========================
It was stated that this model will support SATA or PCIe up to 512GB but I have to differ as the BIOS does not recognize a Crucial P1 NVMe PCIe M.2 500GB SSD. It currently has a 120GB SATA M.2 SSD stated above.
I had read that it will support up to 1TB SATA SSD. Can someone please clarify this. This is so frustrating that the manual (if you can find the right manual) does not state the specs for this.
Please help!

Hello cblackwell,
For 512GB SSD, we have tested M2 PCIE 3*4 NVMe ones by Samsung, Sandisk and Toshiba.
For SATA SSD, the largest we have tested is 512GB as well.
If you have issue installing new SSD, please kindly bring the device and the SSD you want to install to our service center.
Our agent can help you with it.
Thank you.
