Newbie question about SSD's
This is probably a really dumb question but here goes. I have a MacBook Pro with a SSD. I am trying to get as much battery power as possible and know that putting the drive to sleep helps battery power. Does a solid state drive need to be put to sleep? Thanks for taking the time to answer.

OK. A HDD consumes energy when it spins-up and loses it when it spins-down. It working speed, it consumes energy during reads and writes. There should also be some energy required to keep the platters spinning at constant angular speed, but not that much.
SSD, on the other hand, do not consume energy while spinning-up because they don't spin-up. The don't lose energy while spinning-down because they don't spin down. They consume energy for reads and writes. However they require no energy to maintain constant angular speed because they don't spin.
What all this gets down to is that SSDs don't consume much energy. If they don't consume much energy, then SSDs can't save much energy. Putting the drive to sleep has little to do with it.
It is not 1994 any more.
