Explanation

When performance is degraded but data is still accessible, a common cause is a RAID array operating in degraded mode - meaning one drive has failed and the array is rebuilding or reading parity on every access. RAID enclosures have status LEDs that immediately reveal a faulted or failed drive. This is a quick, non-invasive visual check that should be done first. Defragmenting (A) addresses a different problem and is premature. Asking users for a speed test (B) could help but doesn't diagnose the root cause. Rebuilding the array (D) is a remediation step that comes only after confirming there is actually a failed drive - you never start a rebuild without first verifying the problem.
