A solid-state drive is substantially quicker than any regular hard disk. The reason is that an HDD employs rotating disks, which can rotate only so fast and the more information is read and written, the slower and hotter they become, at the same time an SDD operates with modules of flash memory, therefore there are no physically moving parts. The access speeds for an SSD are substantially higher, which makes this sort of drives the right solution if speed is needed. This is the reason why SSDs are frequently used for the Operating System on a computer system and for saving data which is accessed regularly on servers. A large number of service providers also use a combination of both drives, so they keep the data on hard-disks, but they use several solid-state drives to cache the more often used data and consequently, the data loads quicker while the load on the HDDs is decreased as their disks need to spin less often to read and write.
SSD with Data Caching in Shared Hosting
In case you host your websites in a shared hosting account with us, you'll notice their exceptional performance. The reason is that our cloud platform uses only SSD drives for all of the files, email addresses and databases and we don't use HDDs for any part of the Internet hosting service. Along with the cutting-edge ZFS file system, this configuration will increase the speed of your sites significantly. For load-balancing, we also use multiple SSDs for caching purposes only. All of the content which generates more traffic or causes lots of reading/writing processes is copied on them promptly, so that the load on the main drives will be reduced, thus the overall performance of all websites hosted on our end will be better. The abovementioned subsequently prolongs the life of the primary drives and decreases the possibility of a disk failure, which is another guarantee 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 made on a cloud platform that employs exclusively SSD drives. We do not use HDDs any longer, so your sites will load quickly as we use SSDs for each part of the service - files, databases and e-mail addresses. As some users may host websites which could be more frequently visited than others, we also use multiple drives for caching. Our system detects all the content which is accessed more often and copies 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 rest of the sites which are stored on the same primary drive. Using caching drives also increases the life-span of the main storage SSDs and decreases the potential for disk failures.
