Ask HN: Methods and Materials for Organizing My (Old) Digital Life

I've got a lot of digital stuff. Photos/videos/etc.

I'm currently trying to work on my network administration skills at my full-time job.

Looking to purchase a Synology NAS or something similar to start creating a repository for all of my personal projects/data.

Thoughts on where to start? Considerations for organizing files and documenting what I have?

Curious to see how others have handled archiving years of data. Thanks HN!
