Data Caching
A solid-state drive (SSD) is a media which uses flash modules to save info. The solid-state drives are still fairly new and more pricey when compared to classic hard disk drives (HDD), but they are faster, so they are frequently employed for Operating Systems and apps on both PCs and web hosting servers. An SSD is recommended as it doesn't have spinning disks that restrict its speed and may even cause overheating like it may happen with an HDD. A large number of companies use SSDs for caching purposes, so all of the site content which is accessed more often will be held on this type of drives, while all the other content will be located on standard HDDs. The main reason to use this type of a configuration is to balance the price and overall performance of their hosting platform and to minimize the load on the HDDs resulting from countless reading and writing processes.
