860 Pro 256GB SATA SSD

The Samsung 860 Pro 256GB is a 2.5 inch internal solid state drive built for consumer workloads. It uses V-NAND 2-bit MLC memory and a Samsung MJX controller to deliver consistent performance for everyday computing and professional tasks such as 4K video editing and 3D data handling. The drive includes AES 256-bit hardware encryption compliant with TCG Opal and IEEE 1667 standards.

SATA III interface limits

The SATA III interface caps sequential throughput at 6 Gb/s, which bounds the drive at up to 560 MBps read and 530 MBps write. Random read reaches up to 11,000 IOPS at QD1 and 100,000 IOPS at QD32, while random write reaches up to 43,000 IOPS at QD1 and 90,000 IOPS at QD32. These figures represent the practical ceiling of the SATA bus for this class of drive.

256GB capacity and headroom

The 256GB capacity suits operating systems, applications and active project files with room for over-provisioning managed by the auto garbage collection algorithm. Average active power draw is 2.0W with a 3.3W burst maximum, and the drive operates from 0°C to 70°C. MTBF is rated at 1,500,000 hours, indicating long-term reliability for sustained workloads.

Questions about this item

Will this 2.5-inch drive fit my laptop’s 7 mm bay?

The drive is 7.00 mm high, matching the standard slim 2.5-inch bay used in most modern laptops

Does the box include a SATA cable or mounting bracket for a desktop install?

The package contains only the SSD and a user manual; cables, screws and brackets are not included

Can I use the hardware AES 256-bit encryption with Windows BitLocker?

Yes, the drive supports TCG Opal and IEEE 1667, so BitLocker can offload encryption to the controller
