The type of hard drive you choose will depend on your personal computer requirements and budget. The most economical hard drives today are hard disk drives, which store and retrieve information on hard, rotating disks. HDDs are also the largest capacity hard drives available, making them ideal for anyone who needs to store large amounts of data. If you plan on storing thousands of high-resolution digital photos or using your computer to store videos, an HDD is likely your best option. Solid-State Drives, on the other hand, are more expensive and have much lower storage capacities, but they are significantly faster. A computer booting from an SSD can typically boot in a matter of seconds. SSDs are also quiet and require less physical space. Most mobile devices and many laptop computers utilize SSD storage to reduce their weight and increase performance.
