I have a Wren IV hooked up to my EasyData AT clone via an NCR SCSI
adaptor and Core reported an average seek time of 13 msec! Obviously
an artifact of having 32 kbytes of buffer in the disk. 

I don't get nearly the transfer rate you do. Down around 200 Kbytes/sec.

Are you sure you can connect a Wren IV to the WD 7000? I thought all
Wren IVs were SCSI. Is the WD 7000 SCSI?
