MacBook :: Shall I Fit A 7200rpm Hard Drive Into My Black

i bought high spec black macbook refurbished which came with a 5400rpm drive inside it.

Im using logic pro, and its been running fine with small projects, but when i have a medium sized project using several vst instruments and exs24s using many audio samples, all of which are running off the internal.... i get error messages, system overload messages...and i am unable to bounce to audio file (in logic pro)

im thinking its the slow hard drive which is causing the main problems.

I have 2gb ram. It also takes sometimes over 5 mins to open this logic file.

Or is this poor performance par for the course, if using just one internal drive, for both system files and audio storage....... ?

Are there possible probs which may arise from taking out the 5400 drive and fitting a faster 7200 drive in to my macbook? I hear it will heat up more....so could this mess with other macbook componets?? the excess heat...... or are macbooks bulit to handle 7200rpm drives too? dont remember is 7200 was an optional upgrade with my model or not......

2.4ghz intelcore2duo.

Anybody fitted a 7200 drive into their macbooks? all running ok??

Would i simply put the new hard drive in..... and then boot up from boot dvds and my time machine backup....to have a full up to date system, all apps and file intact as they are now? Im worried it will get messy and problems...... my current drive is packed to rafters with apps and files and work i have done......i dont want to lose a thing.....would it be a simple easy fool proof transition to faster hard drive?

And could i still use the current hard drive? With an enclosure?

Ive heard people have ripped out the opticla dvd drive and fitted ANOTHER hard drive into their macbooks, so the laptop housing two hard drives..... that sounds good...but crazy..... maybe later ill do that....as i hardly use the cd/dvd drive...... and you can always hook it up with wire if need be
