A solid-state drive is significantly faster than any standard hard-disk drive. It is because an HDD uses spinning disks, which can rotate only so fast and the more info is read and written, the slower and hotter they get, while an SDD works with modules of flash memory, therefore there aren't any actually moving components. The access speeds for an SSD are substantially higher, which makes this kind of drives a preferred solution when speed is needed. That's why SSDs are frequently used for the Operating System on a home PC and for keeping data that is accessed regularly on hosting servers. Numerous service providers also use a combination of the two drives, so they store the data on hard disk drives, but they use one or more SSDs so as to cache the more frequently used data and because of this, the data loads a lot faster while the load on the HDDs is reduced because their disks need to spin less often in order to read and write.
SSD with Data Caching in Shared Hosting
If you host your sites in a shared hosting account with us, you will notice their fantastic performance. This is because our cloud platform uses only SSD drives for all the files, email addresses and databases and we don't use HDDs for any part of the web hosting service. Together with the innovative ZFS file system, this setup will raise the speed of your sites substantially. For load-balancing, we also use a number of SSDs for caching purposes only. Any content which generates increased traffic or creates plenty of reading/writing processes is duplicated on them automatically, so that the load on the primary drives will be lower, thus the overall performance of all Internet sites hosted on our end will be better. The abovementioned in turn prolongs the life of the main drives and reduces the possibility of a disk failure, which is one more warranty for the integrity of all content which 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 that employs only SSD drives. We do not use HDDs any longer, so your Internet sites will load very quickly as we employ SSDs for every part of the service - files, databases and e-mails. Considering that some people may host websites which are more popular than others, we also use many drives for caching. Our system discovers all of the content that is accessed more often and copies it on these drives so as to load it from them. This configuration is used for load-balancing purposes as we make sure that several reading/writing intensive sites will not influence the performance of the other Internet sites which are stored on the very same primary drive. Using caching drives also raises the lifespan of the main storage SSDs and lowers the chance of disk failures.
