Windows 11 & DirectStorage; possible on external portable NVMe drive


 Share

Recommended Posts

Does an external M.2 drive - like Delock Thunderbolt™ 3 External Portable 480 GB SSD M.2 PCIe NVMe - also supports the new DirectStorage in gaming (on Windows 11)? Connected via USB-C (and more specifically in my case a compatible USB-C hub; the Satechi Type-C Multi-Port Adapter 4K with ethernet V2)

 

Or does DirectStorage only fully work when it's directly connected & plugged in into NVMe to the motherboard?

Based on nothing but conjecture you'd want fast streaming speeds to see a benefit with directstorage so I would think you'd want it on the PCIe bus alongside the graphics card, I would also expect the minimum speed requirements to be at the top end of PCIe3 (if it's even supported) to be vaguely comparable with the Xbox Series S/X (2.4Gbps before compression, 4.8Gbps after). So in summary if it's even supported I wouldn't expect it to perform well over USB3.

That's a interesting question, I'm just guessing here and say that it probably will work with externals as long as the minimum speeds are there.

Hello,

I have not seen any mention of using an externally-interfaced drive, so I think it may be likely be a feature that requires directly-attached storage.  If the drive were accidentally disconnected during use that could cause problems (game crashing at the very least, I would think), plus there may be some security (anti-cheat) implications as well if drives were externally attached via Thunderbolt.

If it's connected through Thunderbolt yes, it should work fine.  If it's through USB probably not.

 

But until the tech is actually released I'm not making any promises, obviously.
