Brand: Hitachi
The Hitachi TRK-902 is a hard disk drive (HDD) that was introduced in 2000 by Hitachi Global Storage Technologies (now a part of Western Digital). It features a capacity of 21 GB (gigabytes), which was a significant increase from the previous generation of HDDs that had capacities of around 7-14 GB. The TRK-902 operates at a rotational speed of 7200 RPM (revolutions per minute) and uses a combination of magnetic forces and read-write heads to store and retrieve data on the spinning disk. The TRK-902's performance and reliability made it popular in desktop computers and external storage devices during the early 2000s. However, it has since been replaced by newer technologies such as solid-state drives (SSDs) and higher-capacity HDDs.
