Inspiron 7559 not detecting Samsung 960 Evo M.2

My Inspiron 7559 is not detecting Samsung 960 Evo M.2. I have updated the BIOS and also intel drivers and Dell drivers. I have also tried to disable SATA (as I read this might help) however in BIOS 'SATA Operation' only has two options: AHCI and ATA -- I have it set to AHCI. I have also disabled 'secure boot' as have read this might assist. I have  tried the Samsung_NVM Express Driver and not surprisingly it does not detect the drive. Finally I have checked that the Evo is inserted correctly and it is. I have attached a doc with speccy info if that helps. Any advice  would be appreciated. Martin

Thank you for your message.

Inspiron 7559 has a Sata III interface & will work with Samsung 850.

Samsung 950 uses PCIe  NVMe interface which is not compatible with this model.

Make sure your system is on the latest BIOS - and that AHCI is enabled (the system likely shipped with RAID enabled).  You'll also need to load the Samsung NVMe drivers when you install Windows 10 onto the drive.

The 960 EVO is an NVMe drive.  Your system supports only SATA drives - you'll need to return the  960 EVO and get the SATA version (from Samsung that's the 850)

Not in this model - yes, there are Dell systems that support NVMe drives.  Your 7559 is not one of them -  you must use a SATA drive.

Why the notebook have the NVMe entrance? Can Dell update the BIOS to make it compatible? Does the motherboard have support?

I have the same question. Is it a BIOS/UEFI limitation or hardware limitation? It can't be added in future firmware updates?

I have dell 7559 indian version. I want to buy a ssd for my laptop. it has m.2 slot in it. so which ssd I should buy,

can you help me?

buy an m.2 ssd but make sure you buy one with sata interface (don't get confused by interface as connector, the logical interface is sata 3 the physiscal connector is m.2) so you must look to one ssd sata3 over m.2 connector

there's nothing like nvme entrance, the nvme is the logical interface and is the same as pciex4, the connector is m.2 or ngff that's only the physical form of the conector not the interface itself. you need a drive supporting sata3 over m.2 connector. not a BIOS thing it is a logical interface thing

It has the form factor M.2, but it doesn´t support "NVMe @ 3.5GB/s", just the "SATA @ 550mb/s"

Yes, the Samsung EVO 860 1TB will work fine. It's only the EVO 9xx that won't work in Inspiron 7559. I have a EVO 860 1TB in my Inspiron 7559 and it works, so I can say this from experience.
