That is to make the drives backward compatible with SATA-1 systems that doesn't have the recent BIOS to automatically throttle the drives down to the lower speed. I had that problem and I had to use the jumpers on the 200 and 250 SATA drives. I didn't need to use the jumpers on the two 360gb SATA drives I just installed because the controller is a more recent one than the other MB I was using. I think it's a good idea to have the jumpers set from the factory because before I knew of the jumpers, I thought I had a DOA drive because the computer (BIOS) didn't even know the drive exisited, until I set the jumpers, so maybe the HD maker(s) was getting a LOT of calls and/or returns because people thought the drive was dead, as I did. <shrug> I tend to think it's a hardware issue.
