XPS 8940, add 2nd 3.5" HDD

My new XPS 8940 has a 256 GB SSD and a 2 TB 3.5" drive. I would like to add a 2nd 3.5" Hard Drive to the enclosure. The chassis currently has a couple of unused Hard Drive cages. One of them is 2.5" and appears to be riveted to the chassis. The other unused cage is slightly bigger and held in place with screws, but still looks to be too small to fit a 3.5" hard drive. 

Is there any way to replace one of the smaller unused hard drive cages with a 3.5" cage?

@the bbdude  - I would assume the existing 2T HDD is GPT because Win 10 prefers format that over MBR, even below the 2T limit for MBR.

You will get faster boots and better performance if you install a PCI-e NVME SSD as your boot drive, especially if you'll be doing video processing, but that's your decision. You can clone the 2T HDD and move the image onto an NVME SSD, either with the cloning software that comes with the SSD or with Macrium Reflect (free).

If BIOS is currently set to RAID, rather than AHCI, you do have to take a couple extra software steps before doing the actual cloning, but they're all simple and easy.

Thanks again RoHe. I should have mentioned that I do already have a Factory installed 256 M.2 PCIe NVMe SSD for my C: (boot drive), in addition to the Factory installed 2TB HDD for D:, so the 10TB will be a 3rd drive I will add to the system.

Hi,

 

I hope you are doing good.

 

This computer is shipped with two empty 2.5-inch hard-drive cages and one SATA extension cable. The primary drive of your computer varies with the storage configuration. For computers:

  • with a M.2 solid-state drive, the M.2 solid-state drive is the primary drive
  • without a M.2 drive, the 3.5-inch hard drive is the primary drive

You would not be able to replace the unused hard drive cages with a 3.5" cage. Our support here is limited to the original configuration.

 

Regards,

Gopal

Since I removed the hard drive from the front, and moved it to the top, I reused the screws. The top cage did not have any screws. Perhaps when you buy the new HD it will come with mounting screws, I assume?

 

No changes to the bios. It will auto detect it once you power it back up... I recall I did rename mine (in Windows) as I did not like the letter it was assigned.

@kanadian-kaos Purchased hard drives usually do not come with screws. The screw size is listed in the Service Manual, #6-32 x 1/4".

Thanks all for your input.

Gopal - The Dell documentation on the XPS 8940 is incorrect. As kanadian-kaos correctly pointed-out, there are in fact (2) 3.5" hard drive cages in the XPS 8940. I received my Western Digital Purple Surveillance HDD, 10TB, 7200 RPM Class, SATA 6 Gb/s, 256 MB Cache, 3.5" from Amazon yesterday. It is now installed, initialized as a GPT drive and being written-to by my BlueIris security S/W. So my HDD overall storage configuration is:
C: 256GB M.2 PCIe NVMe SSD
2TB 7200 rpm 3.5" SATA HDD
E: DVD RW Drive
F: 10TB 7200 rpm 3.5" SATA HDD

So yes it is quite possible to install (2) 3.5" HDD's in the XPS 8940.

bbdude,

I want to do the same thing.  But I could not find the additional sata-power cable  or the data cable inside 8940.  How did you manage. Pl. explain.  I already got a HDD from amazon.  I have some extra screws. Thanks.

I just ordered the 8940 and am waiting for it to arrive in the mail.  It is coming with a 512 SSD for the OS, and a 3.5 1TB 3.5 SATA HDD.  I plan to remove the 1TB 3.5 SATA HDD and install two WB Black 8TB 3.5 SATA HDD.  I was so glad to see your thread here stating that you has successfully installing a second 3.5 SATA HDD.  

What I would like to know is if you needed to buy an extra cable to accommodate the second 3.5 SATA HDD?  And if so which one did you purchase?  Lastly , what else did you have to produce/purchase to complete the install, i.e. screws, etc?

I want to be able to purchase everything before the PC arrives so I can have everything ready to upgrade it right away.
