A solid-state drive is really faster than any conventional hard disk. It is because an HDD employs rotating disks, which can rotate only so fast and the more information is read and written, the sluggish and hotter they become, whereas an SDD works with modules of flash memory, so there aren't any physically moving components. The access speeds for an SSD are a lot higher, which makes this sort of drives an ideal solution if speed is needed. Because of this SSDs are frequently used for the Operating System on a computer system and for saving data which is accessed repeatedly on servers. A lot of service providers also use a combination of both drives, so they save the data on hard drives, but they use one or more SSDs so as to cache the more often used data and because of this, the data loads a lot faster while the load on the HDDs is reduced as their disks need to spin less frequently in order to read and write.
SSD with Data Caching in Shared Hosting
The cloud platform where we create shared hosting accounts uses solely SSD drives, so your web apps and static websites will load extremely fast. The SSDs are used for files, emails and databases, so regardless of whether you load a page or check for new emails with webmail, the content will load immediately. So as to ensure even greater speeds, we also use multiple dedicated SSDs that function only as cache. All of the content that generates lots of traffic is copied on them automatically and is later read from them and not from the primary storage drives. Of course, that content is replaced dynamically for better performance. What we achieve that way except for the improved speed is lowered overall load, thus reduced potential for hardware failures, and longer lifespan of the main drives, that's one more level of security for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we provide are made on a cloud platform which employs solely SSD drives. We do not use HDDs anymore, so your Internet sites will load very quickly because we use SSDs for all aspects of the service - files, databases and e-mails. Considering that some people may host sites that can be more frequently visited than others, we also use many drives for caching. Our system identifies any content that is loaded more often and copies 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 affect the performance of the other websites that are stored on the same main drive. Using caching drives also raises the life-span of the main storage SSDs and reduces the possibility of disk failures.
