One simple question -- I understand that access time is a device attribute consisting of the lateral movement time of the actuator and the rotation time it takes for the disk to spin under the head. Are there IDE disk drives out there with the types of access times associated with higher end SCSI drives?

Unfortunately for Adaptec I believe that your statement is substantially correct. Which leads me to a rather obvious question -- why is it that Adaptec hasn't made more of an effort to deliver a "high-end" server SCSI adapter and then to price that adapter at a high enough margin to attempt to compensate for the desktop market isssues you note? This used to be done (and probably still is) by the Unix vendors themselves as part of the deliverable -- you'd think that with NT this would be a good market for Adaptec. An example of a high-end server SCSI adapter could be a PCI-based quad SCSI adapter.

Does this mean that if data is being moved from one device to another on a SCSI system (e.g. from a SCSI CD-ROM to a SCSI HD) versus an Ultra DMA IDE system, the load on the CPU is the same?
