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 PCIe 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.

A good SSD that is on par with the KC3000, but runs hotter. It's almost the same drive, but with some minor drawbacks in terms of temperature. The drive itself is quite high-quality and maintains normal temperatures under the motherboard's secondary heat sink. Cache, quality, similarity to KC3000 Temperature in some scenarios  Sriblo: use WD WDS100T2X0E more than year |
Corresponds to the declared speeds Not a bad price/performance ratio I still peeled off the sticker, under the native x570 radiator, after running CrystalDiskMark, it was 5 degrees lower at the peak Dmitriy Mitus: use WD WDS200T2X0E less than month |
