Seagate ST3750330NS Barracuda ES.2 Product Overview - Page 2

Barracuda® ES.2 The highest-capacity drives in Tier 2 nearline, business-critical storage Product Description 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 singleor dual-ported configurations and provides Specifications Capacity SATA 3Gb/s, 1.5Gb/s SAS 3Gb/s Spindle Speed (RPM) Cache, Multisegmented (MB) SATA 3Gb/s, 1.5Gb/s SAS 3Gb/s Seek Time, Read/Write (average, msec) Mean Time Between Failures (MTBF) (hours) Reliability Rating at Full 24x7 Operation (AFR) Transfer Rate, Sustained (MB/s) Power Consumption (W, idle) SATA 3Gb/s, 1.5Gb/s SAS 3Gb/s Rotational Vibration @ 1500 Hz max (rad/sec2) Limited Warranty (years) 1 TB, 750 GB, 500 GB, 250 GB 1 TB, 750 GB, 500 GB 7200 32 16 8.5/9.5 1.2 million 0.73% 105 (SATA), 116 (SAS) 8.0 10.2 12.5 5 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* power boost over SATA drives and superior data integrity with full IOECC/IOEDC.
