A solid-state drive is significantly quicker than any standard hard disk. This is because a hard-disk drive works by using spinning disks, that can rotate only so fast and the more information is read and written, the sluggish and hotter they get, while an SDD uses modules of flash memory, so there aren't any physically moving parts. The access speeds for an SSD are substantially higher, which makes this sort of drives a recommended solution every time speed is needed. That's why SSDs are often used for the Operating System on a PC and for keeping data that's used frequently on servers. Many providers also use a combination of both 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 a lot quicker while the load on the HDDs is lowered because their disks have to spin less frequently in order 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 applications and static websites will open very quickly. The SSDs are used for files, e-mail addresses and databases, so regardless of whether you load a page or check for new e-mail messages using webmail, the content will load without delay. In order to ensure even better speeds, we also use a number of dedicated SSDs that function only as cache. All of the content which generates a lot 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 decreased overall load, thus decreased probability of hardware failures, and extended lifespan of the primary drives, which is one more level of protection for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
In case you need speed and fantastic performance for your sites, our semi-dedicated server accounts shall be a very suitable solution since they're created on a cloud platform which employs SSDs for each aspect of the service - e-mails, databases and files. That way, each and every website that you host here will load fast. Just like other providers, we also use SSDs for caching, but since all storage drives are solid-state ones, you will be able to take advantage of the good performance all of the time and regardless of the nature of your sites. The caching drives are used for load-balancing and any frequently accessed content is copied to them, which both lowers the load and provides the good performance of all websites that load from the primary drives. The lifespan of the latter is also increased because there'll be substantially less reading and writing processes on them.
