0F12455 Hitachi Ultrastar 7K3000 2TB 7.2K RPM SATA 6GBPS 64MB Buffer 25.4mm Internal Hard Drive | Refurbished

The 0F12455 Hitachi Ultrastar 7K3000 is a hard disk drive (HDD) designed for use in servers, storage arrays, and other enterprise-grade applications. In this article, we will explain the features and specifications of this HDD in detail.

Capacity and Performance

The 0F12455 Hitachi Ultrastar 7K3000 has a capacity of 2 terabytes (TB), which means it can store up to 2 trillion bytes of data. The drive spins at a speed of 7,200 revolutions per minute (RPM), which is faster than most consumer-grade HDDs. This high RPM allows the drive to read and write data faster, making it ideal for applications that require high data transfer rates.

Interface and Buffer

The 0F12455 Hitachi Ultrastar 7K3000 uses a Serial ATA (SATA) interface with a maximum data transfer rate of 6 gigabits per second (Gbps). The SATA interface is commonly used in computer systems and provides a reliable and easy-to-use interface for data transfer.

The drive also features a 64 megabyte (MB) buffer, which is used to temporarily store data that is being read from or written to the disk. The larger the buffer, the faster the drive can transfer data to and from the computer system.

Form Factor and Dimensions

The 0F12455 Hitachi Ultrastar 7K3000 is a 3.5-inch internal hard drive, which is the standard size for desktop and server HDDs. The drive has a height of 25.4 millimeters (mm) and is designed to fit into drive bays that support the 3.5-inch form factor.

Reliability and Durability

The 0F12455 Hitachi Ultrastar 7K3000 is designed to be a reliable and durable HDD for enterprise applications. The drive has a Mean Time Between Failures (MTBF) rating of 2 million hours, which means that the drive is expected to operate for an average of 2 million hours before failing.

In addition to the MTBF rating, the drive also features a number of technologies that help to improve its reliability and durability. These technologies include:

• Rotational Vibration Safeguard (RVS): RVS technology helps to minimize the effects of vibration on the drive. This is important in enterprise environments where multiple drives may be operating in close proximity to each other.
• Thermal Flyheight Control (TFC): TFC technology helps to maintain a consistent distance between the read/write head and the disk surface. This helps to prevent data loss due to head crashes, which can occur when the head comes into contact with the disk surface.
• Head Load/Unload: Head load/unload technology helps to prevent the head from coming into contact with the disk surface when the drive is not in use. This helps to prevent damage to the disk surface and extend the life of the drive.

In summary, the 0F12455 Hitachi Ultrastar 7K3000 is a high-performance, reliable, and durable HDD designed for use in enterprise applications. With a capacity of 2TB, a speed of 7,200 RPM, and a SATA interface with a maximum data transfer rate of 6Gbps, the drive is well-suited for applications that require high data transfer rates. The drive also features a 64MB buffer and a number of technologies that help to improve its reliability and durability, including RVS, TFC, and head load/unload.
