I don't see what the IDE drives are in your link. It is generally true that newer drives are faster than older drives, and SATA drives are faster than IDE drives. I am positive that someone will be able to find exceptions to these rules, but for the most part they will hold.
Oh these IDE drives are almost 7 years old haha. I can't even remember where I got them from.
I kept researching and found out that most HD's will bottleneck at ~150MB/s transfer rates. IDE is 133MB/s so it's already somewhat slower.
I think this also means that SATA I/II/III doesn't make a difference in what I get.
So, I chose to buy a cheap SATA II drive on the New Years Sale for newegg
