However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
    • Maximum Read Speed: 7100 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)
