I have a UX360CA with a 256GB disk and its starting to run low on space. I tried to installa a 512GB disk but the system didn't recognize it at all? I checked with the asus support team and they say that the maximum size on a m.2 nvme drive is 512, and that any disk with that size should do. I tried to install a 480GB but that didn't work either. So my question is, does anybody here have a UX360 with a 512GB disk? If so please tell me what brand and model so I can try the same disk in my machine.



  • If your model is an Intel base, please try to dlownload IRST from intel web site. I also think that you can find it from MyAsus app.

    I had the same issue as yours more than a month ago when replacing a 1TB by a 2TB. The BIOS can see my new 2tb (yours must see that new size first, if not it simply means that yours cannot take that size).

    I downloaded the IRST and put into my installation usb and browsed for it at the selection disk to install. If no IRST, you cannot continue...

    Its SSD can indeed be upgraded to 512GB.

    Please refer to the following FAQ for troubleshooting.

    Thank you.
