A solid-state drive (SSD) boosts the performance of each application running on it compared with a common hard-disk drive (HDD). The reason is that a solid-state drive uses many different interconnected flash memory modules, so there are no physical parts to move. In comparison, a hard disk employs spinning disks and each reading or writing process causes the disks to move, meaning the speed of an HDD is fixed. As the prices of the two types of drives are also different, many computer systems and web servers are equipped with an SSD for the operating system and various applications, and a hard disk for file storage, thus balancing cost and efficiency. A web hosting service provider could also use a solid-state drive for caching purposes, thus files that are accessed repeatedly will be held on this type of a drive for accomplishing improved loading speeds and for reducing the reading/writing processes on the hard-disk drives.
SSD with Data Caching in Cloud Hosting
The cloud platform where we create cloud hosting accounts uses only 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 regardless of whether you open a page or check for new emails through webmail, the content will load right away. So as to offer even better speeds, we also use a number of dedicated SSDs that work only as cache. All content that generates lots of traffic is copied on them automatically and is later read from them and not from the main storage drives. Of course, that content is replaced dynamically for better performance. What we achieve that way apart from the improved speed is lowered overall load, thus lower potential for hardware failures, and longer lifespan of the main drives, that is one more level of security for any info that you upload to your account.
