New rMBP energy saver/ssd/sleep image questions

Hey guys I just purchased a new rMBP and I came from a 2010 15" with an aftermarket installed SSD, I remember I had to turn off "put hard disks to sleep when possible" because there was no point with an SSD if I am correct right?

Also I remember having to delete the sleepimage file/change hibernation code. I believe it freed up a bunch of space but is it needed for these newer machines? I mean why would they ask to put the hard disks to sleep when possible for an SSD, I would not want the HD to turn off if I am downloading something as well.

Thanks guys!
 
The default energy setting checks that put drive to sleep box, so I am going to assume Apple knew what they were doing. But to be honest, I have tinkered around with it checked and unchecked and I am not convinced it does anything either way on my 2013 MBA.

Mavs handles those images differently and does not use as much space as before. I would not mess with it.

Well what about file indexing and getting those loaded up every startup? Wasn't there a way to bypass that?

Is this true? So would 16GB RAM not take a 16GB sleep image file like it has in the past?

Well that is good to know. So don't have to delete the sleep image file anymore?:p

Correct. From what I read, the size is about 1GB. Regardless of how much RAM you have. No wonder people are gaining so much drive space when they install Mavericks.
 
I would leave hibernation at default (3). I just got the new r13 and changed it to 0 and deleted the sleep image to save space. Turns out the machine does not sleep correctly. I had nearly 90% before I closed the lid, the next day it was down to about 10%. I reverted back and all is well again. To save space I disabled local time machine image instead.

So even with the revert back to normal did you change hibernation to 0 or just leaving it all stock? :)
