RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is stored on SSD drives which function in RAID-Z. One of the drives in this kind of a configuration is used for parity - each time data is cloned on it, an extra bit is added. In case a disk turns out to be defective, it will be taken out of the RAID without disturbing the operation of the sites because the data will load from the other drives, and when a brand new drive is added, the data that will be cloned on it will be a combination between the data on the parity disk and data stored on the other hard drives in the RAID. That is done in order to guarantee that the information that is being cloned is correct, so as soon as the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is an extra guarantee for the integrity of your info since the ZFS file system which runs on our cloud Internet hosting platform compares a unique checksum of all of the copies of your files on the different drives so as to avoid any chance of silent data corruption.
