A solid-state drive (SSD) improves the performance of each application running on it compared to an ordinary hard-disk drive (HDD). The reason is that a solid-state drive employs a number of interconnected flash memory units, so there're no physical parts to move. In contrast, a hard-disk drive works by using spinning disks and each reading or writing process causes the disks to move, meaning the speed of an HDD is restricted. As the cost of the two types of drives also differ, many desktops and web servers are equipped with an SSD for the OS and random applications, and a hard disk for data storage, in this way balancing cost and efficiency. A web hosting provider can also use a solid-state drive for caching purposes, so files which are used on a regular basis will be kept on this type of a drive for reaching improved loading speeds and for limiting the reading/writing processes on the hard drives.
SSD with Data Caching in Cloud Hosting
The cloud platform where we create cloud hosting accounts uses exclusively SSD drives, so your web apps and static Internet sites will open very fast. The SSDs are used for files, email addresses and databases, so no matter if you load a page or check for new emails using webmail, the content will load promptly. So as to offer even better speeds, we also use multiple dedicated SSDs that work only as cache. Any content which generates a lot of traffic is copied on them automatically and is later on read from them and not from the primary storage drives. Of course, that content is replaced dynamically for much better performance. What we achieve by doing this apart from the better speed is lowered overall load, thus lower probability of hardware failures, and extended lifespan of the main drives, that is one more level of protection for any data that you upload to your account.
