Thank you both very much, makes me feel better about finally clearing out the old tech I've been moving around with me for far too long (though the desktop I built as a high school kid is going to be hard to toss out...). I do have one of those cables but unpowered for SSDs, actually was recommended here a few years ago when an ex fried her PC and wanted to try to recover 100s of pictures and some recipe files (and it did that job, I earned a lot of bonus points the day that worked).
Thankfully there are nothing on the drives that I would want to keep, maybe some old stuff from my desktop since it was from High School through college, but I started backing up important files to external drives about 10 years ago.
