support question: Can You Explain RAID 5?
RAID 5 - raid 5 combines the features of RAID 0 and RAID 1. its basically spread the data across multiple disks and provides redundancy. RAID 5 does this by using parity bits, which can be used to regenerate data if one of the drives fails, but note that RAID 4 stores the parity bits on a single drive, whereas, RAID 5 stores the parity bits on all the drives. In either case, a set of X identical drives provides a capacity equal to X-1 Drives.
for example. lets say you have 6, 10G drives, the total usable disk space would be 100G,
formula : (6 x 20G) - (20G ) = 100G
as you can see if we multiply 6 drives times 6, we get 120G, so we subtract one drive 120G - 20G, we get 100G usable disk space
does that make sense?
