   The Apple-II cassette interface is simple,
   fast, and I think most reliable. The data
   transfer rate averages over 180 bytes per
   second, and the recording scheme is compatible
   with the interface used with the
   Apple- I.

Note that this is almost as fast as the floppy disk drive on the Commodore 64. This is why people remember Woz but not the anonymous engineer(s) behind the 1541 disk drive.

To be fair, the C64 slowness was due to a mistake:

Interesting! That's a great post. I knew they were using an IEEE-488 derived bus, but I wasn't aware of all the dirty laundry.

Woz's disk OS actually left a lot of low-hanging fruit on the tree as well, but at least the hardware wasn't burdened with so many legacy bottlenecks.

Wow, I used the 1541 for backups in one job. I never timed it, but I'm not surprised at your report.
