Overview

• 2.5-inch Enterprise Hard Disk Drives offer 10K RPM spindle speed and feature storage capacities up to 147GB⁽¹⁾
• More performance per U — up to 24 2.5-inch HDDs in a 2U system
• Mean-time-between-failure (MTBF) of 1,400,000 power-on hours
• Best in Class power consumption at idle vs. competitive 2.5-inch 10K SAS HDDs
• Ideal for mission critical server and storage system applications

Features

Enabling point-to-point connections, Fujitsu SAS hard disk drives help enterprises develop new solutions and maintain flexibility. These 2.5-inch HDDs offer up to 147GB of storage and 10K RPM spindle speed — ideal for high-end, missioncritical applications residing on database servers, storage arrays, and NAS and SAN systems.

Seventy percent smaller than conventional 3.5-inch enterprise drives, a greater number of 2.5-inch SAS drives can be installed in the same space, resulting in improved input-output (I/O) performance. Additionally, lower power consumption per drive and smaller form factor reduces system cooling requirements.

The 3Gb/sec SAS interface improves system performance while dramatically reducing the cabling footprint, resulting in better system heat dissipation
