The 24TB NAS Drive That Makes a 4-Bay Synology a 72TB File Server

A 4-bay NAS with four 24TB drives in SHR (Synology 하이브리드 RAID) 배달하다 72 TB of usable capacity with one-drive fault tolerance. For a small business that has outgrown its 12TB NAS, that is a 6x capacity jump without changing the enclosure. The WD Red Pro 24TB is the highest-capacity drive in WD’s NAS lineup, combining 7,200 RPM CMR recording, 2.5 백만 시간 MTBF, 300 TB/년 작업량 등급, and AgileArray firmware optimized for multi-drive RAID environments. It is the drive you put in the NAS that now stores everything because the old NAS was too small.

Why 24TB — And the RAID 6 Question

At 24TB per drive, RAID rebuild time becomes a serious consideration. A single 24TB drive failure in a RAID 5 array triggers a 30+ hour rebuild. WD Red Pro includes TLER (Time-Limited Error Recovery), which caps drive-level error recovery at 7 seconds so the RAID controller can make the recovery decision instead of the drive hanging indefinitely. For arrays of 24TB drives, RAID 6/SHR-2 (이중 패리티) is strongly recommended — the probability of a second failure during a 30-hour rebuild is not negligible, and dual parity covers it. The 24TB Red Pro makes sense when you need capacity density per bay; for smaller deployments where rebuild time matters more than capacity, 8-16TB drives remain viable.
