What exactly "needs" 800 MB/s speeds? That's Bytes not bits, right? But I guess any progress is good. Especially when my 150MB/s usb pendrive transfers at 330kb/s after 5 files.

Didn't Asus ROG Ally fry MicroSDs due to excess accumulated heat? It seems to me when you are getting to 800MB/s, the MicroSD slot would really start to benefit from a concrete cooling solution. Maybe you don't need a separate fan to cool the socket, but so far the MicroSD socket has just been thrown to any place that suits the general external design of the device and internally the PCB design. I reckon that was the problem in Asus Ally as well.

I was about to write... What about writing speeds and that read are not that important .... But if those SD cards can rival on 4k randoms etc a decent SATA SSD that would be huge for steamdeck owners or rog ally etc.

I wouldn't mind that for my Steam Deck. While it has fairly easy to update built in storage I still want more space and a 1TB SD card while nice to have makes games really tough to load.

Currently have a 400gb SD card and the write speed sucks. 30mb and 90mb read. It came with it when my fiance bought it for an xmas gift. Its the 256gb model. I dont really need to install any games on the nvme. I just want an SD card that has the speeds of at least a Sata 2 SSD lol. I stream games from a mini itx rig to my steam deck when I am at home, so I dont need more then 1tb of storage.

Strange question. File copies happen faster with faster drives 😉 I wonder if you're aware PCIE5.0 M.2 drives exceed 12GB/s now? 0.8GB/s isnt that fast today. Its good for USB though. A couple of years ago I bought a USB to M.2 NVME converter that gave me a 1TB Sabrent Rocket USB drive that does 600+MB/s. This speed hasnt been Sabrent Rocket science for some time 😉

I mean, yes. But all your stuff runs as slow as the slowest thing anyway. So you need a drive on your pc, the connector, the cable, everything to run that fast. I have noticed that the faster the drives get, the more unstable the connection is, so there seems to be a tradeoff.

Yeah they have to be up to the same speed, but I have multiple SSDs, NVME and SATA, plus a USB SSD too. Many people have converted to SSD only machines now. I saw over 800MB/s sustained on my cheap home brew 1TB USB SSD the other day 🙂 Though it needs a fan blowing at it or it disconnects and only a reboot gets it going again, easy enough to give it airflow. re: unstable connections. The only thing that makes any of my fast SSDs unstable is heat. Thats it. With good enough cooling there is never a problem ... ever.
