A solid-state drive is incredibly faster than any normal hard disk. The reason is that a hard-disk drive employs spinning disks, which can rotate only so fast and the more data is read and written, the slower and warmer they get, at the same time an SDD employs modules of flash memory, therefore there are no actually moving components. The access speeds for an SSD are a lot higher, which makes this type of drives the best solution every time speed is needed. Because of this SSDs are in many cases employed for the Operating System on a laptop or computer and for keeping data that is accessed frequently on web servers. A lot of providers also use a combination of both 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 consequence, the data loads a lot faster while the load on the HDDs is lowered as their disks have to spin less frequently in order to read and write.
SSD with Data Caching in Cloud Website Hosting
The cloud platform where we create cloud website hosting accounts uses solely SSD drives, so your web apps and static websites will open very quickly. The SSDs are used for files, e-mail addresses and databases, so regardless if you open a page or check for new e-mails with webmail, the content will load very quickly. So as to ensure even better speeds, we also use numerous dedicated SSDs that function only as cache. Any content that generates a lot of traffic is copied on them automatically and is afterwards read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for better efficiency. What we achieve by doing this apart from the improved speed is decreased overall load, thus lower possibility of hardware failures, and prolonged lifespan of the main drives, that's 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 created on a cloud platform which uses only SSD drives. We don't use HDDs any longer, so your websites will load extremely fast because we use SSDs for every part of the service - files, databases and e-mails. As some people may host websites that are more popular than others, we also use multiple drives for caching. Our system detects any content that is loaded more regularly and copies it on these drives so as to load it from them. This setup is used for load-balancing purposes as we ensure that several reading/writing intensive sites will not influence the performance of the rest of the 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 chance of disk failures.
