It appears that an 80mm drive fits.

Not sure about the spec however.

Hi, 

According to the specs, it should work, but we have never tested this specific drive on the Alienware 17 R4. Some users confirmed issues with this type of upgrade, the issues are usually related to the system not recognizing the drive. You could try searching on different support forums (like Alienware Arena or Notebook Review) for this info, there may be users that have tried the upgrade and posted their results. 

Yes it definitely does support Samsung 960 PRO.

I am currently running an Alienware 17 R4 with a Samsung 960 PRO 2TB as my boot drive.

Hi,

I was able to format the drive (samsung 960 pro 512GB M.2) and see it in windows. But the samsung apps (for driver and firmware update) dont' see the drive. Do you happen to know how to make those apps recognize the drive? I want to use the data migration tool to switch my boot drive to it but I wanted to update the driver and firmware before...

turn off raid

 I have a 17 R3 and replaced my 256GB nvme with 960 PRO 1TB and have same problem with Samsung driver program not seeing the new drive. I used Migration to copy them then took the old drive out and installed in slot one for the boot drive. Seemed to work good but starting to have some blue screen failures. The only Bios setting is SATA operation and is set to RAID. Can only switch to AHCI. Should I switch to AHCI?
