I'm going through the same decision at the moment. I've posted a question over at the Apple discussion page.

I'll copy/paste it here in case I get any alternate answers. Also, the question i asked contained a list of suitable drives, which I believe represents the extent of the options at this time:
<snip start>
Yes, my 3 year old internal 80G Toshiba finally died recently (clicking noises, unmountable) somewhat spontaneously!
Looking at my options for a replacement, the decrease in production of 2.5" PATA drives means it's almost self-selection by default!
I'm looking for any feedback from users with real world experience of any of the drives below:
Western Digital:
160G

320G

Seagate:

On paper, there's nothing really to separate these drives. They all have pretty much the same transfer rates, weigh about the same, have similar shock/vibration ratings as well as a 3 year warranty.
What I'm really interested in (apart from general performance and perceived speed, which I assume will also be very similar) is *reliability*!! Oh, and how quiet and battery friendly these drives are.
I'll probably buy two (my other laptop is the same age and has the same original Toshiba HDD, so I think I'll make a preemptive strike on it!) and maybe even a spare, as it looks like the availability of 2.5" HDD is thinning and in the future, we may even be paying a premium for them being manufactured in small numbers
Also, assuming 100G was plenty of storage space, can anyone out there give me a good reason why I should seek out the now even rarer 100G 7200 drive in preference to any of the above? I keep reading that modern 5400 units offer similar performance to older 7200 units however, I'm still finding the odd article that contradicts that, indicating that the older 7200 units are still 'faster' overall, albeit not by that much.
Any comments based on real world experience and/or objective advice would be gratefully received.
<snip end>
Take a look at the responses I got there which, in summary were that there's nothing much to choose between all these drives and also, that there's no point in touching 7200 drives anymore, compared to modern 5400 units.
Anyone have any other comments on these drives?
Thanks.
