I've a HD from CMI (Computer Memories Inc) with the name CMI 6640 ( 6 heads,
640 tracks, 35ms acess) but i don't know about the buffred seek time on it.
 
My controllercard is a old Xebec with following step options: 
Non buffring Seek - 3.0 ms (old ST506)
Buffred Seek - 200 us  (ST412)
                70 us
                30 us
                15 us
                12 us
 
My question:
 
Can CMI 6640 handle 12us buffred seek or must i use a higher value?
