Three-terabyte desktop storage
The Buffalo Technology OP-HD3.0QH is a 3.5 inch internal hard drive with a 3TB capacity and a SATA 3.0Gb/s interface. It fits standard desktop drive bays measuring up to 1.18 inches high, 4.13 inches wide and 6.70 inches long. This drive suits users adding bulk storage to a workstation or home server.
Sustained write behaviour
The SATA 3.0Gb/s link sets the ceiling for continuous data transfer during long copy or backup jobs. Mechanical throughput will vary with file size and fragmentation but remains consistent across the full 3TB span. The drive handles sequential workloads such as media archiving or disk imaging without the thermal throttling seen in smaller form factors.
Thermals and power in use
A 3.5 inch mechanism running at 30 mm height dissipates heat through the metal chassis into the case airflow. Acoustic output stays at typical desktop levels during idle and seek operations. Power draw follows the SATA specification for 3.5 inch devices, requiring only the standard 12 V and 5 V rails from the system supply.

Questions about this item
How much power and heat does the 3TB SATA 3.0Gb/s drive produce when running continuously?
The 3.5" drive fits standard desktop bays at 1.18" high, 4.13" wide and 6.70" long, drawing typical SATA power levels for a 3TB mechanical disk.
What motherboard connector and bay size are required to install this 3.5" SATA drive?
A free SATA 3.0Gb/s port and a 3.5" drive bay measuring at least 1.18" high, 4.13" wide and 6.70" deep are needed.
Will this SATA 3.0Gb/s drive work in a system that only has SATA 1.5Gb/s ports?
Yes, the SATA 3.0Gb/s interface is backward compatible with older 1.5Gb/s ports, operating at the slower speed.
