SSD Upgrade for HP Omen 15 dc0003nx

[ssalmanali]

I want to upgrade my laptop HP Omen 15 dc-0003nx.

I have an existing SSD (256GB) which I want to upgrade to 1TB/2TB. 

Also, my laptop has a 1TB HDD which I want to upgrade to an SSD.

In addition, I already have 16GB of RAM. I want to add another 16GB stick. 

I need suggestions regarding compatible brands and specific model numbers.

Thank you so much in advance.

The specs for your model say it came with only a 1 TB hard drive:

Inside the laptop looks like this:

red arrow points to M.2 SSD

It can use a SATA or NVME M.2 and the latter is much, much faster. This SSD would work in either 1 or 2 TB capacity:

The hard drive is in the lower left corner of the picture and can be replaced with a 2.5 inch SATA SSD such as this:

You have a single 16 gb module and an open slot. Memory is SODIMM 16 GB 2666 MHz 1.2 v DDR4  937438-850:

Thank you so much for the prompt response.

However, I just needed one small piece of advice. Is it better to go with Samsung 970 EVO or 970 EVO Plus since there is not much difference in price where I live.

The PLUS was introduced a bit after the Evo so its newer hardware. However, you cannot go wrong with either one.
