A solid-state drive is significantly faster than any standard hard disk. It is because an HDD uses spinning disks, that can rotate only so fast and the more info is read and written, the slower and warmer they become, while an SDD takes advantage of modules of flash memory, hence there aren't any physically moving components. The access speeds for an SSD are much higher, which makes this sort of drives the best solution every time speed is needed. Because of this SSDs are often employed for the Operating System on a desktop or notebook and for saving data that's used often on hosting servers. A large number 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 to cache the more often used data and for that reason, the data loads quicker while the load on the HDDs is reduced as 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 solely SSD drives, so your web applications and static websites will open very quickly. The SSDs are used for files, email addresses and databases, so regardless of whether you load a page or check for new messages through webmail, the content will load quickly. To ensure even better speeds, we also use numerous dedicated SSDs that function only as cache. All content that generates a lot of traffic is copied on them automatically and is later read from them and not from the primary storage drives. Of course, that content is replaced dynamically for improved performance. What we achieve this way in addition to the improved speed is lowered overall load, thus lower chance of hardware failures, and prolonged lifespan of the primary drives, that's one more level of security for any information that you upload to your account.
