Re: Ideally, I would like to use 2 SSD's. But I think I only have connections for one. you can get two, one in motherboard M.2 socket, the other in PCIex4 slot via a PCIe NVMe ssd adapter. Re: Should I get one with a heat sink? I don't do any gaming and generally put a light load on my computer. no need, but it does not hurt to have it. Re: Does the XPS 8940 support PCIe 4.0 x4? No.  8940 chipset is H470.  It has PCI Express Revision 3.0. Re: Will these fit? SAMSUNG 980 PRO SSD: yes. it has been done.

I want to upgrade my 500 GB SSD to a 1 TB SSD. I read on here that I should get a M.2 NVME 2280. But I still had a couple of questions. Ideally, I would like to use 2 SSD's. But I think I only have connections for one. Does the XPS 8940 support PCIe 4.0 x4? Should I get one with a heat sink? I don't do any gaming and generally put a light load on my computer.

This is the specific one: [URL] The second is a SAMSUNG 980 PRO SSD with Heatsink 1TB PCIe Gen 4 NVMe M.2. This is the specific one: [URL] I read that some M.2 2280 SSD's are slightly different sizes. Will these fit? Any suggestions on what I should get? Thanks Dan
