Hitachi Ultrastar 7K3000 3TB HDD 6GB/s 7200 RPM HUS723030ALS640 46W0531
The Hitachi Ultrastar 7K3000 3TB is the world’s first and only 7200 RPM hard drive rated at 2.0 million hours MTBF and backed by a five-year limited warranty. The Ultrastar 7K3000 represents the fifth-generation HGST 5-platter mechanical design, first introduced in 2004, and has been field proven by top server and storage OEMs as well as leading Internet giants. When the highest quality and reliability are a top requirement, customer field data proves that the Ultrastar 7K3000 delivers by reducing downtime, eliminating service calls and keeping TCO to a minimum.
Engineered for the highest reliability,the Ultrastar 7K3000 is not only put through grueling design tests during development but must also pass stringent ongoing reliability testing during manufacturing. Across the entire Ultrastar family, world-class quality control, combined with scientific root-cause analysis and multi-faceted corrective actions, ensure that HGST remains the recognized leader in quality and reliability for enterprise-class hard drives.
Increasing Capacity Density by 50%
Recent measures such as data de-duplication and thin provisioning have not been able to stem the explosive petabyte (PB) growth requirements in cloud storage and data centers. Pervasive Internet computing with remotely stored email, pictures and social media, all being accessed from light-weight tablet and notebook computers, is changing consumer expectations. Ongoing worldwide government data retention regulations and security requirements are also driving up data center and private cloud storage needs. At the same time,tile space and megawatts remain at a premium, while in some highly built-out metropolitan areas both are at an absolute “no-growth” state.
To meet these demands,the Ultrastar 7K3000 delivers 50% more capacity in the same footprint and does so at a 32% reduction in watts/GB versus our prior generation Ultrastar A7K2000 product. It is now possible to achieve a colossal 1.8 PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4U, 60-bay enclosures.
Offering Choices of Interface and Encryption
The HGST Ultrastar 7K3000 is the first HGST 7200 RPM drive available in both 6Gb/s SATA and 6Gb/s SAS interfaces and also available in two encryption options. The Ultrastar 7K3000 SATA model integrates easily with legacy SATA and Fibre Channel to SATA environments.
This Ultrastar 7K3000 SATA model is available with a bulk data encryption (BDE) option. The Ultrastar 7K3000 dual-port SAS model is targeted at emerging 6Gb/s SAS enterprise infrastructure and is available with industry standard TCG Enterprise_A encryption. When enabled, both of these hardware-based implementations encrypt all data on the drive using a private security key as it is written to the disk, and then decrypt it with the key as it is retrieved, giving users an extreme level of data protection.
These security options not only protect sensitive data but also reduce the time and effort involved in re-deploying hard drives since without the key,the data is unrecoverable.
Combining 7200 RPM Performance and Granular Power Control
Operating at 7200 RPM,the HGST Ultrastar 7K3000 offers better overall performance than slower RPM capacity-oriented drives, and does so at impressively low power consumption rates. When compared to HGST’s previous generation Ultrastar A7K2000,the 7K3000 is up to 3 times faster in sustained data transfer rates.
The Ultrastar 7K3000 can help data centers achieve lower AC power and HVAC requirements. With five Advanced Power Management modes,the Ultrastar 7K3000 achieves a 59% reduction in watts during low RPM idle mode, and uses less than 1W during standby/sleep modes,freeing up precious headroom for growing enterprise needs.
