Rafa, Really, none, as best I can tell unless you have a system with the single drive which can be written to synchronously by the OS without interrupt. When the drive is operated synchoronously, data can only pass when the drive has signalled for it, thus, it won't be interrupted and can take the data stream at its maximum transfer rate. However, in the Amiga, it appears, based on what I found on my system, that the multi-tasking nature of the system is such that if the drive can take over the datat stream, then any other data transfer to that drive or other devices on the scsi buss must wait. I think it would be comparable to using synchronous transfer during backup to a tape drive where the tape gets to write the data, but the backup program will be locked out of reading data into a buffer during the tape writes. If the tape runs asynch, then while data is written to the tape, the backup program can read data from the hard drive. That's about the only analogy I can make that might explain the difference, Rafa.
