The beta version of Sony's PS5 software is now available. It includes access to the long-awaited M.2 SSD slot. For select users in France, the USA, Canada, Japan and UK, the first PS5 beta is now available. Beta includes UX enhancements and customizations. But the most important addition is M.2 SSD expansion.Sony states that you will need an M.2 SSD with PCIe Gen4 read speeds of at least 5,500MB/s. This is largely what we expected, and it means that a wide range of Gen4 drives, including Samsungs 980 Pro and Western Digitals SN850s will be supported.However, you may need to take into account the cooling requirements when using an M.2 SSD with a PS5. Sony explains that an M.2 SSD must be used with a PS5 console to provide heat dissipation. One can be attached to your M.2 SSD by yourself in either a single-sided or double-sided configuration.Sony recommends Gen4 drives with read speeds of at least 5,500MB/s, but it can't guarantee that all M.2 SSDs meet the same specifications.This latest PS5 beta software includes M.2 SSD support and 3D audio support for built in TV speakers. This feature will be available in sound menu of the PS5s console system setting. It uses the DualSense controller for measuring the acoustics in a room in order to adjust a 3D audio level.Sony is also working on improving other aspects of its PS5 software. The Control Center interface will offer more personalization options to reorder or choose controls. PS5 users can view and send messages to friends and others from the Game Base in Control Center.Game Base's Friends tab is being upgraded with improved management options and the ability see how many of your friends are online. Sony will also address some of the confusion surrounding PS4 and PS5 versions. Different versions of games will now be displayed separately on the home screen and in the game library. Each title will also include information about whether it is PS4 or PS5.The new PS5 beta will include a trophy tracker, which allows players to quickly access up five trophies per video game via the Control Center. Sony will also offer the option to choose between 720p or 1080p for its PlayStation Now services. This new beta will also include a new automatic video clip that allows PS5 players to compete in high-score games.
