SSD Information

[FaithfulAsylum]

I want to install an SSD on my computer however, when I look at the M2 slot I have there is a SSD already there that came with the computer. I don't see any other slots for an SSD so my question is what is that SSD and can I remove it and install a different one? The one currently there is only a 258 GB and I want a much larger one. Also I don't see this SSD show up at all when looking at my hardrives on the computer. The only one that shows up is my C drive and my D drive that I already installed.

Hi

what is the exact reference of your computer, as you can see here, this indicates several possibilities

but for example

875-0029 Product Specifications

Edoras motherboard specifications.

One M.2 socket 3, key M for SSD (PCIe x4)

256 GB PCIe NVMe TLC M.2 Solid State

 ( hdd )Size: 2 TB

Interface: SATA

you have an m2 type ssd and a sata disk, I don't quite understand your remark
but if you have not modified the ssd, windows drive c, is on this ssd precisely
you should be able to, check

device manager / disk drive
indicated drives shown here
(at best image capture)

to replace the m2 ssd, with a bigger one, you can check the reference and look for the same for a bigger one, see this for example
