The thing is, hard drive space has NOT increased. HDDs reached 2TB and basically stopped. SSDs reach 4TB now and there's not much larger. And not much matters in that regard anyway because only specialist boards support more than one or two m.2 connections.
What? You can buy brand new 24 TB HDDs right now. They make 8 TB external SSDs.

Those drives are just racks/arrays of ~2TB storage. The 24 TB HDD has 10 2TB platters in it.
