RAID in Cloud Web Hosting
The drives that we employ for storage with our innovative cloud web hosting platform are not the traditional HDDs, but extremely fast solid-state drives (SSD). They work in RAID-Z - a special setup created for the ZFS file system which we use. All the content that you add to your cloud web hosting account will be kept on multiple hard drives and at least 1 will be used as a parity disk. This is a specific drive where an additional bit is included to any content copied on it. In case a disk in the RAID fails, it'll be replaced with no service disturbances and the info will be rebuilt on the new drive by recalculating its bits thanks to the data on the parity disk plus that on the other disks. This is done so as to ensure the integrity of the data and along with the real-time checksum authentication that the ZFS file system performs on all drives, you will never have to be concerned about losing any information no matter what.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is stored on SSD drives which work in RAID-Z. One of the drives in type of a configuration is used for parity - whenever data is cloned on it, an additional bit is added. If a disk turns out to be flawed, it will be removed from the RAID without disturbing the work of the sites as the data will load from the remaining drives, and when a new drive is included, the data that will be duplicated on it will be a blend between the data on the parity disk and data kept on the other hard drives in the RAID. This is done so as to guarantee that the info that is being duplicated is accurate, so the moment the new drive is rebuilt, it could be integrated into the RAID as a production one. This is one more warranty for the integrity of your data since the ZFS file system which runs on our cloud web hosting platform analyzes a special checksum of all the copies of your files on the different drives so as to avoid any chance of silent data corruption.
