RAID in Cloud Web Hosting
The hard drives which we use for storage with our top-notch cloud hosting platform are not the standard HDDs, but quick solid-state drives (SSD). They operate in RAID-Z - a special setup designed for the ZFS file system which we work with. All the content that you upload to the cloud web hosting account will be saved on multiple hard disks and at least 1 will be used 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 fails, it'll be changed without service interruptions and the data will be recovered on the new drive by recalculating its bits using the data on the parity disk plus that on the other disks. This is done to guarantee the integrity of the data and together with the real-time checksum validation that the ZFS file system executes on all drives, you won't ever need to be concerned about losing any info no matter what.
RAID in Semi-dedicated Servers
In case you host your sites in a semi-dedicated server account from our company, all the content that you upload will be held on SSD drives that work in RAID-Z. With this kind of RAID, at least 1 of the drives is used for parity - when data is synchronized between the disks, an extra bit is added to it on the parity one. The idea behind this is to ensure the integrity of the info which is duplicated to a new drive in case one of the drives in the RAID stops functioning because the content being copied on the new disk is recalculated from the data on the standard hard drives and on the parity one. Another advantage of RAID-Z is that even in case a disk drive stops functioning, the system can easily switch to a different one right away without service interruptions of any sort. RAID-Z adds one more level of protection for the content you upload on our cloud hosting platform in addition to the ZFS file system that uses unique checksums so as to authenticate the integrity of each file.
RAID in VPS Servers
The physical servers where we generate VPS server work with extremely fast SSD drives which will boost the speed of your sites significantly. The drives work in RAID to ensure that you won't lose any data as a result of a power loss or a hardware malfunction. The production servers work with many different drives where the information is stored and one disk is used for parity i.e. one bit is added to all of the info copied on it, that makes it much easier to recover the site content without loss in case a main drive stops working. In case you choose our backup service, the data will be stored on an independent machine which uses standard hard-disk drives and though there is no parity one in this case, they are also in a RAID to guarantee that we will have a backup of your website content all the time. With this type of configuration your data will always be safe because it will be available on multiple disk drives.
