RAID in Cloud Hosting
The hard disks that we use for storage with our state-of-the-art cloud web hosting platform are not the standard HDDs, but fast solid-state drives (SSD). They function in RAID-Z - a special setup designed for the ZFS file system which we use. Any content that you upload to the cloud hosting account will be saved on multiple hard drives and at least one shall be employed as a parity disk. This is a specific drive where an extra bit is included to any content copied on it. In case a disk in the RAID stops working, it will be replaced without any service disruptions and the information will be recovered on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the other disks. This is done so as to ensure the integrity of the data and along with the real-time checksum validation that the ZFS file system executes on all drives, you won't ever have to be concerned about the loss of any info no matter what.
RAID in Semi-dedicated Servers
In case you host your websites inside a semi-dedicated server account from our company, any content which you upload will be held on SSD drives which operate in RAID-Z. With this kind of RAID, at least 1 of the drives is employed for parity - when data is synchronized between the hard drives, an extra bit is included in it on the parity one. The idea behind this is to guarantee the integrity of the data which is cloned to a new drive if one of the hard drives in the RAID breaks down since the website content being copied on the brand new disk is recalculated from the data on the standard disk drives and on the parity one. An additional advantage of RAID-Z is that even in the event that a hard drive fails, the system can switch to a different one quickly without service interruptions of any type. RAID-Z adds one more level of protection for the content you upload on our cloud Internet hosting platform in addition to the ZFS file system that uses unique checksums to verify the integrity of every single file.
