An optional external 5 MB or, later, a 10 MB Apple ProFile hard drive (originally designed and produced for the Apple III by a third party), was available. With the introduction of the Lisa 2/10, an optional 10 MB compact internal proprietary hard disk manufactured by Apple, known as the "Widget", was also offered. As with the Twiggy, the Widget developed a reputation for reliability problems. The ProFile, by contrast, typically was long-lived. The Widget was incompatible with earlier Lisa models.
