A solid-state drive (SSD) enhances the performance of every application running on it when compared to a common hard-disk drive (HDD). The reason is that a solid-state drive functions with a variety of interconnected flash memory units, so there're no physical parts to move. In contrast, an HDD employs spinning disks and every reading or writing process causes the disks to rotate, which means that the speed of an HDD is limited. Because the cost of the two types of drives are different as well, numerous PCs and web servers are equipped with an SSD for the operating system and random applications, and a hard-disk drive for file storage, thus balancing cost and overall performance. An Internet hosting service provider may also use an SSD for caching purposes, so files which are used regularly will be held on this type of a drive for accomplishing improved loading speeds and for limiting the reading/writing processes on the hard drives.
SSD with Data Caching in Hosting
The cloud platform where we create hosting accounts uses solely SSD drives, so your web apps and static Internet sites will open very 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 through webmail, the content will load right away. To offer even higher speeds, we also use multiple dedicated SSDs that work only as cache. Any content which generates lots of traffic is copied on them automatically and is later on read from them and not from the primary storage drives. Of course, that content is replaced dynamically for improved performance. What we achieve in this way except for the improved speed is reduced overall load, thus lower potential for hardware failures, and longer lifespan of the primary drives, that's one more level of security for any info that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we offer are created on a cloud platform which uses exclusively SSD drives. We do not use HDDs anymore, so your Internet sites will load quickly because we employ SSDs for each part of the service - files, databases and e-mails. Considering that some users may host sites that could be more frequently visited than others, we also use a number of drives for caching. Our system detects all the content which is loaded more often and duplicates it on these drives in order to load it from them. This setup is used for load-balancing purposes as we ensure that several reading/writing intensive sites will not influence the performance of the other Internet sites that are stored on the same main drive. Using caching drives also raises the life-span of the main storage SSDs and reduces the probability of disk failures.
