A solid-state drive is really faster than any regular hard-disk drive. The reason is that an HDD works by using rotating disks, which can rotate only so fast and the more data is read and written, the slower and warmer they become, while an SDD operates with modules of flash memory, so there aren't any physically moving parts. The access speeds for an SSD are considerably higher, which makes this sort of drives the best solution when speed is needed. Because of this SSDs are often used for the Operating System on a desktop or notebook and for storing data that is accessed regularly on web servers. A lot of providers also use a combination of the two drives, so they store the data on hard disk drives, but they use several SSDs so as to cache the more often used data and due to this fact, the data loads a lot quicker while the load on the HDDs is decreased because their disks need to spin less often in order to read and write.
SSD with Data Caching in Web Hosting
If you host your websites in a web hosting account from us, you will notice their fantastic performance. This is because our cloud platform uses exclusively SSD drives for all files, e-mails and databases and we don't use HDDs for any part of the web hosting service. Along with the leading-edge ZFS file system, this setup will raise the speed of your sites considerably. For load-balancing, we also use a number of SSDs for caching purposes only. Any content that generates increased traffic or causes plenty of reading/writing processes is copied on them automatically, so the load on the main drives will be lower, thus the overall performance of all Internet sites hosted on our end will improve. The abovementioned subsequently prolongs the life of the main drives and decreases the potential for a disk failure, that is a further guarantee for the integrity of any content that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we provide are generated on a cloud platform that employs exclusively SSD drives. We don't use HDDs any longer, so your websites will load quickly as we use SSDs for each aspect of the service - files, databases and emails. Considering that some users may host sites which could be more popular than others, we also use multiple drives for caching. Our system detects all of the content that is accessed more frequently and copies 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 sites will not influence the performance of the rest of the Internet sites which are stored on the very same main drive. Using caching drives also raises the life-span of the main storage SSDs and lowers the potential for disk failures.
