The performance difference might be related to both the default sector size (512 bytes) and that I think synchronous transfers are disabled. I suppose there is a way to reformat the drive for 1024 byte sectors which might give some improvement. Does anyone know if indeed synchronous transfers are disabled when setting the jumpers in the recommended configuration, and why? I thought that the SCSI controller on the NeXT supports synchronous transfers. I'm interested because I would very much like to pick up one of these drives for my NeXTstation. louie
