PS4 Pro will support SATA III with 6Gbs transfer speeds

Sony's new PlayStation 4 Pro will enable faster data transfers and game startups

By Derek Strickland from Oct 13, 2016 @ 9:21 CDT

Sony has confirmed the new 4K-ready PlayStation 4 Pro console will support the SATA III interface, doubling the read/write and data transfer speeds of the original PS4.


With SATA III support, the PlayStation 4 Pro's hard drive storage can hit read and write speeds of up to 6Gb/s, or 600MB per second. This means games can potentially start up faster and data transfers will be much quicker. This is a pretty big deal seeing as the PS4 Pro can take 4K screenshots and 1080p 30FPS video, and SATA III will ensure these bigger media files are transferred to USB sticks much faster than SATA II.

In order to hit native 4K and upscaled 4K in its games, Sony's PS4 Pro has modest hardware improvements over the original PS4, including a 4.20TFLOPs Polaris GPU that sits below an RX 470 (likely 16nm FinFET), boosted RAM, and an overclocked Jaguar CPU. Sadly, the PS4 Pro won't launch with a 4K UHD Blu-ray disc drive, and here's why.

The PS4 Pro won't have any exclusive games and will play all existing PS4 titles, with only a portion of older PS4 games getting upgrades like 1080p 60FPS and native 4K support--check out the full list of confirmed games here.

The PS4 Pro will ship with a 1TB SATA III drive when it launches on November 10, 2016 for $399.
