IBM DTTA-350320 3.24GB IDE/ATA 7200 3.5-inch 464KB Hard Drive

Product Description

The IBM DTTA-350320 hard drive is a legacy storage component designed for systems employing the IDE (Integrated Drive Electronics) or ATA (Advanced Technology Attachment) interface. With a capacity of 3.24GB, it was suitable for basic operating systems and applications in desktop computers and workstations of its era. The IDE/ATA interface, while superseded by SATA, was a prevalent standard for consumer-grade storage for many years, offering a straightforward connection method. This drive operates at a spindle speed of 7200 RPM, which was considered a performance-oriented speed for IDE drives, providing faster data access compared to 5400 RPM models. The 3.5-inch form factor is standard for desktop internal hard drives, ensuring physical compatibility with most computer cases. The 464KB of cache memory, though small by modern standards, helped to buffer data and improve read/write performance by reducing the need for the drive head to constantly seek data on the platters. IBM's DTTA-350320 represents a reliable option for users maintaining or restoring older computer systems that require an IDE/ATA hard drive. It is particularly useful for diagnostic purposes, data recovery from legacy systems, or for building period-correct vintage PCs. Its straightforward design and common interface make it a practical choice for specific retro computing needs.
