Currenlty I'm in the progress of writing a plug-in for the total commander. Total commander is a nice piece of software for windows and it resembles the norton commander.
The plug-in allows the total commander to use the CBM4WIN drivers. It currently allows D64 and D71 image transfer from and to a commodore drive and it can format disks.
I can assure you these drives are not fast at all. During testing the image transferring the best I got was an avarage of ~2.3kB per second.
Remeber it is all relative. Compared to modern storage devices they are dog slow but compared to the good old datasette I think they do a good job.
