Cerny says that SSD will push 5.5 gigabytes per second, compared to a mere 50 to 100 MB/s, meaning it can fill the system's 16GB of GDDR6 RAM in two seconds. The results, however, were 5.5GB/second - or about a hundred times faster than the PS4.

During the "Road to PS5" streamed talk today hosted by system architect Mark Cerny, he confirmed that nearly all Top 100 most-played PlayStation 4 titles will be backwards compatible on PlayStation 5 at launch.
