Replacing a hard drive with an SSD is one of the best things you can do to dramatically improve the performance of your older computer. Without any moving parts, SSDs operate more quietly, more efficiently, and with fewer parts to break than hard drives that have spinning platters
An SSD is the single biggest upgrade you can give your computer, and prices have come down dramatically. Solid-state drives are so much faster because they don’t have a spinning magnetic platter and moving head. After upgrading, you’ll be amazed at the performance improvements and wondering why you waited so long.
