NAS or RAID Storage Array: storage thermal instability. The controller becomes unreliable or slows sharply when hot.

The distinguishing clue

Performance starts normally and falls or disconnects after sustained transfer.

Checks before an assessment

Record the storage system's alerts and which bays contain which drives. Do not initialise disks, change their order or begin a rebuild before assessing the array and backup state.

Stop point: Changing drive order or initialising disks can destroy recoverable array metadata.

Workshop confirmation and repair

Device-level check: Record drive order and array state, inspect each disk and preserve configuration before replacing anything.

Targeted check: Log temperature and transfer behaviour with adequate airflow. If confirmed: Correct cooling or replace the heat-sensitive drive after data is secured.

Repair boundary: Replace only the confirmed failed member and follow the correct rebuild or recovery process for that array.

Related cause to rule out

When the device hangs at detection or fails after sleep despite acceptable media health, also consider NAS or RAID Storage Array: drive firmware fault before choosing a repair.

Checks after the work

After repair or replacement, check share access, redundancy state, alerts, restart and backup verification.
