Seagate Cheetah x15 question

[MadHatter]

I noticed in seagate's harddrive listing, they have two model numbers for the Seagate Cheetah x15 18GB Ultra160 SCSI drive. I'm wonder what is the difference between the two? Here are the model numbers:

ST318451LC (the one reviewed today here on Tom's hardware)
ST318451LW

I looked at the specs and price, everything looks identical. Could someone help me out? Seagate also has the same pattern with the rest of it's drives listed. One will end with LC and another with LW. But for the life of me, I can not find any information as to what these appending characters refer to.

One is SCA-2 (single 80-pin interface), and the other is 68-pin. The two are of identical capacity and speed.

SCA-2 is specifically for hot-swappable drives and requires special hardware to connect (i.e. external RAID cabinet, or a chassis with an SCA backplane, or a $30+ converter board). This is probably not what you want; the 68-pin interface is more commonly used and less expensive to support.
