well, actually, the 750gb/1tb samsung spinpoints F1's have been praised for incredible performance. I read a review in which the only hdd better than the spinpoint is actually a 150gb raptor, but in some benchmarks it beat it, like in transferrate. Here's the link:

It is in dutch though, so I'll just tell you what the benchies are for, in the order that they are in the review:sequential transferrate, start; sequential transferrate, end; average read service time; the last four don't need translating. The review and benchmarks are done by somebody who has a homeserver.
Just thought of the fact that it's a 100 euros, 77 pounds at the store you're looking at, so I dunno if you'd want that. If your choice is between the two you'd mentioned, I'd go for the 7200rpm. It's faster, and bigger. But the samsung is just a little more than twice the price, but a lot more storage, so maybe you should look into it.
