RAID in Website Hosting
The advanced cloud web hosting platform where all website hosting accounts are created employs fast SSD drives as an alternative to the standard HDDs, and they function in RAID-Z. With this setup, a number of hard disk drives work together and at least 1 is a dedicated parity disk. Basically, when data is written on the other drives, it's 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 info can be rebuilt and verified thanks to the parity disk and the data stored on the other ones, so not a single thing will be lost and there won't be any service interruptions. This is one more level of protection for your data in addition to 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 Semi-dedicated Hosting
The RAID type that we use for the cloud Internet hosting platform where your semi-dedicated hosting account will be created is called RAID-Z. What's different about it is that at least one of the disks is employed as a parity drive. In simple terms, whenever any data is duplicated on this specific hard drive, one more bit is added to it and in case a faulty disk is changed, the info that will be duplicated on it is a mix of the data on the other drives in the RAID and that on the parity one. It's done this way to ensure that your info is intact. Throughout this process, your Internet sites will be functioning normally as RAID-Z makes it possible for a whole drive to fail without service disturbances and it simply works by using one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to guarantee that no data shall get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
