hesela.devRAID 0
RAID 0 stripes data across storage members without redundant copies or parity protection.
Layout: Consecutive chunks are assigned to different members in rotation. For N equal-sized active members contributing S bytes each, ideal data capacity is N x S before metadata and filesystem overhead. [1] [2]
Failure: Losing one member removes part of the array's logical data. The remaining members cannot reconstruct those missing chunks without another copy. RAID 0 is therefore distinct from parity RAID, which also uses striping. [1] [2]
Scope: Mixed-size Linux MD arrays can use multiple zones with fewer members in later stripes. The equal-sized formula is not a universal mapping rule for unequal devices. [2]
