Seagate BarraCuda Pro 12TB HDD Review

Seagate's standard BarraCuda desktop hard drive range ends at 4TB, the BarraCuda Pro range however, goes way past this to the new flagship of the lineup, the leviathan 12TB drive. Although there are even bigger drives to be had in the enterprise segment, in the desktop space, the 12TB BarraCuda Pro is the largest hard drive available at the time of writing.

To get to its mammoth capacity the drive uses helium technology to allow eight 1.5 TB platters (discs) along with 16 reading/writing heads to be using in a standard, albeit 26.11mm thick enclosure.

Using helium (which is 1/7th the density of air) allows drive manufacturers to use thinner platters and be able to pack more of them into a drive chassis. This because using helium inside the drive reduces the drag force acting on the spinning disks as well as reducing flow forces acting around both disks and heads.

Seagate quote a sustained transfer rate for the 12TB BarraCuda Pro at 250MB/s, something we were able to confirm with the ATTO benchmark, the reviewed disk producing figures of 255MB/s for reads and 252MB/s for writes.

Official power ratings for the drive are active 7.8W, average idling 4.83W and 0.84W and 0.8W for Standby and Sleep modes respectively.

We found the 12TB BarraCuda Pro available to pre-order on Overclockers UK for £439.99 HERE

  • Huge capacity.
  • 5-year warranty.


  • Expensive

Kitguru says: The demand for cheap storage shows no sign of slowing down and Seagate's new 12TB BarraCuda Pro may not be that cheap at first glance for a standard hard drive but it is offering a huge amount of capacity in a single drive.
