With the addiction of interface 1, it is possible to connect a microdrive to the Spectrum. The interface 1 have the "controller" of the microdrives and the maximum number of microdrives connected is 8.
Each microdrive tape can hold up to 80K of data. The microdrive tapes consists of one loop of continuous band of magnetic tape.
If the data that the computer want have passed in the microdrive head, the microdrive must advance all tape to read again the data, this takes usually 8 seconds. It is not the best storage device but is more faster that tape.

The ZX Microdrives can me connected to the Sinclair QL, but the data storage format of ZX Spectrum cartridges are diferent of the Sinclair QL format.
