A solid-state drive (SSD) enhances the performance of each app running on it compared with a classic hard-disk drive (HDD). The reason is that an SSD uses multiple interconnected flash memory units, so there are no physical parts to move. In contrast, a hard-disk drive employs spinning disks and any reading or writing process causes the disks to rotate, which means that the speed of an HDD is restricted. As the cost of the two kinds of drives are different as well, many PCs and web servers are equipped with an SSD for the operating system and various applications, and an HDD for file storage, in this way balancing price and overall performance. A web hosting service provider could also use a solid-state drive for caching purposes, so files which are accessed very often will be saved on such a drive for accomplishing higher loading speeds and for reducing the reading/writing processes on the hard drives.
SSD with Data Caching in Shared Web Hosting
If you host your websites in a shared web hosting account with our company, you'll definitely notice their exceptional performance. The reason is that our cloud platform uses only SSD drives for all files, emails and databases and we don't use HDDs for any part of the web hosting service. In addition to the innovative ZFS file system, this setup will raise the speed of your websites tremendously. For load-balancing, we also use multiple SSDs for caching purposes only. Any content which generates more traffic or causes lots of reading/writing processes is duplicated on them instantly, so the load on the main drives will be lower, 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 lessens the chance of a disk failure, which is one more guarantee for the reliability of all content that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we provide are generated on a cloud platform which uses only SSD drives. We do not use HDDs anymore, so your Internet sites will load very fast because we employ SSDs for every aspect of the service - files, databases and emails. As some customers may host sites that are more frequently visited than others, we also use multiple drives for caching. Our system discovers all of the content which is loaded more often and clones 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 influence the performance of the rest of the Internet sites that are stored on the same primary drive. Using caching drives also raises the life-span of the main storage SSDs and lowers the possibility of disk failures.
