A solid-state drive is noticeably faster than any standard hard-disk drive. This is because a hard-disk drive uses rotating disks, that can rotate only so fast and the more information is read and written, the sluggish and hotter they get, while an SDD operates with modules of flash memory, so there aren't any physically moving components. The access speeds for an SSD are considerably higher, which makes this sort of drives the best solution any time speed is needed. Because of this SSDs are frequently used for the Operating System on a personal computer and for keeping data which is accessed frequently on web servers. A lot of service providers also use a combination of the two drives, so they store the data on hard-disks, but they use several solid-state drives in order to cache the more often used data and because of that, the data loads faster while the load on the HDDs is decreased as their disks have to spin less frequently 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 Internet sites will load 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-mails through webmail, the content will load promptly. So as to offer even higher speeds, we also use multiple dedicated SSDs that work only as cache. All content which 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 improved performance. What we achieve this way aside from the better speed is lowered overall load, thus lower possibility of hardware failures, and longer lifespan of the primary drives, which is one more level of protection for any info that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we provide are generated on a cloud platform which uses only SSD drives. We don't use HDDs any longer, so your Internet sites will load quickly because we use SSDs for each aspect of the service - files, databases and email addresses. As some people may host sites that are more popular than others, we also use many drives for caching. Our system finds all the content which is loaded more regularly and clones it on these drives so as to load it from them. This configuration is used for load-balancing purposes as we guarantee that several reading/writing intensive Internet sites will not influence the performance of the rest of the Internet sites which are stored on the same primary drive. Using caching drives also raises the lifespan of the main storage SSDs and lowers the probability of disk failures.
