RAID in Shared Web Hosting
The hard disks 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 employ. All the content that you upload to your shared web hosting account will be saved on multiple hard disks and at least one shall be used as a parity disk. This is a special drive where a further bit is included to any content copied on it. In the event that a disk in the RAID fails, it will be replaced with no service disruptions and the info will be rebuilt 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 so as to guarantee the integrity of the info and together with the real-time checksum authentication that the ZFS file system performs on all drives, you'll never need to concern yourself with the loss of any data no matter what.
RAID in Semi-dedicated Servers
The RAID type that we employ for the cloud web hosting platform where your semi-dedicated server account will be created is named RAID-Z. What's different about it is that at least one of the disks is employed as a parity drive. Simply put, whenever any data is copied on this special hard drive, one more bit is added to it and in case a malfunctioning disk is changed, the data that will be duplicated on it is a combination of the data on the other hard disks in the RAID and that on the parity one. It's done this way to ensure that your info is intact. During this process, your Internet sites will be working normally because RAID-Z allows for an entire drive to fail without causing any service disturbances and it simply works by using one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to warrant that no data will get silently corrupted on our servers, you won't have to worry about the integrity of your files.
