A solid-state drive (SSD) enhances the performance of every application running on it when compared with a classic hard-disk drive (HDD). The reason is that a solid-state drive functions with multiple interconnected flash memory units, so there are no physical parts to move. In contrast, an HDD functions with spinning disks and any reading or writing process causes the disks to spin, so the speed of an HDD is limited. Because the prices of the two types of drives also differ, a large number of computer systems and web servers are equipped with an SSD for the operating system and random applications, and a hard-disk drive for file storage, thus balancing cost and efficiency. An Internet hosting provider can also use an SSD for caching purposes, thus files which are used repeatedly will be saved on this type of a drive for reaching higher loading speeds and for reducing the reading/writing processes on the HDDs.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we provide are generated on a cloud platform that employs only SSD drives. We don't use HDDs any longer, so your websites will load quickly as we employ SSDs for each part of the service - files, databases and emails. Considering that some users may host websites which are more popular than others, we also use a number of drives for caching. Our system discovers all the content which is accessed more frequently and duplicates it on these drives so as to load it from them. This setup is used for load-balancing purposes as we guarantee that several reading/writing intensive Internet sites will not affect the performance of the rest of the Internet sites which are stored on the very same primary drive. Using caching drives also raises the life-span of the main storage SSDs and decreases the chance of disk failures.
