Best way to format a second hard drive in a MacBook Pro?
I put a SSD in my MacBook Pro and I am wondering what is the best way to format the hard drive that i am putting in the place of the optical drive. I could set it put in raid configuration but I'm pretty sure that it takes the speed from the slower drive. Making my upgrade pointless. Should I put the hard drive in and format it to Mac OS extended (journaled). Is this my best option. Will i only be able to put applications on the second hard drive or will i only be able to put on files such as media, word docs ect.?
MacBook Pro, OS X Mavericks (10.9.1), Macbook Pro i5 2.5ghz 13" Mid 2012
