Since update 4.50 the PS4 now supports external hard drives to save your games onto. I finally ran out of storage on my PS4 Pro and I decided it was time to get a external drive. I went with the Seagate 5TB drive. It costs about $110.00. These drives also come in 1TB, 2TB, 3TB and 8TB. Set up is extremely simple, just plug in the drive in any of the PS4’s USB ports, then format the drive and it is ready to go.
