Quantum TM21A46202D 2.1GB ULTRA DMA 128KB Cache 3.5-Inch Hard Drive

Product Description

The Quantum TM21A46202D hard drive represents an advancement in IDE storage technology, offering a capacity of 2.1GB. It incorporates Ultra DMA (Direct Memory Access) support, which significantly improves data transfer rates over earlier ATA standards by allowing the drive to communicate more directly with the system's memory. This enhancement was crucial for improving the responsiveness of applications and the overall system performance. Equipped with a 128KB cache, this drive helps to buffer data and reduce latency, further contributing to its speed. The 3.5-inch form factor makes it a standard component for desktop computers, easily fitting into the drive bays of most PC cases. This combination of Ultra DMA and a cache buffer positions the TM21A46202D as a capable storage solution for its time, particularly for users who valued faster storage performance. Quantum, a known manufacturer of storage devices, produced this drive to meet the evolving demands for speed and capacity in personal computing. The Ultra DMA interface, often referred to as ATA-33 or ATA-66 depending on the specific implementation, provided a substantial performance uplift, making it a popular choice for systems that needed more than basic storage capabilities. This drive is a good example of the technological progress in hard drive interfaces during the late 1990s and early 2000s.
