It‘s not only related to HDDs but to all electronic components. The shortage of various small components and parts affects every industry. Classic hardware, network equipment, displays, cameras, drives, servos, … - guess where you can find electronic components today.
Simple example: standard Dell 24“ display. Bought 12 of them in 09/2020 for 119€ each. Price today: 290€.
Standard industry drive: price in 11/2020: 750€. Today: 1,600€.
And beside the price spiral delivery times (especially in the industrial sector) have gone sky-high ☹️
