A solid-state drive (SSD) enhances the performance of each application running on it compared to a common hard-disk drive (HDD). The reason is that a solid-state drive employs a variety of interconnected flash memory units, so there are no physical parts to move. In comparison, a hard disk uses spinning disks and every reading or writing process causes the disks to spin, so the speed of an HDD is restricted. Since the cost of the two kinds of drives are different as well, a lot of PCs and web servers are provided with an SSD for the operating system and random applications, and a hard disk for data storage, this way balancing price and effectiveness. A website hosting provider could also use an SSD for caching purposes, so files that are accessed frequently will be saved on this type of a drive for reaching better loading speeds and for minimizing the reading/writing processes on the hard drives.
SSD with Data Caching in Cloud Hosting
If you host your sites in a cloud hosting account from our company, you'll definitely notice their fantastic performance. The reason is that 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 website hosting service. Together with the revolutionary ZFS file system, this configuration will boost the speed of your websites substantially. For load-balancing, we also use multiple SSDs for caching purposes only. All of the content that generates increased traffic or creates lots of reading/writing processes is copied on them promptly, so that the load on the primary drives will be lower, thus the overall performance of all websites hosted with us will improve. The latter in turn prolongs the life of the main drives and decreases the possibility of a disk failure, which is an additional warranty for the reliability of any content which 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 which uses exclusively SSD drives. We don't use HDDs anymore, so your Internet sites will load very quickly since we employ SSDs for each aspect of the service - files, databases and e-mails. As some people may host Internet sites that could be more popular than others, we also use many drives for caching. Our system identifies all the content that is accessed more regularly and clones it on these drives so as to load it from them. This setup is used for load-balancing purposes as we make sure that several reading/writing intensive sites will not affect the performance of the rest of the sites which are stored on the same main drive. Using caching drives also increases the life-span of the main storage SSDs and decreases the probability of disk failures.
