Power Consumption, Conclusion, Pricing, and Final Thoughts

Power consumption figures look good, and turn into impressive once capacity is taken into account. Realize that the BarraCuda Pro is not a NAS drive, so the second chart is not as relevant as it is for NAS builds, but it does suggest that Seagate's other NAS drives built on the same Helium-filled platform should be similarly impressive.



  • Excellent sequential performance.
  • Impressive 5-year warranty.
  • Good (low) power consumption.
  • Very quiet seeks , most of which were nearly inaudible *


  • * quiet seeks lead to moderate random / IOPS performance.
  • Price is a tad on the high side.

Pricing and Availability:

Seagate BarraCuda (current street price):

  • BarraCuda Pro 10TB: $509 ($0.051/GB) (Amazon)

WD competing units (street pricing):

  • Black 6TB $280 ($0.047/GB) (Amazon)
  • Red 8TB: $329 ($0.041/GB) (Amazon)
  • Red 6TB: $237 ($0.040/GB) (Amazon)

I've included some Reds here because while they are NAS drives, they can also be used for single drive applications. The BarraCuda pricing is good, but that extra 0.4 to 1.0 cent per GB adds up when you have 10,000 of them, pushing its price over the $500 point, which may be getting steep for some purchasers.


The Seagate BarraCuda Pro carries a 5-year warranty rated at 300TB/year written.

Final Thoughts:

Seagate's new BarraCuda Pro line offers impressive performance for their first foray into Helium-filled 3.5" drives. The high densities led to impressive sequential transfer performance, but random performance was a bit limited by longer seek times, pushing the 7200 RPM unit into 5400 RPM territory with our mixed workloads. Pricing (cost/GB) is competitive given the premium enthusiast capacity, but it remains a bit on the high side when contrasted with similarly performing units of lower capacity. Overall an excellent showing for Seagate's push into Helium-filled hard drives. Definitely worthy of the BarraCuda name!
