Speedcheck

This article provides information about the real measured speeds of the CPC's hardware using different software. The abbreviaton "n.f." means "not feasible", since some software is not capable of performing a particular task. Numbers in bold indicate the smallest needed time. All experiments have been repeated 10 times, the statistic means is given.

On CPC emulators the times can vary, for this tests only real CPCs has been used. For this tests the Dobbertin HD20 hard disc has been used.

Disc management

Various measurements of the floppy disc speed had been taken.

Format a disc: 40 tracks (Data) or 80 tracks (Vortex or 720K Dos)

Format	FutureOS	XD-DOS	Disc'o'Magic	CP/M 2.2	CP/M 3.1	Utopia	Windows 2000
Data	16	17	18	33	33	43	n.f.
Vortex	64	65	n.f.	65	n.f.	n.f.	104

Copy a disc: 40 / 80 tracks, one or two drives
