Then I downloaded a couple from Win-Raid where Fernando posted different SATA drivers and tests: I've tested this and happens without a shadow of a doubt. These 2 drivers make the boot slower, even on an SSD.

If I use the ones Windows Update gives via device manager, I get some recent ones (right now, I have 2, one from 2019 and from 2020, called Intel R C220 series, this from hitting update device driver a couple of times). I've tried 5 SATA drivers and all of them are, well, different. This post may not be too relevant, but I like to get all of the performance I can from my PC and well, if I can also optimize the I/O, even better.
