A solid-state drive is substantially faster than any normal hard-disk drive. The reason is that an HDD uses rotating disks, that can rotate only so fast and the more information is read and written, the slower and hotter they get, while an SDD employs modules of flash memory, therefore there aren't any actually moving components. The access speeds for an SSD are significantly higher, which makes this sort of drives an ideal solution when speed is needed. This is the reason why SSDs are often employed for the Operating System on a personal computer and for saving data that's accessed regularly on servers. Numerous providers also use a combination of both drives, so they save the data on hard drives, but they use several SSDs in order to cache the more often used data and for that reason, the data loads a lot faster while the load on the HDDs is lowered because their disks have to spin less frequently in order to read and write.
SSD with Data Caching in Website Hosting
If you host your Internet sites in a website hosting account from us, you will notice their fantastic performance. This is because our cloud platform uses solely SSD drives for all of the files, emails and databases and we do not use HDDs for any part of the web hosting service. In addition to the advanced ZFS file system, this configuration will raise the speed of your sites tremendously. For load-balancing, we also use multiple SSDs for caching purposes only. All content that generates increased traffic or causes plenty of reading/writing processes is copied on them instantly, so that the load on the main drives will be reduced, thus the overall performance of all sites hosted on our end will be better. The abovementioned in turn prolongs the life of the main drives and lessens the potential for a disk failure, which is an additional warranty for the reliability of any content 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 exclusively SSD drives. We don't use HDDs any longer, so your sites will load amazingly quickly as we employ SSDs for all aspects of the service - files, databases and email addresses. Considering that some users may host websites which can be more popular than others, we also use many drives for caching. Our system finds any content which is accessed more often and duplicates it on these drives in order to load it from them. This configuration is used for load-balancing purposes as we guarantee that several reading/writing intensive sites will not affect the performance of the other 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.
