And... 7200 rpm vs other slower speeds.

BEWARE of false claims like the Green IntelliPower fraud by Westen Digital: all those drives are slower 5400 rpm in reality!!! They just use the word IntelliPower to avoid disclosing the real 5400 speed. Do not be fooled.

Since we are on the topic of external hard drives, would someone please tell me what happened to Moore's Law when it applies to storage these days? Storage devices have stopped doubling in capacity at the same rate that have in the past. We have basically been stuck at the 500GB 1TB level for the last three years or more!! Those of us that use video need 10 TB or more on a yearly basis. Where are the 100TB drives that we should have by now??? I am guessing that the video user market is not big enough and everyone is happy with their puny 500GB hard drives, but this really is screwing up things for the video hobbyists.

Weeeellllll.... Moore's Law isn't so much a "law", as it is a speculation based upon one man's fairly astute observations of technology trends during his lifetime. It's perfectly reasonable to expect speculations to be incorrect now and then, or to expect trends to be inconsistent and subject to lulls and sudden leaps.

On the other hand, I don't think that Moore ever stated that his observations extended to hard drive density; I think that's based upon inferences made by other observers. Moore only referred to transistor density on an integrated circuit board. So one could also readily argue that your storage issue has absolutely nothing to do with Moore's Law.

Ah-ha! Here we go: You didn't want to complain about Moore's Law... you wanted to complain about Kryder's Law.
