Description
Product Specifications
The 0B23491 Hitachi Ultrastar 450GB 15K RPM SAS 3GBPS 16MB Hard Drive is a high-performance hard drive designed for enterprise use. It has a capacity of 450GB and a spindle speed of 15,000 revolutions per minute (RPM). It connects via a Serial Attached SCSI (SAS) interface with a data transfer rate of 3Gbps, making it suitable for demanding applications that require fast data access.
Capacity
The 0B23491 Hitachi Ultrastar hard drive has a capacity of 450GB. This means it can store up to 450 billion bytes of data, which is equivalent to approximately 450,000 high-resolution photos or 100,000 songs. For enterprise applications that require large amounts of storage, this capacity is ideal.
Spindle Speed
The spindle speed of a hard drive refers to how fast the disk inside the drive spins. The faster the spindle speed, the faster the data can be accessed. The 0B23491 Hitachi Ultrastar hard drive has a spindle speed of 15,000 RPM, which is much faster than the typical consumer hard drive. This high spindle speed makes the Ultrastar hard drive ideal for applications that require fast access to large amounts of data, such as databases or video editing.
Interface
The 0B23491 Hitachi Ultrastar hard drive uses a Serial Attached SCSI (SAS) interface to connect to a computer or storage system. The SAS interface is a high-speed, point-to-point interface that allows for fast data transfer rates. The Ultrastar hard drive has a data transfer rate of 3Gbps, which is the maximum data transfer rate for SAS 3.0. This interface is commonly used in enterprise environments where reliability and performance are critical.
Cache Size
The cache size of a hard drive refers to the amount of memory on the drive that is used to temporarily store frequently accessed data. This cache can help speed up access times for frequently accessed data. The 0B23491 Hitachi Ultrastar hard drive has a 16MB cache size, which is relatively small compared to some other high-performance hard drives. However, the high spindle speed and SAS interface help to make up for the smaller cache size.
Reliability
The 0B23491 Hitachi Ultrastar hard drive is designed for enterprise use and is built to be reliable. It has a Mean Time Between Failure (MTBF) rating of 1.6 million hours, which means that the drive is expected to last for a long time under normal operating conditions. In addition, the drive has a 24/7 duty cycle rating, which means it is designed to operate continuously without downtime.
In Summary, the 0B23491 Hitachi Ultrastar 450GB 15K RPM SAS 3GBPS 16MB Hard Drive is a high-performance hard drive designed for enterprise use. It has a capacity of 450GB and a spindle speed of 15,000 RPM, making it ideal for applications that require fast access to large amounts of data. The SAS interface and 3Gbps data transfer rate help to ensure fast and reliable data transfer, while the 16MB cache size helps to improve access times for frequently accessed data. Overall, the Ultrastar hard drive is a reliable and high-performance storage solution for demanding enterprise applications.
