I am looking at three WD HDDs from newegg. All three drives are in the $80 range. I will likely buy one and then add another later, potentially for a RAID0 setup. How much better for a RAID0 setup is the 2nd one listed below than the other two... I like the 250GBx2 better than the 160GBx2 in terms of mass storage, but exactly why are the 160GB HDDs supposed to be better for a RAID configuration? And what is the difference between the forst one and the third one, 8MB cache vs. 16? Thanks.
