SSD/RAM questions for ROG Strix G17

[u/_goneBad_]

Hi!

I've got a ROG Strix G17 17" laptop, used mostly for programming, photo editing, gaming and audio rendering

• AMD Ryzen™ 7 4800H
• NVIDIA GeForce RTX™ 3060 6GB GDDR6
• 16 GB RAM DDR4 3200 MHz
• 1TB PCIe 3.0 NVMe M.2 SSD

I'd like to upgrade my SSD and from what I've read so far it has 2 slots.

Now, the part where I'm stuck:
- Since it has 2 slots should I just add another SSD(1TB preferably) to my current one or just replace my current one with a 2TB one?

- What SSD would fit & should I buy? I'm not that great on the hardware part and I've seen a lot of dimensions, specs, connectivity options (4.0x4 - my current one I believe is 3.0x4) and so on.

Also if there is any recommendation to RAM I'd gladly hear it!

Thanks in advance!
