I'm taking this info directly off of a CDC glossy for the Wren 4...

CDC Wren 4 5.25" Rigid Disk Drive

Capacity			300MB formatted (1024-byte sectors)

Number of disks			5
Data surfaces			9
Servo surfaces			1
Tracks per surface		1365
Track Density			1280 TPI
Recording Density		19058 BPI
Recording Method		2.7RLL

Rotation speed			3600r/min
Average latency			8.3ms
Seek time			typical
	Single track		4ms
	Average			16.5ms
	Maximum			43ms

Interface type			SCSI
Transfer rate			Supports at one to one interleave
				1.50Mbytes/sec Async 3.0Mbytes/sec Sync.

So, it looks like it will only do SCSI. Let me know if you have any other
questions that the spec. sheets could answer.
