Staggered scrubbing

Staggered scrubbing is a scan-order strategy that visits segments across multiple disk regions before returning to subsequent segments in each region.

It aims to locate clustered damage earlier and then inspect the affected region; it is distinct from merely increasing scan frequency.

Limitations

• Historical HDD scan-order results are not guarantees for SSDs or array data-loss rates. [1]
