1. Big!!
The boot time when going from a HDD to a SSD is huge, the apps/games starts faster etc.
I used the FF XIV Arr benchmark to measure the change from HDD to SSD on my own system and it was overwhelming.
You wont regret it a single bit..
2. I for myself decided that a mastervol. of 120 Gb was enough, the rest of my 256 Samsung 840 Pro is just for anything else than the OS, like games etc.
I then used the SHHD that my machine was build as secondary drive for documents, pictures etc..
The SHHD is faster than any of my old HDD, but cant compeed with a true SSD..
