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 Shared Hosting
The cloud platform where we make shared hosting accounts uses only SSD drives, so your web applications and static websites will load very quickly. The SSDs are used for files, e-mails and databases, so regardless of whether you open a page or check for new messages through webmail, the content will load quickly. In order to ensure even greater speeds, we also use multiple dedicated SSDs that work only as cache. All content that generates lots of traffic is copied on them automatically and is later read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for much better performance. What we achieve this way aside from the improved speed is lowered overall load, thus reduced possibility of hardware failures, and longer lifespan of the main drives, that is one more level of security for any information that you upload to your account.
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.
