Product Specifications to the 0B23318 Hitachi Ultrastar 15K450
The 0B23318 Hitachi Ultrastar 15K450 is a high-performance hard disk drive designed for enterprise-level servers and storage systems. It is manufactured by Hitachi Global Storage Technologies, a subsidiary of Western Digital Corporation.
In this article, we will explore the features and specifications of the 0B23318 Hitachi Ultrastar 15K450 in detail.
Design and Physical Characteristics
The 0B23318 Hitachi Ultrastar 15K450 has a form factor of 3.5 inches and is designed to fit into standard drive bays. It has a storage capacity of 300GB and operates at a rotational speed of 15,000 revolutions per minute (RPM). This high-speed operation makes it suitable for data-intensive applications that require fast access to data.
The drive also features a 16MB buffer and supports the Serial Attached SCSI (SAS) interface, which has a data transfer rate of 3 gigabits per second (Gbps). This interface is commonly used in enterprise-level servers and storage systems because of its high performance and reliability.
Performance and Reliability
The 0B23318 Hitachi Ultrastar 15K450 is designed for high-performance applications that require fast data access and transfer rates. Its 15,000 RPM rotational speed enables it to deliver fast read and write speeds, making it suitable for use in applications such as online transaction processing, data warehousing, and scientific computing.
The drive also features a 16MB buffer, which helps to improve performance by temporarily storing frequently accessed data. This buffer acts as a high-speed cache that can be accessed quickly, reducing the time required to access data from the drive.
In addition to its performance, the 0B23318 Hitachi Ultrastar 15K450 is also designed for high reliability. It features a Mean Time Between Failures (MTBF) rating of 1.6 million hours, which is a measure of the average time the drive is expected to operate before it experiences a failure. This high MTBF rating makes it suitable for use in enterprise-level environments where reliability is critical.
Advanced Features
The 0B23318 Hitachi Ultrastar 15K450 also includes several advanced features that enhance its performance and reliability. These features include:
- Advanced Power Management: The drive features advanced power management capabilities that help to reduce power consumption and heat generation. This feature helps to extend the life of the drive and reduces the overall cost of ownership.
- Thermal Fly-height Control (TFC): TFC technology helps to maintain the distance between the drive head and the disk surface, even in high-temperature environments. This feature helps to improve the reliability of the drive by reducing the risk of head crashes and other mechanical failures.
- Rotational Vibration Safeguard (RVS): RVS technology helps to mitigate the effects of rotational vibration that can occur in multi-drive environments. This feature helps to improve performance and reduce the risk of data loss or corruption.
Compatibility
The 0B23318 Hitachi Ultrastar 15K450 is compatible with a wide range of operating systems and storage systems. It supports the SAS interface, which is widely used in enterprise-level servers and storage systems. It also supports hot-swapping, which allows the drive to be replaced without shutting down the system.
In Summary, the 0B23318 Hitachi Ultrastar 15K450 is a high-performance hard disk drive that is designed for enterprise-level servers and storage systems. It features a storage capacity of 300GB, a rotational speed of 15,000 RPM, and a 16MB buffer. It also includes several advanced features that enhance its performance and reliability
