RAID in Shared Web Hosting
The hard disks which we employ for storage with our ground-breaking cloud web hosting platform are not the traditional HDDs, but super fast solid-state drives (SSD). They work in RAID-Z - a special setup developed for the ZFS file system that we employ. All the content that you upload to the shared web hosting account will be stored on multiple hard disks and at least one of them shall be used as a parity disk. This is a special drive where an additional bit is included to any content copied on it. In the event that a disk in the RAID stops working, it will be changed without any service disruptions and the information 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 ensure the integrity of the information and along with the real-time checksum validation that the ZFS file system runs on all drives, you'll never have to concern yourself with the loss of any info no matter what.
RAID in Semi-dedicated Servers
The RAID type which we use for the cloud Internet hosting platform where your semi-dedicated server account shall be created is known as RAID-Z. What's different about it is that at least 1 of the disks is used as a parity drive. Put simply, whenever any kind of data is copied on this specific disk drive, one more bit is added to it and in the event that a problematic disk is replaced, the info that will be copied on it is a mix of the data on the remaining hard disks in the RAID and that on the parity one. It's done this way to guarantee that the information is intact. Throughout this process, your websites will be up and running normally since RAID-Z makes it possible for an entire drive to fail without causing any service disruptions and it simply uses one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to warrant that no data can get silently corrupted on our servers, you won't ever have to worry about the integrity of your files.
RAID in VPS Servers
If you take advantage of one of our VPS server plans, any content you upload will be stored on SSD drives which function in RAID. At least one drive is intended for parity so as to ensure the integrity of your information. In simple terms, this is a special drive where information is copied with one bit added to it. If a disk within the RAID stops working, your sites will continue working and when a new disk takes the place of the malfunctioning one, the bits of the data that will be duplicated on it are calculated by using the healthy and the parity drives. By doing this, any chance of corrupting data throughout the process is prevented. We also use regular hard disks which operate in RAID for storing backups, so in case you add this service to your VPS plan, your website content will be saved on multiple drives and you won't ever have to worry about its integrity even in the event of multiple drive breakdowns.
