A solid-state drive is much faster than any regular hard-disk drive. It is because an HDD employs rotating disks, that can rotate only so fast and the more info is read and written, the slower and warmer they become, whereas an SDD employs modules of flash memory, so there are no physically moving components. The access speeds for an SSD are considerably higher, which makes these drives the best solution if speed is needed. This is the reason why SSDs are in many cases used for the Operating System on a PC and for keeping data which is accessed regularly on servers. A large number of providers also use a combination of the two drives, so they save the data on HDDs, but they use a couple of solid-state drives in order to cache the more frequently used data and for that reason, the data loads faster while the load on the HDDs is reduced as their disks have to spin less often in order to read and write.
SSD with Data Caching in Shared Hosting
The cloud platform where we create shared hosting
accounts uses solely SSD drives, so your web apps and static sites will load very fast. The SSDs are used for files, e-mails and databases, so regardless of whether you load a page or check for new e-mail messages through webmail, the content will load instantly. To offer even higher speeds, we also use a group of dedicated SSDs which function only as cache. All content that generates lots 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 better efficiency. What we achieve that way in addition to the improved speed is decreased overall load, thus decreased probability of hardware failures, and longer lifespan of the primary drives, which is one more level of security for any data that you upload to your account.
