Gallon Ziplocs with folded over cardstock sheets for labels, also keeps them rigid so bags of cables that aren’t full don’t get buried. I have two bins, one with common stuff in my office and the other stays in the basement with all the weird cables.
I have like 4 drawers of cables and connectors that go back at least 2 decades of various standards and ports and configurations. So you’d think that any time I need to find a cable, it should be no big deal, right? NOPE. Can’t find it, and end up having to order a new one. Sometimes I wonder why I even bother keeping any around.
You gotta do it man, once you’ve done it it’s super easy to maintain and you can always find that cable you need. This is literally the only thing in my house that indicates a civilized person lives here, so if you organize nothing else do this.
Actually the girlfriend organized most of the cables in those drawers a few years ago but it made looking got things worse.
