A solid-state drive is incredibly quicker than any conventional hard disk. This is because an HDD employs spinning disks, that can rotate only so fast and the more information is read and written, the sluggish and hotter they become, while an SDD employs modules of flash memory, hence there aren't any physically moving components. The access speeds for an SSD are substantially higher, which makes this type of drives the best solution when speed is needed. That's why SSDs are frequently employed for the Operating System on a PC and for saving data which is used regularly on hosting servers. A large number of service providers also use a combination of the two drives, so they store the data on hard-disks, but they use a couple of solid-state drives so as to cache the more often used data and due to this fact, the data loads much quicker while the load on the HDDs is lowered because their disks need to spin less often in order to read and write.
SSD with Data Caching in Cloud Hosting
The cloud platform where we make cloud hosting accounts uses exclusively SSD drives, so your web apps and static websites will load very fast. The SSDs are used for files, e-mails and databases, so regardless if you load a page or check for new messages using webmail, the content will load instantly. In order to ensure even higher speeds, we also use a group of dedicated SSDs which function only as cache. All content which generates lots of traffic is copied on them automatically and is later read from them and not from the main storage drives. Needless to say, that content is replaced dynamically for better efficiency. What we achieve in this way except for the improved speed is lowered overall load, thus decreased possibility of hardware failures, and longer lifespan of the main drives, which is one more level of protection for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we provide are made on a cloud platform that employs exclusively SSD drives. We do not use HDDs any longer, so your sites will load very quickly because we employ SSDs for all aspects of the service - files, databases and e-mails. As some customers may host sites that could be more frequently visited than others, we also use multiple drives for caching. Our system finds all the content which is accessed more often and clones it on these drives in order to load it from them. This setup is used for load-balancing purposes as we ensure that several reading/writing intensive sites will not affect the performance of the rest of the sites which are stored on the same primary drive. Using caching drives also raises the lifespan of the main storage SSDs and reduces the probability of disk failures.
