Solid-state drives (SSDs) are currently the fastest form of storage available, and can give your system a massive boost in application and OS load times, data-transfer speeds and overall system responsiveness. Their lightning speed comes from using flash memory chips, which unlike traditional hard drives have no moving parts. This makes them more reliable, smaller, lighter and less power hungry, but they can cost significantly more and oftentimes have less capacity. Scan recommends that anyone in the market for a performance PC opts for an SSD.
