Hard drives are delicate machines and must be treated with care. They are not designed to be the one and only storage for all your work, photos and videos. Imagine your computer never booting up again, and then imagine it happening during the most important job you have ever done. That’s how bad it could be, and often is for a lot of people.
A good lifespan for a hard drive is now probably around 3-5 years. In reality we often see hard drives that are only a few months old. If you’re a gambler then maybe you have got away with it so far, but is it really worth the risk?
