Alienware 15 R4 M.2 Slots Question

Good morning!

I understand the laptop has 3 SSD slots, and the two M.2 2280's have different compatibilities. One is SATA/PCIe NVMe compatible, the other is just PCIe NVMe.

I ordered mine with just one SSD installed, no other hard drives. My question is... Was the pre-installed hard drive installed at the PCIe/SATA slot or the PCIe slot? Which slot is which? 

Thank you,

Andrew

Here is the storage information for your system.

What pre-installed SSD do you have?

Hi @Alienware-Eimy,

Thank you for your quick reply!

The preinstalled SSD is a 512GB PCIe M.2 Class 50 SSD (make/model not specified).

Is there a standard as to where this should have been installed (which slot)? Or do I need to open up to check?

Thank you,

Andrew

It should be installed on the PCIe slot. One of the 2280 ones.

You can open it up and check, or check the service manual online.

Well I understand it has to be installed in one of the 2280 slots, just wondering which one since only one is SATA compatible.

The Setup and Specifications PDF does not say which slot (1, 2, or 3) is the PCIe only slot. I am wondering which slot is PCIe and SATA compatible, to know where to install a SATA SSD.

Thank you!

Same laptop.

I've bought and installed an M.2 SATA WD Blue SSD - Device Manager, Disk Manager, BIOS, all can't detect the drive!

What's going on Dell!
