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

This approach allows for more stable and predictable performance, as well as more efficient caching and power management across different scenarios—from gaming to video streaming. The maximum read speed reaches 7300 MB/s, and write speed—up to 6300 MB/s, making the drive confidently rank 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 in writing and up to 800 thousand IOPS in reading, rendering the device effective for multitasking and heavy load on the file system.

Despite the use of 3D QLC NAND, the WD Black SN850X demonstrates an impressive endurance rating—600 TBW, and reliability compliant with the standard: 1.77 million hours MTBF. Additional stability under high loads is provided by the DRAM buffer, enhancing the efficiency of handling large amounts of data and minimizing delays in complex scenarios. Besides all stated, the manufacturer emphasizes the use of a thin graphene heatsink and an official 5-year warranty.
