Why no 100GB for the 15 incher?

Hopefully this hasn't been posted yet, I searched and found nothing, but I'm not that good at observation.

I recently decided to buy a 15inch C2D MBP instead of the 17-inch one, but online I find the hard drive options lacking. Why can't I get a faster drive with lower capacity because of the screen size I favor? Plus, its a cheaper option, and I barely use up a 40 GB harddrive, so space is not an issue.

So again, why no 100GB (7200rpm) for the 15" Macbook Pro?

Heat issues would be my first guess.

i think the 160gb and the 200gb option are actually just as fast or even faster. rpm's aren't the only factor that come into play with actual read and write times. Also the 160gb, 200gb, and 120gb all have the new pmr technology(Perpendicular Magnetic Recording) which is much faster than the lmr technology used in the 100gb.

If the 5400rpm disks are faster than the 7200rpm one, why is it an option on the 17" MBP? That don't make sense to me!

Not true. Tom's hardware benchmarked the new 5K160 (160GB Perpendicular) and the 7K100 (7200RPM 100GB Drive) still beats it steadily in every test. The 5400RPM PMR is fast but not nearly as fast as a 7200RPM.

As to why Apple didn't make this an option on the 15 is anyone's guess. It was an option on the last MBP and worked well.

Yes, several sites have also showed the same (7200rpm beating 5400rpm PRM drives)
