The 5.25" drives were available in both colors. The earlier beige model was called UniDisk 5.25" and the later platinum variety the Apple 5.25" Drive. There are slight internal differences between the two models but both serve the same basic purpose when connected to the IIe.

The DuoDisk was a unit with two 5.25" drives next to each other. It was as wide as a IIe and was designed to sit between the IIe and a monitor.
