Top solution in the Western Digital lineup of drives, designed for gamers, creators, and enthusiasts who value not just high speed, but a precise combination of architecture, reliability, and thoughtful cooling. This is the flagship of 2022, built on the proprietary SanDisk hardware platform, displaying outstanding performance in the PCI-E 4.0 class. The core of the device is the SanDisk 20-82-20035-B2 controller—an exclusive Western Digital development, optimized for its own firmware and architecture.

This approach ensures more stable and predictable performance, along with more efficient caching and power management in different scenarios—from gaming to streaming video processing. The maximum read speed reaches 7300 MB/s, write speed—up to 6300 MB/s, making the drive confidently among the fastest models among consumer Gen4 solutions. High performance is supported not only in linear operations but also in random access: up to 1.1 million IOPS for writing and up to 800 thousand IOPS for reading, making the device effective in multitasking and intensive file system load.

Despite using 3D QLC NAND, the WD Black SN850X demonstrates an impressive endurance of 600 TBW, as well as reliability meeting the standard: 1.77 million hours mean time to failure. Additional stability under high loads is provided by the DRAM buffer, enhancing the efficiency of working with large data volumes and minimizing delays in complex scenarios. Besides all that, the manufacturer emphasizes the use of a thin graphene heatsink and official 5-year warranty.
