RAID 5 Storage Efficiency
Calculate usable disk space and overhead for a RAID 5 array based on individual drive capacity.
RAID 5 is widely used in enterprise storage for its balance of performance, redundancy, and capacity. This tool calculates the usable storage in a RAID 5 configuration, which follows the (n-1) rule, where 'n' is the number of drives. Understanding the parity overhead is crucial for infrastructure architects when provisioning storage for databases or file servers.
Calculating efficiency helps in budgeting for hardware acquisitions and ensuring that high-availability requirements are met without over-provisioning. By quantifying the 'cost' of redundancy in terms of lost storage bits, engineers can make informed decisions about whether to use RAID 5, RAID 6, or RAID 10 based on the specific needs of their application's I/O profile.

Terms: Calculations provide a theoretical maximum. Actual formatted capacity will vary based on file system overhead (NTFS, EXT4, ZFS) and sector sizing.
