A solid-state drive is noticeably quicker than any standard hard-disk drive. The reason is that a hard-disk drive uses rotating disks, that can rotate only so fast and the more data is read and written, the slower and warmer they get, while an SDD employs modules of flash memory, hence there are no actually moving parts. The access speeds for an SSD are a lot higher, which makes this sort of drives the right solution in case speed is needed. That's why SSDs are frequently employed for the Operating System on a PC and for saving data which is used regularly on web servers. Many service providers also use a combination of both drives, so they store the data on hard-disks, but they use several SSDs in order to cache the more often used data and as a result, the data loads faster while the load on the HDDs is decreased as their disks need to spin less frequently in order to read and write.

SSD with Data Caching in Web Hosting

The cloud platform where we create web hosting accounts uses solely SSD drives, so your web apps and static Internet sites will open very fast. The SSDs are used for files, e-mails and databases, so regardless of whether you open a page or check for new email messages using webmail, the content will load right away. So as to ensure even higher speeds, we also use a group of dedicated SSDs which function only as cache. Any content which generates a lot of traffic is copied on them automatically and is later read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for much better performance. What we achieve this way aside from the improved speed is decreased overall load, thus reduced probability of hardware failures, and extended lifespan of the primary drives, that's one more level of protection for any information that you upload to your account.
