A solid-state drive is substantially quicker than any standard hard-disk drive. It is because an HDD works by using spinning disks, that can rotate only so fast and the more data is read and written, the slower and hotter they become, while an SDD works with modules of flash memory, therefore there are no physically moving parts. The access speeds for an SSD are much higher, which makes this type of drives a recommended solution every time speed is needed. Because of this SSDs are in many cases used for the Operating System on a laptop or computer and for saving data that's used frequently on servers. A large number of service providers also use a combination of the two drives, so they keep the data on hard-disks, but they use several solid-state drives to cache the more often used data and because of that, the data loads a lot quicker while the load on the HDDs is lowered because their disks need to spin less often in order to read and write.
SSD with Data Caching in Shared Hosting
In case you host your websites in a shared hosting account from us, you'll definitely notice their excellent performance. The reason is that our cloud platform uses exclusively SSD drives for all of the files, e-mails and databases and we don't use HDDs for any part of the hosting service. Together with the amazing ZFS file system, this setup will boost the speed of your sites tremendously. For load-balancing, we also use a number of SSDs for caching purposes only. All content that generates more traffic or causes lots of reading/writing processes is copied on them automatically, 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 lessens the chance of a disk failure, that is an additional warranty for the integrity of any content that you upload to your account.
