I've just bought a new notebook and it has Seagate Momentus ST1000LM024 HN-M101MBB HDD inside. Right now the problem is that HDD is the slowest part of my laptop and I thought of replacing it with Seagate Momentus ST9750420AS. My main point is 5400RPM -> 7200RPM. 250GB loss doesn't seem like a big problem.

Do you think this is a good idea? If so, how much would I have to pay (approx.) for such a switch? And maybe there are other HDDs, better than the one I suggested (WD Scorpio Black WD7500BPKT)?

For the most boost in performance go for an SSD, it's quick, but the storage capacity will take a hit. You'll probably get 120GB for the price of a 1TB HDD. –  Martin Jul 15 '13 at 12:20
If you can't suffer a storage decrease, nor spend much on an SSD, look into the new Seagate Hybrid drives. You'll spend around 90-130 if I recall correctly, but you'll get a fairly significant speed boost. –  nerdwaller Jul 15 '13 at 12:33

I would strongly advise you not to put a 7200rpm HDD in your laptop for three reasons:

  1. The first is that I am assuming what you mean by "slowest part of my computer" is your windows experience index. Disregard this number, it is only an index, a numerical representation that sums up your components so that you can compare two computers link. A laptop will generally have a lower WEI than a desktop. Since you have already bought this laptop that number really doesn't have any value anymore.

  2. The reason why laptops have a 5400rpm HDD is to prevent heating issues as well as give you greater battery life. The faster the RPM the more power consumed and by extension the more heat generated. I would strongly advise not to put a 7200RPM HDD into your laptop unless your willing to trade a minor speed performance issue for a major heating issue and poor battery life.

  3. You will miss those 250GB later

If you really want to boost your disk performance then I would advise you get an SSD. They are faster, smaller, and don't really produce much heat. The only drawback is they are pricier and have smaller capacities, but if you are willing to throw away 250GB then that shouldn't be an issue.

Buy a hybrid Seagate drive. I also had the same problem, replaced the HD with Seagate hybrid Momentus drive, and my laptop got really faster. I am not speaking about experience index or any bechmark but the speed difference is really noticable.

I would recommend an SSD drive, but 120 or 250 GB most of the time simply not enough.
