Ultrastar 7k4000 represents the sixth-generation HGST 5-platter design, which
has been field proven by top server and storage OEM and Internet giants.
Engineered for the highest quality, the ultra star 7k4000 is put through
grueling design tests during development and must pass stringent ongoing
reliability testing during manufacturing. Ultrastar 7k4000 delivers by
reducing downtime, eliminating Service calls and minimizing TCO. Operating at
7200 rpm, ultra star 7k4000 offers better overall performance than slower rpm
capacity-oriented drives, and does so at impressively low power-consumption
rates. The ultra star 7k4000 can help data centers achieve lower AC power and
havoc requirements. With five advanced power management modes, the 7k4000
achieves a 59% reduction in Watts during low rpm idle mode, and uses less than
1 w during standby/sleep modes, freeing up precious headroom for growing
Enterprise needs.
