A solid-state drive is significantly faster than any standard hard disk. It is because an HDD uses spinning disks, which can rotate only so fast and the more information is read and written, the slower and warmer they become, whereas an SDD uses modules of flash memory, therefore there are no actually moving components. The access speeds for an SSD are much higher, which makes this kind of drives a preferred solution when speed is needed. That's why SSDs are in many cases used for the Operating System on a PC and for keeping data that is used frequently on web servers. Numerous providers also use a combination of the two drives, so they save the data on hard disk drives, but they use one or more SSDs 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 reduced since their disks have to spin less frequently to read and write.
SSD with Data Caching in Website Hosting
The cloud platform where we create website hosting accounts uses only SSD drives, so your web apps and static Internet sites will open very quickly. The SSDs are used for files, e-mails and databases, so no matter if you load a page or check for new messages using webmail, the content will load very quickly. So as to ensure even higher speeds, we also use multiple dedicated SSDs that function only as cache. All of the content which 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 improved efficiency. What we achieve this way aside from the improved speed is decreased overall load, thus lower potential for hardware failures, and extended lifespan of the main drives, that is one more level of protection for any information that you upload to your account.
