500Gb 7200 with 16 or 32Mb

[bcburrows]

Just wondering if anyone actually had figures for this. I have searched the topics here before posting but did not find what I was after.

Essentially I will be upgrading my 320Gb 5400rpm HDD to either a samsung or WD 7200rpm drive

Now my question is this - do I go for the 16mb or 32mb cache. I know the 32mb will be better - but what is the actual performance difference as the price difference is quite noticeable - £60 or $100 depending where in the world you are from.

Thanks for any help re numbers / personal experience

I know with desktop drives 16 vs. 32 yields little if any noticeable difference.

I must be out of the loop on laptop HDs...

Where do they offer a 7200rpm 2.5" drive with 32mb cache?
