750GB Serial ATA Drive @ 5400 rpm vs. 128GB Solid State Drive?

I'm getting a MacBook Pro; is the 128GB Solid state drive worth 90 dollars more than the 750GB Serial ATA Drive @5400 rpm if I have 8 GB memory? How would solid state improve my computer? Thanks!

SSD are all about performance. You will see a significant improvement using one.

In gaming computers, we tend to use SSDs for the c drive and TB(s) HDDs for the data storage drives.


SSD
- no mechanical parts. Quiet.
- lower power consumption then hard drives
- less heat generated
- typical data transfer rate 170 MB/s
- typical access rate 35 - 100 micro-seconds (fast)
- expensive


Hard drive
- mechanical parts. noise.
- more power requirements
- heat generated (due to moving parts)
- typical data transfer rate 80 MB/s
- typical access rate 5,000 - 10,0000 micro-seconds (slow)
- cheap
