I have no idea why companies would not activate it by default but unfortunately it clear companies that did not choose despite the native chipsets.

If you already have Windows installation with ATA it a bit difficult to switch to AHCI because the system does not have the correct driver installed leading to the blue screen of death. You can install it even if you are only in AHCI but if you do not install the RST package after you install Windows you will not get maximum performance from the drive. SSD types are slightly less reliable than SSDs with foreground GC due to more window features SSD is prone to corruption if power was lost at the moment. The 4k-64 is a random reader with a very high amount of meat that you would not see under normal workload. Because SSD can handle IO requests so fast compared to HDD the average workload will ely exceed 1.
