I recently got an amazing deal on 2 high capacity SSDs. I was able to easily install one of them on my husband's laptop for extra storage, but his already had a smaller SSD for the OS. Now, I'd like to install the otehr SSD in my (older) PC, but I don't think it's as easy as it was in the laptop. I know I have an open slot on the motherboard, but do I need to by my own SATA cable? And most importantly, I'd like to know how to transfer the OS over to the SSD without replacing the other hard drive. Thanks in advance!
