A solid-state drive (SSD) boosts the performance of any application running on it compared to 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're no physical parts to move. In comparison, a hard disk employs spinning disks and any 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 kinds of drives also differ, lots of personal computers and web servers are set up with an SSD for the operating system and various applications, and a hard-disk drive for file storage, thus balancing price and efficiency. A hosting provider could also use an SSD for caching purposes, thus files which are used frequently will be located on this type of a drive for achieving improved loading speeds and for minimizing the reading/writing processes on the hard drives.
SSD with Data Caching in Semi-dedicated Servers
If you get one of our semi-dedicated server plans, your websites will be stored on a cloud platform that uses exclusively SSD drives for the storing of files, databases and emails. Along with the advanced ZFS file system that we use, this configuration guarantees extremely fast loading speed for every web app hosted on our end. To guarantee that the websites of one customer won't affect the ones of another, we also use numerous SSDs as cache - our system finds files that are accessed more frequently and copies them, so that they start loading from the caching drives. The content on the latter is updated dynamically and because of this we can balance the load on all the drives, ensure their extended life-span, decrease the risk of disk failures and, of course, supply a super fast and reliable Internet hosting service.
