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!
PROS:

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


CONS:

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