Essential Terms

Data blocks are sliced up and spread evenly across multiple drives simultaneously. It dramatically boosts Data Transfer Rates because the OS can read from multiple drives concurrently, but it features zero redundancy. If a single drive in the array fails, the entire filesystem is permanently lost.

Every block of data written to Drive 1 is identically duplicated onto Drive 2. It offers exceptional fault tolerance and faster read speeds, but cuts your physical storage capacity exactly in half.

Data blocks are striped across a minimum of three drives, and mathematical checksum data (parity) is scattered across the disks. It provides a balanced middle-ground: it optimizes read performance and can survive the complete hardware death of any single drive in the array without losing data, while only sacrificing the capacity of one disk's worth of space. Current RAID 5 systems often have slow rebuild times and increased risk during rebuilds on very large disks.
