Alright I'll give a little backstory here. (You can skip right to the questions if you want) I'm planning on upgrading my 2012 macbook pro with a samsung 830 ssd as a boot drive in the optibay. My original plan was to get a 256 GB drive to house both OS's plus all my apps and games which would just barely fit. I recently decided against this for the reasons of price and because my game collection is getting bigger than initially expected, I wasn't planning on getting anymore games at the time and with the ones I plan on getting it would put it over the limit. Plus I figure games don't need to be on an SSD anyways. I then decided to get a 128 GB SSD and just put my games on my HDD but that would be leaving a lot of unused space on my SSD which would probably never go to use. So this leaves me with a few questions. 1. Would 64 GB be enough to hold OS X with ~5 GB of apps and a W8 partition with no apps or anything? Keep in mind I took off the excess fonts in OS X which freed up a gig or two. 2. Is it possible to pick and choose which apps go on the SSD and which ones go on the HDD? or must you place the whole application folder on one or the other? Because COD4 and Doom 3 take up 8 GB's and I don't want those on the SSD. 3. If I add 16 GB's of RAM would that take away 16 GB's on storage? Isn't it true that when you put your mac to sleep it writes out your ram content to your drive and takes up however much space you have in your RAM? Or could I allocate this to the HDD instead? Thanks in advance to anyone who can help on any of my concerns, I'd be really grateful.
