A solid-state drive (SSD) boosts the performance of every app running on it compared to a common hard-disk drive (HDD). The reason is that a solid-state drive uses a number of interconnected flash memory modules, so there are no physical parts to move. In comparison, a hard disk uses spinning disks and each reading or writing process causes the disks to move, meaning the speed of an HDD is fixed. Because the cost of the two types of drives also differ, a lot of personal computers and web servers are equipped with an SSD for the operating system and random applications, and a hard disk for file storage, thus balancing price and overall performance. A hosting service provider may also use an SSD for caching purposes, so files which are used very often will be saved on this type of a drive for achieving better loading speeds and for limiting the reading/writing processes on the HDDs.
SSD with Data Caching in Cloud Web Hosting
The cloud platform where we make cloud web hosting accounts uses solely SSD drives, so your web applications and static Internet sites will load very fast. The SSDs are used for files, emails and databases, so regardless of whether you open a page or check for new emails using webmail, the content will load right away. To ensure even greater 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 read from them and not from the main storage drives. Of course, that content is replaced dynamically for improved performance. What we achieve this way aside from the improved speed is lowered overall load, thus reduced potential for hardware failures, and longer lifespan of the primary drives, that is one more level of security for any info that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we offer are created on a cloud platform which uses solely SSD drives. We don't use HDDs anymore, so your websites will load extremely fast since we employ SSDs for every aspect of the service - files, databases and e-mails. Considering that some customers may host Internet sites which could be more popular than others, we also use multiple drives for caching. Our system finds any content that is loaded 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 websites will not influence the performance of the rest of the sites which are stored on the same main drive. Using caching drives also increases the lifespan of the main storage SSDs and decreases the possibility of disk failures.
