Do you need a PCIe 4.0 SSD to use Windows DirectStorage in games?
What is DirectStorage?
DirectStorage is an API that is part of DirectX. Microsoft has already implemented it into the Xbox Velocity Architecture found on the new Xbox Series X and Series S consoles and has since brought it to the PC, at first with Windows 11.
On a DirectStorage-compatible machine playing an enabled title, players will experience dramatically reduced load times thanks to the new API. Described by Microsoft:
DirectStorage isn't a fix for every game on every system, then, but eventually the ecosystem will grow. It's built into Windows 11 first and that's where you'll see the most benefit, but it is also going to be useable on Windows 10 but with a reduced impact.
PCIe 4.0 for best performance but not required
DirectStorage requires an SSD that conforms to the NVMe standard, which covers a wide range of storage drives. What isn't required is a PCIe 4.0 SSD, which means that even slightly older hardware will be able to take advantage of its benefits.
Obviously, though, the faster PCIe 4.0 SSDs will give the best performance. As they're now supported by both AMD and Intel, if you're building a new Windows 11 gaming PC you should absolutely be putting one at the heart of your system, like the superb Samsung 980 Pro.
One of the fastest SSDs money can buy
Reliability and performance is the name of the game with Samsung's newest, fastest NVMe SSD.
