4TB SATA SSD for workstations and NAS

The Samsung 860 Pro MZ-76P4T0E is a 2.5-inch internal solid state drive built for high-end client PCs, workstations and network attached storage. It uses V-NAND 2-bit MLC flash and a Samsung MJX controller to deliver consistent throughput for demanding workloads.

4TB capacity with 4GB LPDDR4 cache

Sequential reads reach 560 MBps and writes reach 530 MBps. Random 4KB reads hit 100,000 IOPS at queue depth 32 and 11,000 IOPS at queue depth 1; random writes hit 90,000 IOPS at queue depth 32 and 43,000 IOPS at queue depth 1. MTBF is rated at 1,500,000 hours. Active power averages 2.2W with a 4.5W maximum; idle power is 0.5W and device sleep is 7 mW.

2.5-inch SATA III drive with AES-256 encryption

The drive fits standard 2.5-inch bays and connects through a SATA III interface. AES-256-bit hardware encryption protects data without software overhead. Samsung Magician software provides drive management and monitoring. Operating temperature range is 0°C to 70°C.

FeaturesSamsung V-NAND Technology
Samsung's V-NAND flash memory helps to overcome the limitations of conventional planar NAND architecture. It stacks 64 cell layers vertically over one another rather than trying to fit itself onto a fixed horizontal space, in order to provide high density and performance with a small footprint.
Fast Read/Write Performance
The 860 PRO performs at sequential write speeds up to 530 MB/s and sequential read speeds up to 560 MB/s with a robust a robust algorithm-based Samsung MJX controller (up to 1 GHz).

Questions about this item

Will the 2.5 inch SATA III 860 Pro work in a laptop that only has an older SATA II port?

Yes, the SATA III interface is backward compatible with SATA II ports, though sequential speeds will be limited to the older port's maximum throughput.

How can I verify the 860 Pro is delivering its rated 560 MBps read and 530 MBps write performance after installation?

Run a benchmark tool like CrystalDiskMark using a 1 GB test file at queue depth 32; results should approach the stated sequential and random IOPS figures.

Does the MZ-76P4T0E retail box include a 2.5 to 3.5 inch mounting bracket or cloning software for my existing drive?

The package contains only the 4TB 2.5 inch drive; mounting brackets, SATA cables and migration software are sold separately.
