Is this hard drive a good one to replace my stock Hitachi 320 GB hard dive with in my 2011 i5 MacBook Pro? Is there going to be any difference inbetween the 5400 RPM Hitach drive and this 7200 RPM one?
Which Momentus?
I'd avoid the Momentus XT right now. That's the "hybrid" one with a flash cache in it where it intelligently stores frequently-accessed data. Great idea, but they're still struggling with making it work, and in my sore experience it turned out to be a battery hog that wouldn't hibernate reliably. I expected some hit from going to 7200rpm to go along with the faster performance, but the drop in battery life with that drive was ridiculous. Seagate has been releasing new firmware fairly often, but I'd wait until they get it right, based on my own experience with the drive (which I removed).
From what I've read, the Western Digital Scorpio Black and the Hitachi Travelstar seem to be the best-regarded 7200rpm drives right now. But Seagate has generally been well regarded. Except for the XT...

I missed the link in your post. Seems to be a non-XT drive. It'd probably be fine for you, but do check its power consumption specs and reviews versus the WD and Hitachi equivalents.
Put the OS install DVDin the SuperDrive, turn on while holding option, click to boot from the DVD, follow on screen instructions, enjoy.
No the Seagate 750GB isn't a very good drive. Check my review on Notebookreview or the one on Techreport.
The WD 750GB is definitely faster but also louder and consumes relatively a lot of power.
If you want 750GB I suggest to wait for Hitachi 7K750. It will probably come very soon. It will probably be nearly as fast as WD, while being quieter and consuming less power.
PS. I have the 500GB XT in my MBP and I like it a lot.
Don't you need to format the drive first?
I don't care that much about speed. It;s the size that matters most to me. As long as it's a little bit faster than 5400 RPM hard drives it's fine for me.![]()
