Ever since I can remember, I've always insisted that my hard drives rotational speed is at least 7200 rpm. I find, without any technical or scientific basis, that 5400 rpm hard drives are, well, slow.
I'm talking for every day intense word processing, not even with photoshop or lightroom, as I've never had a hard drive slower than 7200 rpm when doing photo manipulation.
The last Dell I purchased I got the Caviar 10,000 rpm hard drives in a Raid 0 Array. They both burned out within a matter of weeks and when Dell replaced the entire tower (which arrived DOA), it had larger capacity drives but 7200.
So, if I haven't bored you yet, and even if I have, does anyone here have true experience or testing they can point to that the difference between 5400 and 7200, particularly in a notebook, will make a big difference, ALL OTHER THINGS EQUAL? Meaning same amount of ram, same processor speed, etc.
