If the Xbox Series X is a lion, then the PS5 is a cheetah--this console's SSD tech is lightning-fast. Sony's next-gen console has a custom PCIe 4.0 SSD that can push compressed data at up to 9GB/sec, or almost twice as fast as the Xbox Series X's max compressed data throughput of 4.8GB/sec. This means the system will be able to access compressed data that's downloaded or from a disc much, much faster. Blu-ray disc game installs will be blindingly fast.
Once the data is decompressed, the system can process it at 5.5GB/sec, which also roughly twice as fast as the Xbox Series X's 2.4GB/sec decompressed data I/O throughput. PS5 architect Mark Cerny confirms the PS5 can load 2GBs of data in just 0.27 seconds.
