A solid-state drive is incredibly quicker than any conventional hard-disk drive. The reason is that an HDD employs rotating disks, that can rotate only so fast and the more information is read and written, the slower and hotter they get, at the same time an SDD employs modules of flash memory, so there are no physically moving components. The access speeds for an SSD are much higher, which makes this type of drives a recommended solution every time speed is needed. This is the reason why SSDs are frequently employed for the Operating System on a personal computer and for saving data that is used regularly on web servers. A large number of providers also use a combination of the two drives, so they save the data on HDDs, but they use several solid-state drives so as to cache the more often used data and as a result, the data loads a lot faster while the load on the HDDs is decreased because their disks have to spin less often in order to read and write.
SSD with Data Caching in Shared Website Hosting
The cloud platform where we make shared website hosting accounts uses solely SSD drives, so your web apps and static websites will load extremely fast. The SSDs are used for files, e-mails and databases, so no matter if you load a page or check for new e-mails with webmail, the content will load quickly. To ensure even greater speeds, we also use a number of dedicated SSDs which function only as cache. All content that 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 better performance. What we achieve that way except for the improved speed is reduced overall load, thus decreased probability of hardware failures, and extended lifespan of the primary drives, that's one more level of protection for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we offer are generated on a cloud platform which employs only SSD drives. We don't use HDDs any longer, so your sites will load extremely fast since we use SSDs for every part of the service - files, databases and e-mail addresses. As some users may host sites which are more popular than others, we also use many drives for caching. Our system finds all of the content which is loaded more regularly and duplicates it on these drives so as to load it from them. This setup is used for load-balancing purposes as we guarantee that several reading/writing intensive Internet sites will not affect the performance of the rest of the Internet sites that are stored on the very same primary drive. Using caching drives also raises the lifespan of the main storage SSDs and reduces the potential for disk failures.
