Late 2011 MacBook Pro Problem

For those simply here looking for solutions: I installed the OS onto a 128 gb stick and it runs flawlessly now.

Even though I got it working, it got me curious. How come any os (From something as demaning as High Sierra or Deepin Linux, to ChromeOS, all of which I have tried) works completely fine on a spinning hard drive for a day or two then drastically slows down? Mainly just curious. Sometimes would happen to other Live USBs.

I've gotten into computers a lot as I found this old MacBook Pro in an old box in the basement, which barely worked. After improperly erasing the hard drive and going through pain trying to reinstall Lion back on, I finally did it. Like 5 times, and fixed the Superdrive. This got me curious as though spinning hard drives are inferior, they shouldn't be this inferior, especially having not really been used.

HDD aren't necessarily inferior, they just have different operational envelopes ... they do things differently from an SSD. HDDs are mechanical and are subject to all sorts of things that might affect mechanical devices. That can be electronics wearing out to simply an overfilled disk. Remember, an HDD must actually physically seek data and that takes time; the more data you have the longer. And over time mechanical parts do wear.

It's interesting to note that when SSDs first came out they were believed to be inferior to HDDs. Technology changes, HDDs are mature tech and SSDs are just now moving into their own.

There are applications that on a cost of storage basis ... $ per MB, HDDs are a better choice. Speed is not always the defining factor

Old hard drives sometimes have problems with the lubricants gumming up ("stiction").
