Thanks for everyone's shopping tips. There is no question that there are better drives than the one I selected. They don't appear better for what I needed, but everyone's needs are different and mine are very particular. - the Dell XPS is quite old and long in the tooth (2017?). It doesn't make sense to invest much in it at this late date. It does have some nice features: UltrHD display, nVidia GeForce GTX Mobile, 32GiB RAM) - I have no idea what level of NVMe it supports but it is old enough to not support HMB. So newer NVMe standards won't help this computer but would help more modern ones. - It's not my main computer so it doesn't need massive space. I needed at least 256GB. That's enough for Win 10 and Fedora. 512GB feels more comfortable. I went with 1TB since 512 wasn't much cheaper but 2T was significantly more expensive.
