Waste of time really. PS4/X One (X) are limited in transfer speeds of SATA III. Wouldn't take advantage of an SSD. A good quality HDD will do a better job.
waste of time? On my pro loading times are 2x faster minimum, some games such as FF XIV or wreckfest 4x. When some games has 1 or 2 minutes of loading times, 2x faster is worth
