A solid-state drive is much quicker than any regular hard-disk drive. It is because an HDD employs rotating disks, which can rotate only so fast and the more data is read and written, the slower and hotter they get, at the same time an SDD works with modules of flash memory, so there are no physically moving components. The access speeds for an SSD are significantly higher, which makes this sort of drives a recommended solution every time speed is needed. Because of this SSDs are frequently used for the Operating System on a personal computer and for keeping data that's accessed repeatedly on web servers. Many service providers also use a combination of both drives, so they keep the data on hard drives, but they use a couple of solid-state drives to cache the more frequently used data and due to this fact, the data loads faster while the load on the HDDs is lowered because their disks need to spin less frequently in order to read and write.
SSD with Data Caching in Website Hosting
If you host your sites in a website hosting account from our company, you will notice their excellent performance. This is because our cloud platform uses only SSD drives for all of the files, e-mails and databases and we don't use HDDs for any part of the website hosting service. Together with the revolutionary ZFS file system, this setup will raise the speed of your sites significantly. For load-balancing, we also use numerous SSDs for caching purposes only. Any content which generates more traffic or creates a lot of reading/writing processes is duplicated on them instantly, so the load on the primary drives will be reduced, thus the overall performance of all sites hosted on our end will be better. This in turn prolongs the life of the main drives and decreases the chance of a disk failure, which is another warranty for the integrity of any content which you upload to your account.
