A solid-state drive is much quicker than any conventional hard disk. It is because an HDD uses spinning disks, which can rotate only so fast and the more data is read and written, the slower and hotter they get, at the same time an SDD employs modules of flash memory, hence there are no actually moving components. The access speeds for an SSD are a lot higher, which makes this kind of drives the best solution any time speed is needed. That's why SSDs are frequently employed for the Operating System on a PC and for keeping data that is accessed frequently on hosting servers. A lot of service providers also use a combination of the two drives, so they store the data on hard drives, but they use several solid-state drives to cache the more frequently used data and as a consequence, the data loads a lot faster while the load on the HDDs is lowered since their disks have to spin less often in order to read and write.
SSD with Data Caching in Cloud Hosting
The cloud platform where we create cloud hosting accounts uses solely SSD drives, so your web apps and static sites will open very quickly. The SSDs are used for files, email addresses and databases, so regardless if you open a page or check for new email messages using webmail, the content will load promptly. To ensure even greater speeds, we also use multiple dedicated SSDs that function only as cache. Any 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 much better performance. What we achieve this way in addition to the improved speed is reduced overall load, thus decreased potential for hardware failures, and longer lifespan of the primary drives, that is one more level of protection for any data 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 that employs exclusively SSD drives. We don't use HDDs anymore, so your Internet sites will load very quickly since we employ SSDs for each part of the service - files, databases and e-mail addresses. Considering that some customers may host Internet sites which are more popular than others, we also use multiple drives for caching. Our system detects all of the content that is accessed more often and duplicates it on these drives so as to load it from them. This setup is used for load-balancing purposes as we ensure that several reading/writing intensive Internet sites will not influence the performance of the other Internet sites that are stored on the same main drive. Using caching drives also increases the lifespan of the main storage SSDs and lowers the chance of disk failures.
