A solid-state drive is considerably faster than any standard hard disk. It is because a hard-disk drive employs rotating disks, that can rotate only so fast and the more info is read and written, the slower and warmer they get, while an SDD operates with modules of flash memory, therefore there aren't any physically moving parts. The access speeds for an SSD are substantially higher, which makes this kind of drives the right solution any time speed is needed. This is the reason why SSDs are in many cases used for the Operating System on a computer system and for saving data that's accessed often on servers. Many providers also use a combination of the two drives, so they store the data on hard drives, but they use several solid-state drives to cache the more frequently used data and because of that, the data loads a lot quicker while the load on the HDDs is decreased since their disks have to spin less often to read and write.
SSD with Data Caching in Shared Web Hosting
The cloud platform where we make shared web hosting accounts uses solely SSD drives, so your web apps and static sites will load very quickly. The SSDs are used for files, email addresses and databases, so regardless if you open a page or check for new e-mail messages with webmail, the content will load quickly. To offer even higher speeds, we also use numerous dedicated SSDs which function only as cache. All content that generates lots of traffic is copied on them automatically and is later on read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for better performance. What we achieve by doing this in addition to the improved speed is reduced overall load, thus lower potential for hardware failures, and extended lifespan of the main drives, which is one more level of protection for any info that you upload to your account.
