Key Features & Technologies

• Elite Gaming Performance: Blistering 7,300 MB/s read speeds drastically reduce load times and help eliminate throttling, lagging, and texture pop-ins in modern games.
• Game Mode 2.0: Exclusive to the SN850X, this feature (enabled via the WD_BLACK Dashboard on Windows) optimizes system resources and drive performance specifically for gaming workloads.
• DirectStorage™ Supported: Leverages Microsoft’s DirectStorage technology to bypass the CPU and load game assets directly from the SSD to the GPU, resulting in near-instantaneous load times in supported titles.
• Advanced Thermal Management: Features Predictive Loading, Overhead Balancing, and Adaptive Thermal Management to maintain consistent peak performance during intense, sustained workloads.
• WD_BLACK Dashboard: Free downloadable software (Windows only) to monitor drive health, check capacity, customize RGB lighting (on heatsink models), and apply firmware updates.
