HDD Question

[starnox]

I am looking into getting these:

http://www.swann.eu.com/stores/product_family_view.do?pubID=1669&familyID=48971

http://www.wdc.com/en/products/Products.asp?DriveID=38

Will these actually work together, the enclosure just says IDE ATA, not sure if the UlTRA ATA/100 will work with it.

Any recommendation or comments?
