Will 500 GB SSD Hybrid 2.5" HD decrease battery life?
I want to upgrade my MBP hard-drive (320 MB @ 5400 RPM; 4 GB RAM) as the original HD is flaking out (it's now painfully slow). I don't need a ton of HD space, so 500 GB is fine. Battery life is more important to me, as I'm on the road quite a bit.
I am considering installing the Seagate 500 GB SSD Hybrid 2.5" HD (iFixIt Product code: IF107-098-3). From what I've read, speed will be improved somewhat, but at the cost of using up battery life.
Alternatively I could up upgrade to 8 GB RAM and replace the HD with Toshiba 500 GB 5400 RPM 2.5" Hard Drive (iFixIt IF107-060-1). The cost would (roughly) be the same as above scenario.
Which of the two scenarios is better for battery life? Hybrid SSD/SATA HD? Or Increased RAM with standard SATA HD?
