Model overview based on user reviews  
WD Black SN850X is a high-performance PCIe 4.0 NVMe SSD aimed at gaming PCs and PS5 systems. It delivers strong sequential and random performance, improved write behavior over the previous SN850, and offers capacities up to 8 TB. Sustained workloads can produce high temperatures, especially without a heatsink, while Game Mode 2.0 currently provides limited and workload-dependent benefits.

High-quality SSD with low temperatures
2 December 2025 
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

wonderful model, really honored
23 August 2024 
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
