A solid-state drive (SSD) improves the performance of any application running on it in comparison with a classic hard-disk drive (HDD). The reason is that a solid-state drive functions with many different interconnected flash memory modules, so there're no physical parts to move. In contrast, an HDD contains spinning disks and each reading or writing process causes the disks to rotate, meaning the speed of an HDD is fixed. As the prices of the two types of drives also differ, many personal computers and web servers are provided with an SSD for the OS and random applications, and a hard disk for file storage, thus balancing cost and performance. A hosting service provider may also use a solid-state drive for caching purposes, thus files that are used frequently will be located on this type of a drive for reaching better loading speeds and for reducing the reading/writing processes on the hard-disk drives.
SSD with Data Caching in Web Hosting
If you host your Internet sites in a web hosting account with our company, you'll definitely notice their excellent performance. This is because our cloud platform uses exclusively SSD drives for all of the files, emails and databases and we do not use HDDs for any part of the Internet hosting service. Together with the amazing ZFS file system, this setup will raise the speed of your websites substantially. For load-balancing, we also use multiple SSDs for caching purposes only. All of the content that generates more traffic or creates plenty of reading/writing processes is copied on them instantly, so that the load on the main drives will be reduced, thus the overall performance of all sites hosted with us will be better. The abovementioned in turn prolongs the life of the main drives and reduces the chance of a disk failure, which is an additional guarantee for the reliability of any content that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we provide are made on a cloud platform that uses exclusively SSD drives. We don't use HDDs any longer, so your Internet sites will load amazingly quickly since we employ SSDs for every aspect of the service - files, databases and emails. Considering that some customers may host Internet sites that could be more frequently visited than others, we also use multiple drives for caching. Our system identifies any content which is accessed more regularly and duplicates it on these drives in order to load it from them. This setup is used for load-balancing purposes as we make sure that several reading/writing intensive sites will not affect the performance of the rest of the sites which are stored on the same primary drive. Using caching drives also increases the lifespan of the main storage SSDs and reduces the potential for disk failures.
