With Sony providing a comprehensive breakdown of the PlayStation 5 architecture, we finally have some answers to question Mark Cerny left lingering all the way back during GDC in March. Top of the list has been how Sony is approaching expandable storage, which we now know will support a wide range of consumer SSDs.
Earlier this year Mark Cerny confirmed that Sony would allow PS5 players to expand upon the internal SSD storage using off-the-shelf NVMe SSDs, a vastly different approach to Microsoft who have instead partnered with SSD manufacturers to create proprietary SSD expansion cards.
Sony’s approach allows for more flexibility in how you expand your PS5 storage but is constrained by a list that the company approves beforehand. That’s to ensure that the SSD you purchase matches the minimum 5.5 GB/s bandwidth, only afforded by brand-new PCIe 4.0 SSDs that companies like Samsung and Western Digital have started producing.
