A solid-state drive (SSD) boosts the performance of each application running on it in comparison to a regular hard-disk drive (HDD). The reason is that an SSD uses a variety of interconnected flash memory modules, so there're no physical parts to move. In comparison, a hard-disk drive contains spinning disks and any reading or writing process causes the disks to spin, meaning the speed of an HDD is fixed. Since the cost of the two kinds of drives are different as well, lots of personal computers and web servers are provided with an SSD for the OS and various applications, and a hard disk for data storage, this way balancing cost and efficiency. A web hosting service provider may also use an SSD for caching purposes, so files that are used on a regular basis will be located on this type of a drive for achieving improved loading speeds and for reducing the reading/writing processes on the hard drives.
SSD with Data Caching in Semi-dedicated Servers
If you register for one of our semi-dedicated server solutions, we'll hold your content on SSD drives and this is valid not only for the files, but also for all databases and e-mail messages. That way, your script-driven applications and webmail will load amazingly quickly. We use dedicated SSDs for caching too. Traffic-intensive website content is duplicated automatically on these drives, so we ensure that several heavy websites which generate a lot of reading and writing processes shall not affect the other websites that share the same drive. By reduction of the overall system load we also increase the lifespan of the primary storage drives and decrease the chance of a disk failure, so by using SSD drives for caching purposes, we add another level of stability for your site content.
