Latitude 3390 pcie / nvme ???

Have a look at the following video for the 3590. The SSD M.2 slot should be in the same location I believe.

Thanks for the response, but that isn't there on the 3390. 
I have seen that they have a caddy where you can mount an M.2 SATA drive. But that is SATA. The docs clearly state that it supports PCIe. The only thing I can think of is if they sell a different caddy that has its own cable that connects to the motherboard. 

For example here is the SATA cable:

and the caddy:

Thanks again.

Hi,

I'm also interested in installing M.2 NVMe in 3390.

Have you got any results? The idea of special caddy for NVMe sounds reasonable, but there is nothing about it when searched online. The motherboard looks, like there is some connector near the SATA connector that might be for M.2

Ok, I was just looking at Latitude 3379 and the motherboard looks very similar to 3390.

Check here, page 18, you can see how a NVMe would be installed on 3390, but it's probably missing the M.2 socket and thus impossible to install NVMe.

So if you open your 3390 and don't see a socket there, you might be victim of marketing (probably someone edited the 3379 user guide to 3390 and just forgot to erase the NVMe part)

If I'm ever super poored and don't value my 3390 anymore, I might solder a M.2 socket to try

Helpline Confirmed there is a SSD Slot. But Dell Technician, who opened my system could not able to find SSD Slot. he suggested me to use 3.5 Type SSD in place of HDD

Dell is just lazy. There is no NVMe, only M.2 SATA

My solution is to never buy Dell products again. I also have a Dell IPS LCD with terrible burn-in (only 10 min to retain a image).

I know, old thread but maybe this will help others that run into this thread in the future with their 3390. I just bought one the previous week refurbished and it came with the Crucial 512GB 2.5 SATA SSD and have already sussed out the NVME situation for this Dell.

You need an NVME interposer caddy that replaces the existing SATA 2.5" cage as the 3390 can ONLY support one drive internally, so replace your 2.5"HDD/SSD with either an m.2 (SATA) or with the interposer board and second cable, it becomes your NVME in a sturdier caddy that allows you to screw in the imposer board and then that replaces the existing HD/SSD.

The 3590 shows the NVME drive in a totally different spot. The battery is smaller (I think) and the HD/SATA SSD is in a different spot towards the back of the laptop. Again, need to remove the existing 2.5" drive and slot in the NVME. Essentially, the slot for the NVME drive is ON the motherboard, along the edge to the right of the battery (when looking at it from the front).

The 3390 has the drive caddy to the left of the battery and can be HDD/SATA SSD or m.2/NVME.

Hope this Helps.

@ciddyguy​ What is the interposer board? Are you able to send a link or provide a product number for it?

@rpbritton​ Sorry for the later reply, just seeing this. I mispoke. The 3390 2n1 only does SATA. That is, there is no extra connector for NVME. The imposer allows you to convert from say, SATA interface to NVME, and allows you to also mount an M.2 form factor SSD into the 2.5" drive caddy spot but in this case, you are forced to run the new drive through the SATA interface. They make one for SATA to IDE even if you want to run a newer SATA drive in an older IDE based laptop, like an early 2000's Inspiron laptop that still uses IDE.

That is all an imposer is for. HTH.
