Limitations & Realistic Expectations

Myth: "Instant 2x speed boost" → Reality: Gains are subtle (5-20%) but cumulative with regular use. Myth: "Fixes all slowdowns" → Reality: Targets fragmentation only—pair with disk defrag for broader results. Myth: "Run daily" → Reality: Quarterly suffices; overdoing it yields diminishing returns.
