I own a Lenovo Y510p Ideapad which comes with an Ultrabay slot allowing me to swap out my CD/DVD drive for another graphics card/cooling fan/storage device. I plan on buying a 256gb SSD, and here comes my question. Can I use my SSD as my main drive for the OS and shift the built in HDD into the Ultrabay slot? Is 256gb enough/too less/plenty since I won't be playing games on my SSD....only for the OS and respective programs? Thank you.
