Will a HDD Upgrade for Laptop benefit

I am wondering if a HDD upgrade for my laptop be worth it? I currently have a

Acer Aspire 5920G

• Core2Duo T9300
• 4GB DDR2
• GeForce 8600M GT
• 320GB HDD (5400rpm)

will a upgrade to 7200rpm HDD benefit/be worth it? I need more storage so i am considering a 500GB 7200rpm. Or will I be better off with a 5400rpm 1?

I do know that if you upgrade to a SSD, you will definitely notice an improvement. I have one in my Toshiba laptop and the improvement is remarkable.

I did think of that, but my laptop as you can see is quite old if i get an SSD, other components may become the bottleneck? any ideas? from what i see from Speccy

Code:

Manufacturer    Western Digital
Form Factor    GB/2.5-inch
Business Unit/Brand    Mobile/WD Scorpio®
RPM/Buffer Size or Attribute    5400 RPM with 8 MB cache (Mobile)
Interface/Connector    SATA 3 Gb/s with 22-pin SATA connector (Mobile)
Interface    IDE
Capacity    313GB
Real size    320,072,933,376 bytes

I wonder if a SSD will be worth it? I guess my laptop should support SSD via SATA 3GB/s? will Seagate 2.5" XT (Hybrid SSD) be a good buy? its almost double a normal SATA HDD tho

but on 2nd thought, maybe I wont really make full use of it. I am not a hardcore gamer, not editing large videos/photos? + my main requirement is more HDD space

Faster Hard drive = More heat
Major problem in laptops, I would stick with the 5400 rpm but a larger one.
