I don't have any set pattern, but generally now solid state drives have got bigger/more affordable, I'm not just putting Windows on there. For example I bought a 1TB NVME drive, that runs Windows, apps and games that I'm newly installing.
On older systems, it's a bit different. For example I have a system with a 60GB SSD, what with windows update/driver bloat etc that's basically enough to run Windows, page file and basic apps, even then I have to do a clearup sometimes to remove temp files etc.
A slight aside but I've found that my 'data storage requirements growth' is a lot lower than it used to be. My main PC has two 1TB drives in, in fact useable space is only 1850GB. That's less than I had like 10 years ago. I think this is because internet connections are much faster and streaming services have taken off, so the need for local storage is reduced (don't need to keep games you aren't currently playing installed if you can download them in half an hour, don't need a big stash of video/music if you can stream it etc). I'm at the point now where I don't have mechanical drives in my main PC, speed is more important than storage capacity once you get to a certain size.
