RAID in Website Hosting
The advanced cloud Internet hosting platform where all website hosting accounts are generated uses quick SSD drives as opposed to the standard HDDs, and they operate in RAID-Z. With this setup, numerous hard disk drives operate together and at least one of them is a dedicated parity disk. Put simply, when data is written on the rest of the drives, it is duplicated on the parity one adding an extra bit. This is done for redundancy as even if some drive fails or falls out of the RAID for some reason, the information can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, so absolutely nothing will be lost and there will be no service disturbances. This is another level of security for your info together with the cutting-edge ZFS file system that uses checksums to ensure that all the data on our servers is intact and is not silently corrupted.
RAID in VPS Hosting
The SSD drives which we use on the machines where we create virtual private servers operate in RAID to ensure that any content you upload will be available and intact all of the time. At least one drive is employed for parity - one bit of info is added to any data copied on it. In the event that a main drive breaks down, it is changed and the information that will be duplicated on it is calculated between the rest of the drives and the parity one. This is done to ensure that the right information is copied and that not a single file is corrupted as the new drive will be included in the RAID afterwards. Also, we use hard disk drives operating in RAID on the backup servers, so in case you add this upgrade to your VPS plan, you'll use an even more reliable web hosting service because your content will be available on multiple drives irrespective of any sort of sudden hardware failure.
