Hard drives are your most vulnerable piece of equipment in your server, since they have moving parts and moving parts do wear out over time. That makes mirrored hard drives a big priority when choosing a redundant server make sure you look for this option when looking at dedicated hosting services. The easiest way to protect your server and your data from a hard drive failure is by mirroring the drive(s) so effectively one drive has the exact same information as the other and if one fails the other is still up and running. You can accomplish this in two ways using hardware RAID or a software RAID solution.
High end servers can have RAID systems with onboard cache memory that acts as a buffer for the hard drives. This cache normally has its own failsafe of an onboard battery backup just in case the power dies while the server is transferring data to the hard drives. That way when the power is back on the cache finishes writing the data and there is less chance of corrupted data.
