A solid-state drive (SSD) boosts the performance of every application running on it when compared to a classic hard-disk drive (HDD). The reason is that an SSD uses many different interconnected flash memory modules, so there're no physical parts to move. In comparison, a hard disk employs spinning disks and every reading or writing process causes the disks to spin, which means that the speed of an HDD is fixed. As the cost of the two types of drives are different as well, a large number of personal computers and web servers are equipped with an SSD for the OS and random applications, and a hard-disk drive for file storage, in this way balancing cost and overall performance. A website hosting service provider may also use an SSD for caching purposes, which means that files which are used very often will be held on this type of a drive for achieving better loading speeds and for minimizing the reading/writing processes on the HDDs.
SSD with Data Caching in Website Hosting
The cloud platform where we create website hosting accounts uses solely SSD drives, so your web applications and static sites will load very fast. The SSDs are used for files, e-mail addresses and databases, so regardless of whether you open a page or check for new e-mails with webmail, the content will load instantly. In order to ensure even better speeds, we also use a group of 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 improved performance. What we achieve by doing this aside from the improved speed is reduced overall load, thus reduced chance of hardware failures, and extended lifespan of the main drives, that's one more level of protection for any information that you upload to your account.
