RAID in Web Hosting
All of the content which you upload to your new web hosting account will be held on fast SSD drives that operate in RAID-Z. This configuration is built to use the ZFS file system that runs on our cloud hosting platform and it adds one more level of protection for your website content in addition to the real-time checksum authentication that ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on several disks and at least 1 is a parity disk - whenever information is written on it, an additional bit is added, so if any drive stops working for some reason, the stability of the data can be verified by recalculating its bits based on what is saved on the production drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue working flawlessly until the faulty drive is changed and the info is synchronized on it.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is stored on SSD drives that operate in RAID-Z. One of the drives in this kind of a configuration is used for parity - whenever data is cloned on it, an additional bit is added. If a disk turns out to be flawed, it will be taken out of the RAID without disturbing the functioning of the websites because the data will load from the rest of the drives, and when a brand new drive is included, the data that will be cloned on it will be a combination between the info on the parity disk and data stored on the other drives in the RAID. That is done so as to ensure that the data which is being copied is accurate, so as soon as the new drive is rebuilt, it can be included in the RAID as a production one. This is one more 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 various drives to avoid any chance of silent data corruption.
