Tool to Calculate Storage Efficiency
This tool allows an architect to design a RAID (redundant array of inexpensive disks) storage system. Given the total number of disks available and the level of RAID desired the designer is given the storage efficiency.
RAID Levels
RAID 1 -- Disk Mirroring
RAID 2 -- Bit Interleaved Redundancy
RAID 3 -- Bitwise Parity
RAID 4 -- Block Parity
RAID 5 -- Interleaved Parity Sectors
RAID 6 -- P+Q Redundancy
