The BUFFALO HD-QH16TU3R5 is a 16TB DriveStation Quad external storage system equipped with four 4TB NAS-grade hard drives. The four-drive design supports multiple storage modes, including RAID 0, RAID 1, RAID 5, RAID 10, and JBOD, allowing the unit to be configured according to the required storage arrangement.
Four-Drive External Storage
The HD-QH16TU3R5 contains four internal SATA hard drives, with each drive providing 4TB of capacity for a total installed capacity of 16TB. Buffalo identifies the internal drives as NAS-grade HDDs and provides support for several RAID configurations as well as JBOD operation.
RAID and Storage Modes
The DriveStation Quad supports RAID 0, RAID 1, RAID 5, RAID 10, and JBOD. These modes provide different ways to organize the four internal drives for storage capacity, redundancy, or performance. The appropriate configuration depends on the intended storage requirements and how the connected system will be used.
USB 3.0 Connectivity
The HD-QH16TU3R5 connects to a host computer through USB and supports USB 3.0 as well as USB 2.0. The USB 3.0 interface provides a maximum specified transfer rate of 5Gbps, while USB 2.0 compatibility allows connection to systems equipped with the older interface.
Key Features
- 16TB total capacity using four 4TB NAS-grade hard drives
- RAID 0, RAID 1, RAID 5, RAID 10, and JBOD storage modes
- USB 3.0 / USB 2.0 connectivity with one USB Type-A port
- Four internal SATA 3Gbps hard drives
- Desktop external storage system with AC power supply
Typical Applications
- High-capacity desktop file storage
- Centralized external storage for workstations and office systems
- Backup storage where a multi-drive configuration is required
- RAID-based storage for supported professional and business workflows
DC Supplies Product Note
The HD-QH16TU3R5 is configured with four 4TB drives rather than a single 16TB hard disk. This matters when selecting the unit for RAID because the four-drive architecture enables RAID 5 and RAID 10 in addition to RAID 0, RAID 1, and JBOD.
