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

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.

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.

  With breakthrough capacity enabled  

by perpendicular recording technology,  
Barracuda ES.2 drives ensure maximum  
cost-effectiveness for capacity-intensive 
storage applications.
