@sjmulder Yep, planned obsolescence at work. There are many factors going into this, some are software industry and some are the the nature of hardware. Contingencies for memory access escalation, such as Row-hammer and it's ilk, mean the microcode and/or have have changed such that throughput is reduced. Your disk(s) (platter or solid state) both will degrade in speed for different reasons. A new driver might introduce some chaos into how your OS kernel behaves.
