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 single-
or dual-ported configurations and provides
