Inspiron 15 7559 - Compatibility SSD M.2 PCIe / NVMe

https://www.dell.com/community/en/conversations/inspiron/dell-inspiron-15-7559-compatibility-ssd-m2-pcie-nvme/647f92e7f4ccf8a8de4cf19d

Hello. In regards to the post above, would an NVME work with an adapter for SATA?

To put in place of the original Drive?

An adapter like the following?

Thank you for your time.

No.  This system will not take an NVMe drive internally.  The only way to use on is with an external USB adapter, and then only for storage -- not as the boot drive.

Thank you very much. I have it booting Linux on an external NVME though.

I should have qualified that it won't work reliably with Windows from an external drive.

No, the Inspiron 15 7559 only supports M.2 SATA drives — it doesn’t have NVMe support.
An adapter won’t make an NVMe SSD work, since the motherboard lacks PCIe NVMe lanes.
Use an M.2 SATA III SSD instead for full compatibility.
You’ll still get a big speed boost compared to a traditional HDD.
