Seagate BarraCuda ES.2 500GB 7200RPM SAS 3Gb/s 16MB Cache 3.5" Enterprise Class Hard Drive - ST3500620SS

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. Seagate PowerTrim technology dynamically optimizes power consumption by improving GB/watt by 55 percent over prior generation of Barracuda ES drives. Full internal IOEDC/IOECC data integrity protection on SAS models. Dual ported, multi initiator SAS provides full duplex compatibility and a 135 percent average performance improvement over SATA.
