In case you didn’t know, the developers originally wanted an NVMe SSD that offers at least read speeds of around 1 GB / s. However, Sony looked, laughed and offered a 5-fold value.
PS5: Studios wanted 1 GB / s, but Sony quintupled that!
In a recent interview with Wired magazine, the lead architect of the Sony PlayStation project (Mark Cerny) mentioned that the developers weren’t even too picky about memory for the next-generation console.
After all, the vast majority wanted a simple SSD with at least 1 GB / sec. However, Sony had other plans, which of course were terrific. As you may know, the current PS5 proprietary SSD can provide 5.5 GB / s of information without any kind of compression, a figure that can reach almost 10 GB / s if we consider the compression algorithm.
In other words, Sony relied on technology that didn’t even exist at the time to create a 12-channel storage controller, and worked with Marvell to meet the PCIe 4.0 standard.
As if that wasn’t enough, the PS5 is also perfectly capable of using its super fast IP for compression / decompression of hardware data. Which, in turn, makes life a lot easier for developers when it comes to data loading.
This is exactly why games like Subnautica are 70% smaller on PS5, and other very demanding games like Control Ultimate Edition manage to reduce their size by at least 4K.
