Hi, I have an XPS 8950 i7 on the way with 512 M.2 drive and 1TB SSD.

Debating replacing 512 with 2TB or placing the 2TB in the second slot giving me 2.5TB.

Been looking at the Crucial P5 2TB M.2 2280 NVMe PCIe SSD.

As I've never used M.2 before have no idea what potential shortcomings they have or ideal setup.

My last machine had a 2TB SATA as I copy a fair few large files including images so wanted to ensure the C drive didn't run out of scratch disk etc as would always buffer on C when copying big files on say D drive. Prefer to not move scratch disk allocation as had issues in the past.

That said my preference would be an M.2 2TB in slot 1 and the current 512 on slot 2, but have never duplicated M.2 drives and only had a dock/duplicator for 2.5 & 3.5 SATA.

Any recommendations from those who have tackled similar already would be appreciated.

Thanks.
