RAID in Cloud Hosting
The hard drives that we use for storage with our state-of-the-art cloud hosting platform are not the standard HDDs, but extremely fast solid-state drives (SSD). They operate in RAID-Z - a special setup developed for the ZFS file system that we work with. All of the content that you add to the cloud hosting account will be kept on multiple disk drives and at least one of them will be employed 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 stops working, it will be changed without service interruptions and the info will be recovered on the new drive by recalculating its bits using the data on the parity disk along with that on the other disks. This is done to guarantee the integrity of the info and together with the real-time checksum authentication which the ZFS file system executes on all drives, you'll never need to concern yourself with the loss of any data no matter what.
