While NVME seems to be OK (and fast), the 512 G disk space limitation is a potential issue. How much do 1-terabyte SSD's cost? I've ordered the Inspiron above. At CAD $600+tax how can you lose? 8 G ram on the older machine was more than enough, so 12 G should last for a while. I'm looking at home use, email, large spreadsheets, some convoluted bash scripting, web-surfing, and streaming including Netflix (720p) and Youtube (1080p), etc. My next machine after this one will probably have NVME, by which time the cost of a 1-terabyte SSD will have hopefully come down to something reasonable. -- Walter Dnes I don't run "desktop environments"; I run useful applications

I have M.2 in four machines (recently assembled). 2 - Run on Gentoo (one 1TB and one 2TB) 2 - Run on Windows 10 (had no choice :-/) Corsair Force MP600 M.2 2280 1TB and 2TB PCI-Express Gen 4.0 x4 NVMe All boxes are running very well, and stable, no issue with drivers. You just need to enable some options in the kernel (I think, very simple). Make sure your Motherboard and CPU is compatible with "PCI-Express Gen 4.0" or it makes not sense buying expensive NVME just to run Gen. 3

I'll leave others to comment on NVMe drives, I've not had any experience with these. Dell used to satisfy a sweet spot between price and performance, compared to other more expensive mass producers. I have not purchased any of their products for some years now. I found the choice they offer to customise some components was great, but as soon as you asked for something different in ways that matter to horsepower (CPU, RAM or graphics) the price offering stopped being attractive. Funny enough, the component which failed just after the warranty expired was not CPU, RAM, or graphics, but the PSU. Having suffered similar kind of failures with other mass market box-shifters I've learned my lesson. Have you looked at building your own box? The bang for your buck should go farther, because for the same money you should be able to get better components. signature.asc Description: This is a digitally signed message part.
