RAID in Shared Hosting
The revolutionary cloud web hosting platform where all shared hosting accounts are created uses super fast SSD drives rather than the traditional HDDs, and they function in RAID-Z. With this configuration, a number of hard drives work together and at least 1 is a dedicated parity disk. Basically, when data is written on the rest of the drives, it's duplicated on the parity one adding an extra bit. This is performed for redundancy as even in case some drive fails or falls out of the RAID for some reason, the info can be rebuilt and verified using the parity disk and the data stored on the other ones, thus practically nothing will be lost and there won't be any service disorders. This is an additional level of protection for your data together with the top-notch ZFS file system which uses checksums to make sure that all data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is saved on SSD drives which operate in RAID-Z. One of the drives in such a configuration is used for parity - every time data is cloned on it, an additional bit is added. In case a disk happens to be flawed, it will be taken out of the RAID without disturbing the operation of the websites because the data will load from the remaining drives, and when a new drive is added, the data which will be cloned on it will be a combination between the info on the parity disk and data kept on the other hard disks in the RAID. That is done to ensure that the data which is being copied is accurate, so the moment the new drive is rebuilt, it could be integrated into the RAID as a production one. This is an extra guarantee for the integrity of your info since the ZFS file system that runs on our cloud web hosting platform compares a special checksum of all the copies of the files on the separate drives in order to avoid any probability of silent data corruption.
