Idle Read After Write (IRAW)

Idle Read After Write is a research technique that retains completed-write data for comparison with disk contents during idle periods.

The 2008 study evaluates cache and scheduling policies through traces and simulation. It does not certify present-day drives or quantify field failure prevention. [1]
