A solid-state drive is really quicker than any normal hard-disk drive. This is because an HDD employs spinning disks, that can rotate only so fast and the more data is read and written, the sluggish and hotter they become, at the same time an SDD works with modules of flash memory, therefore there are no physically moving parts. The access speeds for an SSD are substantially higher, which makes this kind of drives a recommended solution any time speed is needed. That's why SSDs are often used for the Operating System on a laptop or computer and for keeping data that's used repeatedly on servers. A large number of providers also use a combination of both drives, so they save the data on hard-disks, but they use several SSDs in order to cache the more often used data and consequently, the data loads quicker while the load on the HDDs is lowered because their disks have to spin less frequently in order to read and write.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we provide are generated on a cloud platform that employs only SSD drives. We don't use HDDs any longer, so your Internet sites will load amazingly quickly since we employ SSDs for each aspect of the service - files, databases and e-mail addresses. Considering that some people may host Internet sites that can be more popular than others, we also use a number of drives for caching. Our system discovers all the content which is loaded more often and clones it on these drives in order to load it from them. This configuration is used for load-balancing purposes as we make sure that several reading/writing intensive sites will not affect the performance of the other websites that are stored on the very same primary drive. Using caching drives also raises the life-span of the main storage SSDs and decreases the probability of disk failures.
