Data Sheet Barracuda ES.2 ® High-capacity, business-critical Tier 2 enterprise drives 1 TB, 750 GB, 500 GB and 250 GB • 7200 RPM • SATA 3Gb/s, SATA 1.5Gb/s and SAS 3Gb/s Key Advantages • 1-TB drive delivers 33 percent more capacity than the Barracuda ES drive. • The industry’s highest-reliability 7200-RPM drive, designed for 24x7 operation • Best-in-class rotational vibration tolerance ensures unrivalled performance in high spindle-density applications, and multi-drive firmware maximizes system availability. • Seagate® PowerTrim™ technology dynamically optimizes power consumption by improving GB/watt by 55 percent and by reducing overall drive power consumption by 20 percent over prior-generation Barracuda ES drives. • Choose SAS for the seamless Tier 2 enterprise experience, with improved data integrity and a 135 percent average performance boost over SATA. SAS also reduces integration complexity and optimizes system performance for rich media, reference data storage and enterprise backup applications. Best-Fit Applications • Storage-hungry business applications • Network attached storage (NAS) • Maximum-capacity servers • Rich media content storage—audio, video, image • Reference and compliance data storage • Enterprise backup and restore—D2D, virtual tape • Collaboration—email, messaging • Infrastructure—Web, print, file Barracuda® ES.2 High-capacity, business-critical Tier 2 enterprise drives Seagate Makes the Best Even Better With a 5-Year Limited Warranty • • • • Specifications 1-TB Seagate Barracuda ES.2 drive provides 33 percent more capacity than its predecessor. With a choice of either SATA or SAS interfaces, the Barracuda ES.2 drive utilizes perpendicular recording technology to deliver the industry’s highest-capacity 4-platter drive. SAS delivers up to a 38 percent IOPS/watt improvement over SATA. • • • • • 750 GB1 500 GB1 250 GB1 Model Number ST31000340NS ST31000640SS ST3750330NS ST3750630SS ST3500320NS ST3500620SS ST3250310NS Interface SATA 3Gb/s, 1.5Gb/s SATA 3Gb/s, 1.5Gb/s SATA 3Gb/s, 1.5Gb/s SATA 3Gb/s, 1.5Gb/s SAS 3Gb/s SAS 3Gb/s SAS 3Gb/s External Transfer Rate (Gb/s) 3.0 3.0 3.0 3.0 Transfer Rate Maximum Internal (Mb/s) Maximum Sustained, SATA (MB/s) Maximum Sustained, SAS (MB/s) 1287 105 116 1287 105 116 1287 105 116 1287 105 116 Cache, Multisegmented (MB) SATA SAS 32 16 32 16 32 16 32 — Performance Average Latency (msec) The best 7200-RPM reliability for 24x7 business-critical applications from a trusted source, backed by a 5-year limited warranty 4.16 4.16 4.16 4.16 Spindle Speed (RPM) 7200 7200 7200 7200 Seek Time Average Read/Write (msec) Track-to-Track Read/Write (msec) 8.5/9.5 0.8/1.0 8.5/9.5 0.8/1.0 8.5/9.5 0.8/1.0 8.5/9.5 0.8/1.0 Multi-drive firmware features and best-in-class rotational vibration (RV) tolerance maximizes system availability and performance in multi-drive systems.
