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 |
