"This is our ten megabyte tribute to the great UltraSatan SD-adapter. Long live new Atari hardware! It should also work with normal harddrives if they can deliver about 500 kbyte/sec."
SatanDisk does not do that. My old ST harddrive from 1990 did over 1MB/sec, and the ~2006 SatanDisk didn't even go over 100 when I bought it, it was a huge letdown from being used to a really old harddisk and almost get back floppydisk speed again.. So I gave it away.
UltraSatan on the other hand corrects everything and is an excellent piece of hardware.
