Quantum LD20A011-01-A 20GB IDE Ultra ATA/100 4500 3.5-inch Hard Drive

Product Description

The Quantum LD20A011-01-A is a hard disk drive designed for use in desktop computers and workstations that utilize the IDE (Integrated Drive Electronics) interface, specifically supporting the Ultra ATA/100 standard. This standard offered significantly improved data transfer rates over earlier IDE versions, making it a capable option for its generation. With a storage capacity of 20GB, it was sufficient for operating systems, applications, and user data in the early to mid-2000s. The drive features a 3.5-inch form factor, which is the standard size for desktop internal hard drives. Its rotational speed of 4500 RPM strikes a balance between performance and acoustics/power consumption, often making it a good choice for general-purpose computing where extreme speed was not the primary requirement. The Ultra ATA/100 interface allowed for theoretical maximum transfer rates of up to 100MB/s, a notable improvement for IDE technology. This drive is a representative example of the storage solutions prevalent before the widespread adoption of SATA interfaces and higher capacities. It would have been a common component in budget-friendly or mid-range PCs, providing reliable storage for everyday tasks. Its compatibility is limited to systems equipped with IDE controllers, making it a component for legacy system builds or repairs.
