RAID in Shared Hosting
Our advanced cloud Internet hosting platform where all shared hosting accounts are made uses super fast SSD drives rather than the traditional HDDs, and they work in RAID-Z. With this setup, several hard drives function together and at least a single one is a dedicated parity disk. Basically, when data is written on the remaining drives, it is duplicated on the parity one adding an extra bit. This is performed for redundancy as even if some drive fails or falls out of the RAID for whatever reason, the data can be rebuilt and verified using the parity disk and the data recorded on the other ones, thus nothing will be lost and there will be no service disturbances. This is one more level of security for your info together with the state-of-the-art ZFS file system which uses checksums to make sure that all of the data on our servers is undamaged and is not silently corrupted.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is kept on SSD drives which operate in RAID-Z. One of the drives in type of a setup is used for parity - whenever data is cloned on it, an extra bit is added. In case a disk happens to be defective, it will be taken out of the RAID without interrupting the operation of the sites because the data will load from the rest of the drives, and when a new drive is added, the info that will be duplicated on it will be a combination between the data on the parity disk and data saved on the other drives in the RAID. This is done so as to ensure that the info which is being duplicated is accurate, so the moment the new drive is rebuilt, it could be incorporated into the RAID as a production one. This is an extra warranty for the integrity of your information as the ZFS file system that runs on our cloud web hosting platform analyzes a special checksum of all the copies of your files on the various drives to be able to avoid any probability of silent data corruption.
