The SSD to trust
Get industry-leading reliability with the 860 PRO. Powered by the latest V-NAND technology and a robust algorithm-based controller, it readily handles heavy workloads of high-end PCs, workstations and NAS (Network Attached Systems) to give lasting assurance to gamers, IT and creative professionals.
Enhanced performance
Speeds are more consistent and sustained, even with heavy workloads and multiple tasks. The 860 PRO performs at sequential write speeds up to 530 MB/s with the best combination of the latest V-NAND and a refined controller, delivering sequential read speeds up to 560 MB/s.
Fierce endurance
Under heavy workloads, endurance is everything. Safely store and render 4K videos and 3D data used by the latest applications, up to 8x higher TBW* than the previous 850 PRO. The latest V-NAND technology gives you industry-leading endurance backed by a 5-year or up to 4,800 TBW limited warranty.
Smart compatibility
Benefit from faster, more fluid communication with your host system. The refined ECC algorithm and a new MJX controller generate higher speeds, and the improved queued trim enhances Linux compatibility. Our advanced engineering makes the 860 PRO more compatible with your computing system.
