RAID stands for redundant array of inexpensive drives. RAIDs can be configured for a few reasons, which are speed, making an exact duplicate of data, and for protective storage. In this video, Kevin Ames discusses what RAID 5 is and why you may want to use this type of RAID to store your digital files.
- The last type of RAID we're going to…discuss is RAID 5.…And RAID 5 is considered protected storage.…Because it stripes the data across five drives.…Kind of like RAID 0,…except it creates what's known as a parity drive.…I'll show you what that means with…this set of graphics.…Here we have the same five drives,…and as data is added to the drive,…it's broken down into blocks.…A one through four plus Ap.…
P stands for parity.…Then it does the B section,…the C, the D, and the E.…And you'll notice that across the five drives…there are also five parity partitions.…If any one of the drives fails,…what's going to happen is all of the data…on that drive is lost and you'll notice…that among the other four drives…all of the components,…A, B, C, D and E are available.…
The parity drives,…the parity partitions, rather,…make sure that the new drive that you put in…can be rebuilt and it may take some time…if you've got a 30 terabyte system.…It could take 48 to 64 hours…to rebuild and remap all of the data…to a new drive.…And nothing gets lost.…
