Having just recently bought a Playstation 4 Slim, I quickly became aware of the dilemma of storage. I read that PS4s “officially” support up to 2TB but people have been able able to use SSDs with much higher storage than that. Seeing that a 6TB SSD costs more than a brand new PS4 Pro, I decided to go with 4TB and hope for the best.
