A solid-state drive is considerably quicker than any conventional hard-disk drive. It is because a hard-disk drive 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 uses modules of flash memory, hence there are no physically moving components. The access speeds for an SSD are drastically higher, which makes this sort of drives the best solution in case speed is needed. Because of this SSDs are often employed for the Operating System on a computer system and for keeping data that's accessed regularly on web servers. Numerous service providers also use a combination of the two drives, so they store the data on hard drives, but they use one or more solid-state drives so as to cache the more frequently used data and as a consequence, the data loads a lot faster while the load on the HDDs is reduced as their disks need to spin less frequently in order to read and write.
SSD with Data Caching in Hosting
The cloud platform where we make hosting accounts uses only SSD drives, so your web apps and static Internet sites will open extremely fast. The SSDs are used for files, e-mail addresses and databases, so regardless if you open a page or check for new messages using webmail, the content will load instantly. So as to ensure even greater speeds, we also use numerous dedicated SSDs that function only as cache. All 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 performance. What we achieve this way in addition to the improved speed is decreased overall load, thus lower possibility of hardware failures, and longer lifespan of the main drives, that is 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 provide are generated on a cloud platform which uses exclusively SSD drives. We do not use HDDs any longer, so your sites will load very quickly since we use SSDs for each aspect of the service - files, databases and e-mails. As some users may host websites which could be more frequently visited than others, we also use numerous drives for caching. Our system detects all of the content that is loaded more often 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 other sites that are stored on the same primary drive. Using caching drives also increases the lifespan of the main storage SSDs and decreases the chance of disk failures.
