MK1214GAP specifications

The Toshiba MK1214GAP is a notable hard disk drive (HDD) that stands out for its balance of performance, capacity, and reliability. Launched in the early 2000s, it was primarily designed for use in portable devices such as laptops and external storage solutions. This drive is particularly recognized for its compact size and efficient power consumption, making it an ideal choice for mobile applications.

One of the key features of the MK1214GAP is its 120 GB storage capacity. While this may seem modest by today's standards, it was quite impressive during its time, as it allowed users to store a significant amount of data, including documents, media files, and software applications. The drive operates at a rotational speed of 5400 RPM, providing a good balance between speed and energy efficiency, which is particularly important for battery-operated devices.

In terms of technology, the MK1214GAP utilizes perpendicular magnetic recording (PMR), which enhances data density and improves read/write speeds. This technology enables the drive to pack more data into the same physical space compared to traditional longitudinal recording methods. Additionally, the drive features a 2 MB cache buffer, which helps improve performance by allowing faster access to frequently accessed data.

The Toshiba MK1214GAP is equipped with a SATA (Serial ATA) interface, which provides a high data transfer rate and greater bandwidth compared to older IDE interfaces. This allows for quicker data access and improved overall system performance. The drive’s form factor is 2.5 inches, making it compatible with a wide range of laptop and external storage configurations.

Reliability is another significant aspect of this HDD. It has built-in features such as advanced error correction and shock detection, which help protect the drive against data loss due to bumps and drops, a critical consideration for portable devices. Furthermore, Toshiba’s rigorous testing ensures that the MK1214GAP meets high standards for durability and longevity.

In summary, the Toshiba MK1214GAP hard disk drive combines a respectable 120 GB storage capacity with efficient performance and reliability. Its advanced technologies, including PMR and SATA interface, position it as a reliable choice for mobile computing, despite the advancements in storage technology since its release. Understanding these features helps users appreciate the MK1214GAP’s impact in the realm of portable storage solutions during its prime.
