Average lifespan
The NAS enclosure itself can last a decade. However, the hard drives inside are consumable and typically need replacing every few years depending on workload.
Error: Volume Degraded
One of the drives in the RAID array has failed or disconnected. The data is still accessible but is at high risk; replace the faulty drive immediately.
Error: I/O Error
The NAS encountered read or write errors on a specific disk. This is a strong early indicator that the disk's mechanical parts are failing.

Common Failure Modes
Hard drive failure is the most common issue, which is why NAS uses RAID redundancy to prevent data loss. Fan failures and power brick deaths are the primary hardware issues for the enclosure itself.
