The 5570 M.2 is compatible with NVMe/PCIe and SATA.

Which generation of PCIE it supports?

how many lanes it has?

Also share DELL Specification where they mention supporting of NVME.

Whats the maximum read/write speed it supports.

Thanks!

Best Regards,

Maalik

If you already know this then why do you ask.

If you would take the time to read the manual you could find the answers to your questions.

PCIe Gen3 (8 GT/s)

Perhaps because you linked to the Storage specifications page, which lists the amount of storage limit for each potential drive, rather than the System specifications page, which lists the external bus frequency, PCIe Gen 3, as the OP had asked for in the first line of their first post.

This leads me to my question...

Is a 2 TB SSD compatible, considering the Storage Specifications page lists a HDD up to 1 TB and both a 2.5 and M.2 SSD up to 512 GB?

Yes. Here are guaranteed-compatible SSDs from Crucial, though you may choose any brand you like. 

Dell's specs are based on what they test when the laptop is designed. It's not a limitation. Technology evolves, and often larger RAM sticks and larger drives become available after Dell publishes the specs, and Dell does not bother to go back to revise the maximum specs. So, Dell's specs should not be interpreted as limitations or maximums.

Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. I know many people do such work without this, but it's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard.
