Sorry, I think I misread your question. So, here what I think you want. The Seagate model number is very important to understand before making a purchase.
The suffix (last letters at the end of the model #) <b>ST318432<font color=blue>LW</font color=blue></b> of the HDD specifies the type interface, i.e., if you are building a Desktop Workstation in the LVD series, you would likely use the LW or LWV model. If a server with hot swapable HDD and RAID array you would likely want the LC or LCV model.
One is a 68 pin wide (not hot swapable), and the other is a 80 pin Single Connector Attachment (SCA) which is hot swapable.
Then after you decide which drive you will use, go to the link in <b>Labdog's</b> post above and determine the type SCSI controller you will need.
After viewing Labdog's link, I see that the Ultra320 Cheetah X15 comes in SCA only. Which means you will need a backplane to connect the HDD (usually for rack mount purpose). So, you are currently limited to the LW model, if yours is a workstation. See the SCSI Controller <A HREF="http://www.adaptec.com/worldwide/product/prodtechindex.html?cat=/Technology/SCSI&source=menu" target="_new">here</A>
Please study the <A HREF="http://www.seagate.com/support/kb/disc/discmodelinter.html" target="_new">information</A> on this page from Seagate's website. If you have questions post again. Hope this helps.
