WD jumper settings question

Building a new system. Windows 7 64bit, Gigabyte X58 UD5 mobo. Just taking a look at the new drives I got today.


Four of them are going to be in a RAID 5 array. They are all WD1001FALS 1T HDD's (http://www.newegg.com/Product/Product.aspx?Item=N82E168...). The sticker on the drive says jumper pins 3/4 for PUIS and pins 5/6 for 3Gb/s. I can't find anything on the WD site to clarify this (http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std...). These are already 3Gb/s drives. My previous disks didn't need to be jumpered for that AFAIR. Anyway, PUIS sounds like it would be bad to do with a RAID array but I don't know. So that's my first question. I'm guessing I don't want to jumper pins 3/4. Second is I'm guessing I should not have to jumper pins 5/6 because the WD site makes it sound like that will downgrade them to 1.5Gb/s.


Two of the drives are going to be RAID 0. They are WD6402AAEX 640GB HDD's (http://www.newegg.com/Product/Product.aspx?Item=N82E168...). Same thing on the sticker on the drive but it says pins 5/6 limits to 3Gb/s. I do want that because I'm going to use them in 3Gb/s SATA ports and these are 6Gb/s drives. So that's fine. I knew I would have to do that. But I have the same question on these regarding PUIS as with the 4 drives mentioned above.


I've never been confused about jumper settings on drives before. This time it's not clear enough to me so I thought I'd ask around.  

Thanks,

Avian.
