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
Sriblouse WD WDS100T2X0E more than year
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
