Seagate BarraCuda ES.2 Hard Drives
The Seagate Barracuda ES.2 drive uses second-generation Seagate perpendicular recording technology to provide up to one terabyte of storage in a single, 4-platter hard drive. This 7200-RPM drive with best-in-class reliability and rotational vibration tolerance was developed for 24x7 availability in high-density, Tier 2 storage applications. The drive’s integrated workload management feature aids in drive cooling during periods of prolonged activity. The integrated PowerTrim technology optimizes power consumption during operation and idle without any host interaction or performance loss. The Barracuda ES.2 drive comes with in-drive data integrity protection guaranteed through Seagate IOEDC/IOECC technology and is available with a choice of either SATA or SAS interfaces for convenient system initiators. SAS offers improved performance over SATA due in part to the dual processors, hardware sequential streaming, the 2.4 GHz SAS ASIC data rate and the SAS clock rate of 75 MHz.
The SAS interface allows Barracuda ES.2 drives to be freely attached to any SAS host in single- or dual-ported configurations and provides full-duplex support, with two active data channels, to as many as 16 concurrent initiators.
The Seagate Advantage
- 1-TB capacity and second-generation perpendicular recording technology provide 33 percent more storage than the previous highest-capacity nearline drive while substantially improving value in $/GB and GB/W.
- Highest-reliability 7200-RPM drive with best-in-class rotational vibration tolerance to maintain performance in densely packed, multi-drive system designs.
- Proprietary Seagate internal data protection features from a trusted source, backed by a 5-year limited warranty.
- Industry’s only nearline SAS drive provides 135 percent average performance boost over SATA drives and superior data integrity with full IOECC/IOEDC.
Enabling New Opportunities
- Seagate has applied its unparalleled enterprise technology and manufacturing expertise to deliver a 7200-RPM drive that meets the needs of 24x7, multi-drive, nearline applications.
- The Barracuda ES.2 drive now makes SAS available for seamless migration of aging Tier 1 transactional data to Tier 2 nearline storage.
