Description
Product Specifications
The 0B27974 Hitachi Ultrastar is a hard drive designed by Hitachi Global Storage Technologies. It is a 600GB hard drive with a 10,000 revolutions per minute (RPM) spindle speed, a Serial Attached SCSI (SAS) interface with 12GB/s data transfer rate, and a 128MB cache buffer. This hard drive was designed for enterprise-level applications, where high performance and reliability are crucial. In this article, we will take a closer look at the features of the 0B27974 Hitachi Ultrastar hard drive.
Capacity and Spindle Speed
The 0B27974 Hitachi Ultrastar has a storage capacity of 600GB, which is suitable for storing large amounts of data such as documents, photos, videos, and applications. The spindle speed of this hard drive is 10,000 RPM, which is considered a high-speed hard drive. A higher spindle speed means faster data access and transfer rates. This makes the 0B27974 Hitachi Ultrastar ideal for applications that require fast access to data, such as databases, file servers, and online transaction processing (OLTP) systems.
Interface and Data Transfer Rate
The 0B27974 Hitachi Ultrastar hard drive has a Serial Attached SCSI (SAS) interface. SAS is a point-to-point interface that provides high-speed data transfer rates and is commonly used in enterprise-level applications. This interface allows the hard drive to communicate with the server or storage system, providing fast data transfer and improved performance. The data transfer rate of the 0B27974 Hitachi Ultrastar is 12GB/s, which is considered a high-speed data transfer rate. This high data transfer rate makes it an ideal choice for applications that require fast data transfer, such as video editing and streaming, and data backup and recovery.
Cache Buffer
The 0B27974 Hitachi Ultrastar has a 128MB cache buffer. The cache buffer is a small amount of high-speed memory that acts as a temporary storage area for frequently accessed data. The cache buffer improves the performance of the hard drive by allowing it to access frequently accessed data quickly. This results in faster data access and transfer rates, especially for applications that involve random data access such as databases, file servers, and OLTP systems.
Reliability and Durability
The 0B27974 Hitachi Ultrastar is designed for enterprise-level applications, where high reliability and durability are essential. This hard drive is designed to handle the heavy workload of enterprise-level applications, which involves continuous read and write operations. It has a Mean Time Between Failures (MTBF) of 2 million hours, which is a measure of the average time that a hard drive can run without failure. This high MTBF rating means that the 0B27974 Hitachi Ultrastar is a reliable hard drive that can operate for long periods without interruption.
In addition, the 0B27974 Hitachi Ultrastar has a Rotational Vibration Safeguard (RVS) technology, which reduces the effects of rotational vibration in multi-drive environments. This technology ensures that the hard drive operates smoothly even when it is installed in a server or storage system with multiple hard drives. The 0B27974 Hitachi Ultrastar is also designed to handle high temperatures, which is essential for enterprise-level applications that involve continuous operation.
Compatibility
The 0B27974 Hitachi Ultrastar is compatible with a wide range of server and storage systems. It is designed to work with SAS controllers that support SAS 12Gb/s data transfer rates. This hard drive is also compatible with SAS expanders, which allows for the connection of multiple hard drives to a single SAS controller.
