RAID 50 is one of the most misunderstood and misdiagnosed RAID levels — even by IT pros and recovery labs.

Nested by design, it combines RAID 5 parity with RAID 0 striping, meaning one broken stripe group can silently destroy the entire array — even if all drives look healthy.

Many of the most dangerous failures don’t involve bad drives at all. They involve:

  • Parity mismatches invisible to your RAID card
  • Misread metadata triggering false foreign configs
  • Logical corruption inside one RAID 5 set
  • Controller swaps that break continuity without warning

Your RAID card may say “Online” or “All Drives OK” — but that doesn’t mean your data is safe.

ADR’s RAID Inspector™, built on our IntelliCore Logic™ platform, goes far beyond drive health. It inspects parity integrity, layout alignment, and cross-stripe cohesion to pinpoint what’s really happening before permanent damage is done.

Before you import foreign configs…
Before you clear metadata…
Before you force a rebuild that erases your only shot…

You’re not just hiring a lab. You’re engaging a partner that:

  • Built its own forensic-grade RAID Inspector™
  • Diagnoses logic-layer corruption other tools can’t
  • Offers real-time triage, imaging-first protocols, and controller-agnostic recovery paths

RAID 50 is complex — but ADR has the experience to rebuild it.
