Does anyone know for sure that Turbodos delays writes to disk? It seems hard to believe that someone with enough knowledge to write Turbodos would make such a mistake. How much a delayed write cache would really buy on the ST is a good question. In a lot of cases it may not buy much over a write-through cache. The ideal disk caching program for the ST would: (1) provide a write-through cache, (2) be configurable to grab a user-specified amount of memory at boot time, (3) use a FIFO algorithm for allocating cache space, (4) allow the user to on-the-fly turn caching for any device on or off, and (5) interface to the rest of the system through the rwabs() vector. Such a capability should be a standard part of the ST system software (i.e. provided by Atari).
