There is also a ‘head’ that moves across the spinning disk to read the data (like an old record player). Traditional hard drives have a spinning disk inside. Otherwise you can have a go at installing one yourself. If you have an older one that you’d like to upgrade you should be able to take your Macintosh computer to a local dealer and have them install an SSD drive. All MacBooks now come standard with an SSD drive. I can’t think of any reason why you should not be using one.

Now SSD drives have dropped dramatically in price and you can just replace your existing drive with an SSD one. Back then SSD drives were expensive and the whole process I described was a bit complicated.

In 2015 I wrote this post about installing an SSD drive.
