Wednesday morning Sony released a "Road to PS5" presentation, a 52-minute technical breakdown of the PlayStation 5 hardware. During the presentation, Sony's Mark Cerny went through each of the PS5's core components, including its CPU and GPU. The key part of Cerny's PS5 presentation, however, remains the console's SSD. It's this drive that reportedly makes the PS5 such an incredibly fast next-gen console.

On paper, Sony lists the PS5's internal storage as a "custom 825GB SSD." An SSD alone is a huge upgrade over the PS4 generation's mechanical hard drives. A 825GB SSD is also a great start, given the launch PS4 came with just 500GB. But the most important word in that description remains "custom." The SSD in the PS5 is built to improve the PS5's performance to incredible degrees. Sony says it may even make loading speeds 100 times faster than the PS4.

According to Sony's early estimates, the PS5's SSD will have a throughput of 5.5GB/s of performance on paper. Yet due to the PS5's custom design, including a 12 channel interface between the SSD and the main processor, Sony says the SSD really outputs between 8-9GB/s of compressed throughput.

To put that into perspective, the Xbox Series X's SSD specs show that the console's custom SSD is about half of that at 4.8GB/s of compressed throughput. If the Xbox Series X is prioritizing power, the PS5 is prioritizing speed and agility. And the PS5's SSD and the design surrounding it is the reason for that.

In context, that means that the PS5's CPU will be able to communicate with data on its SSD at blisteringly fast speeds. As noted, it has 100 times more bandwidth for sending data from the SSD to the main chip, making load times extremely fast. Not just that, however, but Sony claims that the communication time it takes to seek that data is instantaneous. Imagine thinking about something you need to get from the store and discovering that it's in your hand already.

Right now, Sony's getting the technical details for the PS5 out of the way. These numbers may not mean a lot to Sony's PlayStation audience on paper. It looks like fans will just have to settle for these specifications for now. Sony will go out of its way to show just what these specifications mean for game performance in the months to come. Luckily, on paper, the numbers look great. Now Sony just has to prove that its hardware can deliver next-generation experiences.

The PS5 remains planned for release in holiday 2020.
