SSDs are the future of memory technology (for the time being), it reduces electricity used and will not only reduce the heat of your console but it will also make it less noisy, since SSDs do not have a disc inside of it which the HDD has. Think of the SSD like a HUGE memory card, thats basically what it is. The pros are really good, but the price is a con and its such a big con that it isnt worth it at the moment. I'll get an SSD in a year or 2, but i expect the next generation of consoles to have SSDs already stock in every console.
