Your SCSI controller probably has a 68-pin connector. Your drive(s)
should be the same.

SCSI cables are available with the terminator attached. You probably
should read the SCSI FAQ:

I use only 10K RPM drives. The fans are noisier.

My Ultra 60 has 2 18 GB Seagate Cheetah drives bought from

http://www.serversupply.com/

They are showing ST39103LW (68-pin, 10K) drives at $87.00. SCA drives are
less expensive but you need a SCA backplane to use them.
