The Synology HAS5310-12T is a 12 TB 3.5" SAS3 hard drive for NAS systems that run continuously. It supports multi-user environments and enterprise backup workloads. The drive has been validated for stable operation under heavy write workloads and continuous use. It can be deployed in shared storage setups and high-availability clusters to keep data accessible for critical business functions.
The SAS3 interface delivers high throughput when connected to compatible enterprise backplanes. Integrated performance monitoring lets administrators track drive health across the storage pool. The internal components are built for high-density multi-bay enclosures and RAID configurations. The drive is also mechanically stable in systems with significant rotational vibration.
Key Features:- 2.5 million-hour mean time between failures (MTBF) rating.
- 7.95 W typical operating power consumption.
- 3.5-inch enterprise form factor for server and NAS bays.
- Firmware updates via Synology DiskStation Manager.
- 690 g unit weight.
- Dimensions: 101.85 mm × 26.1 mm × 147 mm.
