Seagate BarraCuda Pro 12TB HDD Review

Our review sample drive came from Seagate without any retail packaging, just as a bare drive.


Although the BarraCuda Pro is built on a standard 3.5in format in terms of length and width, to accommodate 8 platters (discs) and 16 reading heads inside the enclosure it is some 26.11mm thick. Each disc has a capacity of 1.5TB (Areal density 923 Gb/in2 avg) rather than the 1.3TB disks that previous large capacity Seagate drives used.

Removing the PCB reveals a 256MB Samsung K4B2G164GF DDR3-1600 IC used for caching purposes and a motor controller branded Smooth 7800V5.

Try as we might we couldn’t remove the thermal pad on top of the drive controller without ruining it but if it’s the same as the one controlling the 10TB BarraCuda Pro then it’s an Avago TTB8100 IC.
