A solid-state drive is significantly faster than any conventional hard-disk drive. This is because a hard-disk drive uses spinning disks, which can rotate only so fast and the more data is read and written, the slower and hotter they become, at the same time an SDD works with modules of flash memory, so there aren't any physically moving parts. The access speeds for an SSD are a lot higher, which makes this kind of drives the best solution any time speed is needed. That's why SSDs are frequently used for the Operating System on a personal computer and for keeping data that is used regularly on servers. A lot of providers also use a combination of both drives, so they save the data on HDDs, but they use a couple of solid-state drives so as to cache the more frequently used data and because of this, the data loads much quicker while the load on the HDDs is lowered since their disks have to spin less often to read and write.

SSD with Data Caching in Shared Hosting

The cloud platform where we make shared hosting accounts uses exclusively SSD drives, so your web apps and static Internet sites will load extremely fast. The SSDs are used for files, emails and databases, so regardless if you open a page or check for new email messages with webmail, the content will load right away. So as to ensure even higher speeds, we also use multiple dedicated SSDs that function only as cache. All the content that generates a lot of traffic is copied on them automatically and is later on read from them and not from the main storage drives. Needless to say, that content is replaced dynamically for better efficiency. What we achieve this way except for the better speed is lowered overall load, thus reduced chance of hardware failures, and extended lifespan of the primary drives, that's one more level of security for any info that you upload to your account.
