Is it worth swapping my laptop hard drive for an SSD?

Neal has a six-year-old old Dell Studio 17 laptop and wonders if the hard drive is likely to fail. Is this a good time to swap it for a faster SSD, or buy a new PC?

My main computer is a Dell Studio 17 laptop from 2010 (specification attached). In my home office, I hook it up to a separate keyboard, mouse and monitor.

As a part-time university lecturer, I run the usual software - Microsoft Office, Adobe Illustrator etc - plus some specialist software such as ArcMap, part of the ArcGIS suite.

The Dell Studio 17 was a solid desktop replacement laptop with plenty of power but not much portability. It's already running Microsoft Windows 10 with 8GB of memory, so there's no urgent need to upgrade or replace it.
