Oh man, where do I even start with this whole SDEX2M2 Adapter thing? It’s like someone decided, “Hey, let’s take the Nintendo Switch 2 and do something wild with it.” And, seriously, why does everything tech-related sound like a secret code? Anyway, the big idea here is pretty straightforward, I guess. They’re making an adapter so you can use an M.2 NVMe SSD with a MicroSD Express card port on the Switch 2. Open source, mind you. And it’s kinda cool they’re throwing it up on GitHub for everyone to poke at.
Now, Nintendo isn’t exactly chill about people fiddling with their stuff. But, lo and behold, this project’s already up and running just after they launched the Switch 2. Kinda exciting if you’re into tweaking stuff.
Here’s the nerdy bit. The Switch 2 supports SD Express 7.1. (Yeah, I know, more jargon.) Basically, it means you can hook it up to PCIe Gen3 x1, with the NVMe protocol doing its thing. The adapter just remaps some pins. Sounds simple? Maybe — or we’re just getting bamboozled by techy talk.
Oh, here’s another curveball — they reckon you could save some cash on storage. Like, instead of shelling out for a pricey PNY card, you could jam a bigger Sabrent one in there. Double the space, same price — who wouldn’t want that? Caveat? You gotta get or build the adapter first. Ha, why is nothing ever easy?
But don’t run off to grab any random SSD. Nope. It has to be a chill, low-power one, or you might fry your Switch 2. Seriously, NVNTLabs is waving a big red flag about this. Also, don’t, like, stick this into the original Switch’s slot. It’s NOT the same thing, apparently.
Oh, and what if — big “what if” here — you could stick in an external GPU too? I mean, why stop at storage, right? Sure, PCIe isn’t just for keeping files. It’s how we get all sorts of fancy doohickeys talking with your computer, like graphics cards. The Switch 2 rocks an Nvidia Ampere GPU — could we, hypothetically, push it to the next level with an eGPU?
Cautiously optimistic but, of course, we bump into another fun barrier. The PCIe Gen3 x1 tops out at 1 GB/s. Compare that to USB4 and OCuLink at 40-64 Gbps. Kinda feels like expecting a garden hose to power a fire truck. This idea might need, well, a bit more hacking. Also, sorting out the video output to bypass the built-in GPU sounds like wizardry.
In the end, who knows? Maybe the eGPU dream’s out there somewhere. But for now, keeping an eye on this wild adapter project is enough to get the tech modding juices flowing. Cool stuff, really.
