RAID in Website Hosting
All the content which you upload to your new website hosting account will be saved on quick SSD drives which operate in RAID-Z. This configuration is built to use the ZFS file system that runs on our cloud web hosting platform and it adds another level of security for your site content on top of the real-time checksum authentication that ZFS uses to guarantee the integrity of the data. With RAID-Z, the information is saved on a couple of disks and at least one is a parity disk - whenever info is recorded on it, an extra bit is added, so in the event that any drive stops functioning for whatever reason, the stability of the information can be verified by recalculating its bits based on what is stored on the production hard drives and on the parity one. With RAID-Z, the operation of our system will never be interrupted and it'll continue functioning efficiently until the problematic drive is changed and the information is synchronized on it.
RAID in Semi-dedicated Servers
The information uploaded to any semi-dedicated server account is saved on SSD drives which function in RAID-Z. One of the drives in this kind of a configuration is used for parity - every 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 interrupting the work of the Internet sites because the data will load from the other drives, and when a brand new drive is included, the info which will be cloned on it will be a combination between the info on the parity disk and data kept on the other hard drives in the RAID. That is done so as to ensure that the data which is being duplicated is correct, so the moment the new drive is rebuilt, it can be included in the RAID as a production one. This is an extra warranty for the integrity of your data as the ZFS file system that runs on our cloud hosting platform analyzes a special checksum of all of the copies of your files on the separate drives to avoid any possibility of silent data corruption.
