Sudden general slowness on a 2011 13” unibody. Boot is slow, random hangs. Processes are quite slow as well. Endless circling while trying to load youtube etc. Activity monitor suggests CPU usage is down, lots of free RAM. Fresh resin tall of OS (took forever) - still same issues.
Likely HDD cable? Any other suggestions?
Is this a good question?

It’s almost always that cable. If you’ve never changed it, replace it and test - 99% chance it solves the issue.
Refer to this question for information on how to deal with it and which cable you need: Will Crucial MX500 2TB 3D CT2000MX500SSD1 SSD work in my Mid-2012 MBP?
While you’re there, you might as well clean the dust out and repaste it if you feel comfortable doing so and have thermal paste available - it’s one of those jobs that takes a while, so you might as well do it now. You can deal with the dust by removing the fans if you don’t have thermal paste or aren’t comfortable doing it.
