In the world of technology, certain products are quickly forgotten and replaced by newer, flashier models. But for Apple enthusiasts, the Macintosh Hard Disk 20 holds a special place in history as one of the company’s early innovations.
First introduced on September 17, 1985, the Macintosh Hard Disk 20 was designed, manufactured, and sold by Apple as part of its hard disk drive series. The external hard drive featured a 3.5″ Rodime hard disk, 20 MB of storage, DB-19 connection ports, and support for the Macintosh 512K. At the time of its release, the Macintosh Hard Disk 20 was priced at $1,495.
However, the Macintosh Hard Disk 20’s time in the spotlight was short-lived. The drive was discontinued on September 1, 1987. Today, the Macintosh Hard Disk 20 is 37 years old, but for those who were around to use it in its prime, it remains a nostalgic reminder of the early days of Apple and the evolution of technology.
While the Macintosh Hard Disk 20 may seem like a relic from a bygone era, it was a significant step in Apple’s journey to becoming the tech giant it is today. The drive’s impressive 20 MB of storage was a game-changer for Macintosh users at the time, and it paved the way for future innovations in storage technology.
Overall, the Macintosh Hard Disk 20 may be long gone, but it will always hold a special place in the hearts of Apple fans and technology enthusiasts alike.
