Seagate 1TB Barracuda ES_2

Last updated June 01, 2009 - Send Feedback

The Seagate 1TB Barracuda ES.2 is an enterprise-class drive, performing well singly or in a striped RAID. It was a solid performer in Photoshop tests, though not as fast as the Western Digital RE3. Six of these internal to my Mac Pro have provided flawless operation.

Like other Seagate models, partitioning and/or creating new volumes sometimes takes curiously long compared to Western Digital or Hitachi drives (easily 5X to 10X as long). This true on the Mac Pro and on the MacBook Pro (different hardware). However, once initialized it works without a hitch.

The ES.2 is very quiet, with head seeks barely audible.

CAUTION: see notes on Seagate drive failures (many models).
