A solid-state drive (SSD) improves the performance of each application running on it compared with a regular hard-disk drive (HDD). The reason is that a solid-state drive functions with many different interconnected flash memory units, so there're no physical parts to move. In contrast, a hard disk employs spinning disks and any reading or writing process causes the disks to rotate, so the speed of an HDD is fixed. Since the cost of the two kinds of drives also differ, numerous personal computers and web servers are provided with an SSD for the operating system and random applications, and an HDD for file storage, thus balancing price and performance. An Internet hosting service provider can also use an SSD for caching purposes, which means that files which are used on a regular basis will be held on such a drive for accomplishing higher loading speeds and for limiting the reading/writing processes on the hard drives.
SSD with Data Caching in Shared Web Hosting
The cloud platform where we create shared web hosting accounts uses exclusively SSD drives, so your web applications and static websites will load extremely fast. The SSDs are used for files, e-mail addresses and databases, so no matter if you load a page or check for new e-mails using webmail, the content will load promptly. To offer even better speeds, we also use multiple dedicated SSDs that work only as cache. All of the content that generates a lot of traffic is copied on them automatically and is later read from them and not from the main storage drives. Of course, that content is replaced dynamically for better performance. What we achieve this way aside from the improved speed is decreased overall load, thus lower possibility of hardware failures, and extended lifespan of the primary drives, that is one more level of protection for any info 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 uses exclusively SSD drives. We don't use HDDs any longer, so your Internet sites will load amazingly quickly because we employ SSDs for all aspects of the service - files, databases and e-mails. Considering that some users may host sites that are more frequently visited than others, we also use numerous drives for caching. Our system identifies any content that is accessed more frequently 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 websites will not affect the performance of the rest of the Internet sites which are stored on the very same main drive. Using caching drives also increases the life-span of the main storage SSDs and decreases the possibility of disk failures.
