Best-Fit Applications

  • Personal Attached Storage - USB/FireWire/eSATA
  • Small office and home data storage appliances
  • Low-power PCs

The brand new Seagate® Barracuda® LP (low-power) family is here, designed and built by the desktop performance leader, but with the primary focus on a low-power, cool and quiet drive at an entry-level price. This drive allows users to do more while using less power. The Barracuda LP drives deliver on low power consumption. But low power no longer means slow power. Benchmark performance results prove the 5900-RPM spin speed advantages (when compared to competitor drives that spin at 5400 RPMs). And these drives are cool and easy on the PC, often requiring fewer fans, a smaller power supply and lower maintenance costs. It’s the definition of energy efficiency.
