DriveStation Quad 24TB USB 3.0

The Buffalo DriveStation Quad HD-QH24TU3R5 is a desktop external hard drive that combines four 6TB drives into a single 24TB RAID array. It connects via USB 3.0 for broad compatibility with Windows and Mac computers. The enclosure includes NAS-optimised drives rated for continuous 24/7 operation. NovaBACKUP Buffalo Edition and Time Machine support provide automated backup options.

Suited for RAID capacity, not portability

This unit suits creative professionals and small offices needing a high-capacity external target with hardware RAID 5 or 10 redundancy and hot-swappable drive bays. It is not designed for mobile use due to its desktop form factor and AC power requirement. Buyers seeking bus-powered portability or a single-drive enclosure should consider other form factors. The legacy OS list may also limit appeal for modern-only environments.

Four-bay hardware RAID over USB 3.0

The defining specification is the four-bay hardware RAID controller that presents the four internal drives as one 24TB volume over a single USB 3.0 link. RAID 5 and 10 modes are selectable for capacity or redundancy, and drives can be swapped without powering down. This architecture decides whether the device matches a workflow that demands sustained throughput and drive-failure tolerance in an external chassis.

Questions about this item

How much heat or noise does the 24TB DriveStation Quad produce when it runs all day with its four 6TB drives?

The enclosure holds four high-performance NAS drives rated for continuous 24/7 operation, so it is built to handle sustained workloads without overheating or excessive fan noise.

What cables or host ports must I already have to connect this USB 3.0 desktop array?

A USB 3.0 port on a PC or Mac and the included USB 3.0 cable are all that is required; the AC adapter and power cord are also supplied in the box.

Will the RAID 5 or RAID 10 volume work with my older Windows 7 or Mac OS X 10.6 machine?

Yes — the drive supports Windows 7 (32-bit/64-bit) and Mac OS X 10.6, so the array can be recognised and used on those legacy systems.
