QNAP HDD-SG5U84-24TB 24TB Spare Drive for Seagate Exos 5U84
Overview
The HDD-SG5U84-24TB is a genuine QNAP spare drive sourced for use with Seagate Exos 5U84 high-density enclosures. When a drive fails in a populated 5U84 chassis, replacing it with a matched spare keeps your rebuild I/O and capacity consistent across the array — mismatched drive models or capacities can complicate RAID rebuild times and tiering policies. This 24TB spare is the correct replacement unit to maintain a homogeneous drive population in a 5U84-based deployment.
Compatibility
Designed for use with the QNAP Seagate Exos 5U84 high-density NAS and storage enclosures. The 5U84 platform supports up to 84 large-form-factor drives in a 5U chassis — a common choice in surveillance video retention and high-capacity bulk storage deployments where drive uniformity across bays directly affects rebuild performance and storage pool predictability. Confirm your 5U84 enclosure firmware and drive compatibility list before installing; consult QNAP's official compatibility matrix for your specific enclosure revision to verify this drive is qualified for your unit.
Installation Notes
Install into any available 3.5-inch drive bay in the Seagate Exos 5U84 enclosure. The 5U84 supports hot-swap, so replacement can be performed without powering down the enclosure — verify your storage pool status and confirm the failed drive is correctly identified before removal to avoid pulling a healthy drive from a degraded array. After seating the replacement, initiate a RAID rebuild from the QNAP storage management interface and monitor rebuild progress to completion before returning the system to full production load.
