Your Synology NAS Has Been Running 24/7 for Four Years on Consumer Drives. One of Them Just Threw a SMART Error.
Consumer hard drives are not rated for NAS workloads. They do not include rotational vibration sensors. Their firmware is optimized for single-drive desktop use, not multi-drive RAID arrays. When a consumer drive in a 4-bay NAS starts failing, the RAID 5 rebuild on the remaining three drives pushes them to their workload limit — and the second failure that destroys the array is not a matter of if, but when. The Seagate IronWolf Pro 20TB is built for exactly this environment: 7,200 RPM, CMR recording, 300 TB/year workload rating, RV sensors, and AgileArray firmware that prioritizes RAID rebuild integrity over single-drive performance.
