A solid-state drive (SSD) improves the performance of every app running on it compared with a common hard-disk drive (HDD). The reason is that a solid-state drive works by using many different interconnected flash memory units, so there are no physical parts to move. In contrast, a hard disk uses spinning disks and each reading or writing process causes the disks to rotate, which means that the speed of an HDD is fixed. As the prices of the two types of drives also differ, numerous PCs and web servers are provided with an SSD for the operating system and various applications, and a hard-disk drive for file storage, in this way balancing price and efficiency. A web hosting provider could also use a solid-state drive for caching purposes, which means that files which are used regularly will be stored on such a drive for achieving higher loading speeds and for reducing the reading/writing processes on the HDDs.
SSD with Data Caching in Hosting
The cloud platform where we make hosting accounts uses solely SSD drives, so your web applications and static sites will load extremely fast. The SSDs are used for files, emails and databases, so no matter if you load a page or check for new emails using webmail, the content will load very quickly. In order to ensure even better speeds, we also use multiple dedicated SSDs which work only as cache. All the content that generates a lot of traffic is copied on them automatically and is later read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for better performance. What we achieve by doing this in addition to the better speed is reduced overall load, thus decreased potential for hardware failures, and longer lifespan of the primary drives, which is one more level of security for any information that you upload to your account.
