A solid-state drive (SSD) improves the performance of every app running on it in comparison to a classic hard-disk drive (HDD). The reason is that a solid-state drive works by using multiple interconnected flash memory units, so there are no physical parts to move. In comparison, an HDD features spinning disks and every reading or writing process causes the disks to move, which means that the speed of an HDD is restricted. Because the cost of the two kinds of drives also differ, a lot of personal computers and web servers are provided with an SSD for the OS and random applications, and an HDD for file storage, in this way balancing cost and effectiveness. A hosting provider can also use an SSD for caching purposes, which means that files which are accessed regularly will be stored on such a drive for reaching higher loading speeds and for minimizing the reading/writing processes on the hard disks.
SSD with Data Caching in Shared Hosting
If you host your Internet sites in a shared hosting account from our company, you'll notice their fantastic performance. The reason is that our cloud platform uses only SSD drives for all of the files, email addresses and databases and we do not use HDDs for any part of the web hosting service. In addition to the innovative ZFS file system, this configuration will increase the speed of your Internet sites tremendously. For load-balancing, we also use a number of SSDs for caching purposes only. All the content which generates more traffic or creates plenty of reading/writing processes is duplicated on them promptly, so the load on the main drives will be reduced, thus the overall performance of all sites hosted with us will improve. The latter subsequently prolongs the life of the primary drives and decreases the potential for a disk failure, that is an additional guarantee for the reliability of all content that you upload to your account.
