue depth 32 is rated up to 90,000 IOPS and random read at the same depth up to 100,000 IOPS. The 2-bit MLC architecture helps maintain consistent throughput during extended write sessions rather than throttling after a short burst.

Power and thermal profile

Average active power consumption is 2.0W with a burst maximum of 4.0W. The operating temperature range spans 0°C to 70°C and the drive carries a 1,500,000 hour MTBF rating. AES 256-bit hardware encryption compliant with TCG Opal and IEEE 1667 secures data without adding measurable thermal load.

Questions about this item

How much power does the 860 Pro 512GB draw during sustained all-day operation?

The drive averages 2.0W in active use and peaks at 4.0W in burst mode, with an operating range of 0°C to 70°C.

Does the 860 Pro 512GB include the SATA data cable and mounting screws needed for installation?

The box contains only the 2.5-inch 7mm drive and a user manual; cables, screws and brackets are not included.

Will the 860 Pro 512GB work in a laptop that only supports SATA II 3Gb/s?

Yes, the SATA III interface is backward compatible with SATA II ports, though sequential speeds will be limited to the slower link.
