Help with purchase of laptop hard drive (replacement)

[Premi]

My laptop's harddrive had been acting funny lately, and the other day, I turned the laptop on and it said "Cannot find operating system" or something like that. I shut it down, tapped on the HDD, and it turned on again. Now i'm looking to replace the hard drive.

This is my laptop:
Sony VGN-NW150J

I preferably want 1tb, but 500-750gb would work. I currently have 500gb in it.
These are the ones I found (there may be better ones, but this is what I found to be the best. Suggestions would be nice!)

Which one is newer/better? Can you find me a better one?

maybe this. Get some extra RPMs in there for faster response time. http://www.newegg.com/Product/Product.aspx?Item=N82E16822236873

or larger size, but more expensive. http://www.newegg.com/Product/Product.aspx?Item=9SIA0AJ3438461

are you opposed to spending big bucks and going SSD?

I want to stay around $50-70. If I can get a decent SSD for less than $100, I'll buy it. Thanks for your suggestions by the way. And aren't WD blues more reliable and quitter than blacks? Also, from the two links, what are the differences between them besides the storage size? Which is better?
