Using RAM: speeds is not a good metric for measuring AmigaDOS throughput. RAM: implements it's own handler - l:Ram-Handler and does not use a normal AmigaDOS filesystem. A physical disk device or Recoverable Ram Disk like ASDG's uses a normal AmigaDOS file handler which provides only 35K/Sec maximum throughput, and you had better use it on a disk if you want to be 100% compatible...
