0F10629 Hitachi Ultrastar A7K2000 2TB 7.2K RPM 32MB Buffer SATA-II 3.5Inch Enterprise Hard Disk Drive | Refurbished

The Hitachi Ultrastar A7K2000 is a hard disk drive designed for enterprise use. It is part of the Ultrastar line of HDDs produced by Hitachi Global Storage Technologies (HGST), a subsidiary of Western Digital. The specific model number for this drive is 0F10629. The Ultrastar A7K2000 is known for its high reliability, performance, and storage capacity. In this article, we will explore the technical specifications of this HDD in detail.

Storage Capacity

The 0F10629 Hitachi Ultrastar A7K2000 has a storage capacity of 2 terabytes (TB). This means that it can store up to 2 trillion bytes of data. For reference, 1 TB is equivalent to 1,000 gigabytes (GB) or 1,000,000 megabytes (MB). The storage capacity of the Ultrastar A7K2000 makes it suitable for enterprise-level applications that require a large amount of storage space, such as data centers and cloud storage services.

Rotational Speed

The rotational speed of a hard disk drive refers to how fast the disks inside the drive spin. The Hitachi Ultrastar A7K2000 has a rotational speed of 7,200 revolutions per minute (RPM). This is a relatively fast speed, and it allows the drive to access data quickly. A higher RPM typically translates to faster read and write speeds, which can improve overall performance.

Buffer Size

The buffer size, also known as the cache size, of a hard disk drive refers to the amount of memory the drive has available to temporarily store data. The Hitachi Ultrastar A7K2000 has a buffer size of 32 megabytes (MB). This means that the drive can temporarily store up to 32 MB of data before it needs to write it to the disk. A larger buffer size can help improve performance by reducing the number of times the drive needs to access the disk.

Interface

The 0F10629 Hitachi Ultrastar A7K2000 uses a Serial ATA II (SATA-II) interface. SATA-II is an older interface technology that was first introduced in 2004. It has a maximum data transfer rate of 3 gigabits per second (Gbps), which is slower than newer interface technologies such as SATA III and NVMe. However, the Ultrastar A7K2000 is still a popular choice for enterprise applications because it offers a good balance between performance and cost.

Form Factor

The form factor of a hard disk drive refers to its physical dimensions and shape. The Hitachi Ultrastar A7K2000 has a form factor of 3.5 inches. This is a standard size for enterprise-level hard disk drives, and it allows the drive to fit into most desktop computer cases and server racks. The drive is also relatively lightweight, weighing in at just 1.4 pounds.

Reliability

One of the key features of the Hitachi Ultrastar A7K2000 is its high reliability. The drive is designed to operate continuously in demanding enterprise environments, and it has a mean time between failures (MTBF) of 1.2 million hours. MTBF is a measure of how long a device is expected to operate before it fails. A higher MTBF indicates a more reliable device.

The Ultrastar A7K2000 also includes several features that help improve its reliability. For example, it has a Rotational Vibration Safeguard (RVS) technology, which helps protect the drive from vibration and shock. It also has a Bulk Data Encryption (BDE) option, which allows users to encrypt data on the drive to help protect it from unauthorized access.
