The Supra & ICD drivers both handle RLL disks fine. The higher bit-rate from a RLL disk only affects the ST-506 -> Adaptec 4070 path, NOT the Adaptec 4070 -> AHDI path; that transfer rate remains the same. Remember that the Adaptec does local sector buffering. Regardless all the AHDI adaptors I've seen should be able to handle the full bandwidth of the ST DMA bus (10 megabits). dgc
