IBM 25L2496 6.4GB IDE Ultra ATA/33 (ATA-4) 4200 2.5-inch 420KB Hard Drive

Product Description

The IBM 25L2496 is a compact 6.4GB internal hard drive, presented in a 2.5-inch form factor, which was standard for many portable computers and smaller devices during its era. It utilizes the IDE (Integrated Drive Electronics) interface, also known as ATA or PATA (Parallel ATA), specifically adhering to the Ultra ATA/33 (ATA-4) specification. This interface provides a maximum theoretical transfer rate of 33.3 megabytes per second, suitable for the performance demands of older systems. With a rotational speed of 4200 RPM, this drive prioritizes lower power consumption and quieter operation, characteristics often sought after in notebook computers of the late 1990s and early 2000s. The drive is equipped with a 420KB cache buffer, which helps to improve data access times by storing frequently used data. While modest by today's standards, this cache was typical for drives of this capacity and interface type. This 6.4GB IDE hard drive is an ideal component for restoring or maintaining vintage laptops, embedded systems, or any application that requires an older PATA interface. Its limited capacity makes it suitable for basic operating systems and essential applications, and its low power draw ensures it won't unduly strain the battery life of portable devices. Compatibility is key, and this drive is designed to work with motherboards and controllers that support the ATA-4 standard.
