A solid-state drive is really faster than any normal hard disk. This is because an HDD uses spinning disks, which can rotate only so fast and the more info is read and written, the sluggish and warmer they get, while an SDD takes advantage of modules of flash memory, so there are no actually moving parts. The access speeds for an SSD are drastically higher, which makes this sort of drives a recommended solution every time speed is needed. That's why SSDs are in many cases employed for the Operating System on a desktop or notebook and for keeping data that's accessed often on web servers. Many service providers also use a combination of both drives, so they keep the data on hard drives, but they use a couple of SSDs so as to cache the more frequently used data and because of this, the data loads much quicker while the load on the HDDs is decreased since their disks have to spin less often in order to read and write.
SSD with Data Caching in Semi-dedicated Servers
In case you obtain one of our semi-dedicated server plans, your Internet sites will be stored on a cloud platform that employs solely SSD drives for the storing of files, databases and e-mail messages. Together with the cutting-edge ZFS file system that we use, this configuration provides very fast loading speed for each web app hosted on our end. To guarantee that the sites of one customer don't affect the ones of another, we also use multiple SSDs as cache - our system finds files that are accessed more frequently and duplicates them, so that they start loading from the caching drives. The content on the latter is updated dynamically and for that reason we can balance the load on all drives, warrant their extended life-span, decrease the risk of disk failures and, of course, supply a quick and reliable Internet hosting service.
