Is an SSD the same size as a laptop HDD? Or will I need a mount?
Depends. I've had laptops where you need to remove the motherboard to access the HDD and I've had others where you can remove/replace it by taking out a single screw.The laptop I'm going to be putting the SSD in (low end cheap HP 255 G3) requires a lot of stripping down to get to the HDD. Why do they make it that way? Didn't laptops used to have one simple panel at the back which you can remove to get access to the HDD
