معرفی

HP / HGST Ultrastar 7K4000 HUS724020ALA640 (0F19462) 2TB 7200RPM 64MB Cache SATA 6.0Gb/s 3.5' Enterprise Hard Drive with a 2.0 million hours MTBF specification, originally offered with SATA 6Gb/s. Ultrastar 7K4000 represents the sixth-generation HGST 5-platter design, which has been field proven by top server and storage OEMs and Internet giants. Engineered for the highest quality, the Ultrastar 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. Doubling the capacity density As data center professionals across the globe work to meet growing enterprise needs, they face the dilemma of storing more data in the same footprint while also reducing power and HVAC consumption. The new Ultrastar 7K4000 provides twice the data storage capacity of the prior generation Ultrastar A7K3000 drive, and does so using fewer watts. Combining 7200 RPM performance and granular power control Operating at 7200 RPM, the Hitachi Ultrastar 7K4000 offers better overall performance than slower-RPM, capacity-oriented drives at impressively low power-consumption rates. When compared to the previous generation Ultrastar 7K3000, the 7K4000 offers up to a 155% improvement in sustained data transfer rate, and a 120% improvement in watts-per-GB. With five Advanced Power Management modes, a 36% reduction in watts during low-RPM idle mode, and using less than 1W during standby/sleep mode, the Ultrastar 7K4000 can help data centers achieve lower AC power and HVAC requirements, freeing up precious headroom
