An SSD (solid state drive) is a hard drive that uses flash memory instead of the magnetic platters used in traditional hard drives. This has the advantages of being a lot faster and more reliable, albeit at a higher cost per GB.
Upgrading to an SSD is the easiest and most economical way to breathe new life into an aging PC. Today, most PC performance woes are the result of slow read and write speeds on behalf of the main storage device, not a lack of CPU performance. Upgrading to a SSD can breathe new life into your old PC by enhancing boot-up speed, application loading, and multi-tasking performance.
