Modern operating systems on modern SSDs mostly just work. Plug a drive in, install the OS, and the defaults will get you a system that boots, runs games, and handles daily tasks without any manual intervention. Compared to a decade ago, we've come a very long way, but the defaults drives and motherboards ship with today are tuned for the widest possible range of hardware: laptops on battery, desktops with mixed SSD and HDD configurations, systems with limited RAM, and users who will never open a BIOS. For an enthusiast, some of these defaults are less than ideal, and they leave performance and potential endurance on the table.
