Capacity and purpose
The Samsung 860 PRO MZ-76P256E is a 256GB 2.5" internal SSD built for high-end PCs, workstations and NAS units. It uses V-NAND 2-bit MLC memory and a Samsung MJX controller to deliver sustained performance for heavy workloads such as 4K video storage and 3D data rendering.
SATA III limits
The drive connects through a SATA III interface with a 600 MBps bus ceiling, so sequential reads top out at 560 MBps and writes at 530 MBps. Random 4KB performance reaches 100,000 IOPS read and 90,000 IOPS write at QD32, while QD1 figures sit at 11,000 IOPS read and 43,000 IOPS write.
Endurance rating
A 1,500,000-hour MTBF and V-NAND 64-layer construction give the drive the endurance needed for continuous high-intensity use. AES-256 hardware encryption and Samsung Magician software support are included for data security and management.

| Features | Samsung 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.

Kérdések a termékről
Should I choose the 256 GB capacity or a larger 860 PRO model?
The 256 GB version provides up to 560 MB/s sequential read and 530 MB/s write with a 512 MB LPDDR4 cache, while higher capacities in the same series can reach up to 90,000 random write IOPS at QD32 compared to 43,000 IOPS here.
What do the 560 MB/s read and 530 MB/s write speeds mean once the drive is installed in my PC?
Those are maximum sequential rates over the SATA 600 interface; real-world throughput will be slightly lower due to protocol overhead and system configuration, but large file transfers will still approach the SATA link limit.
Is the SATA III interface fast enough for this drive, or does it cap performance?
SATA III tops out at 600 MB/s, so the drive's 560 MB/s read and 530 MB/s write speeds run near the interface ceiling; the bottleneck is the SATA link itself, not the controller or V-NAND.
