Solid State Drive: What’s the Diff? or our two-part series, HDD vs SSD: What Does the Future for Storage Hold? Why Upgrade to an SSD? Compared to HDDs, SSDs are more shock resistant and are not affected by magnetic fields.įor more about the difference between hard disk drives and SSDs, check out Hard Disk Drive vs. That’s different than the regular RAM in your computer, which is reset when you turn off or restart the computer. In other words, the information stays put on memory chips once it’s been written. Spinning hard drives are also more delicate and prone to failure if they’re dropped too hard.īy comparison, SSDs contain a form of non-volatile computer memory. Hard drives can also be noisy and use a fair amount of power - reasons to consider switching to an SSD especially if you’re a laptop user. They’re built to last, but they do eventually wear down and wear out.
Those disks spin at high rates of speed (thousands of revolutions per minute), so there are a lot of moving parts inside a hard disk drive. The read/write head on that arm magnetically reads and writes binary data concentrically on the disk. A part called the actuator moves a tiny arm that floats a miniscule distance above the surface of the disk platters. Conceptually, hard drives work a bit like old-fashioned record players. Historically, most computers have used spinning hard disk drives for permanent data storage.
That said, there are some practical challenges you’ll need to consider before you do, so let’s look further into SSD drives.

It will completely change your computing experience. Is your computer performing slower than you like, or are you looking for a way to boost performance? If your computer is more than a couple of years old, replacing the hard drive with an solid-state drive (SSD) is one of the most cost-effective changes you can make. SSDs are changing rapidly, however, so we updated this post by Peter Cohen from December of 2016 with the latest information to help you take advantage of SSDs. Adding or upgrading an SSD is, along with adding memory, the most popular DIY computer upgrade.
