NVMe Selection.

Latitude 5410
Windows 10 Pro

I want a 512 Gb 2280 NVMe ssd, PCI Gen 4 with backwards compatibility to Gen 3 to use with this Sabrent enclosure:

to boot Linux (independently). See my initial post:

My intention is to move it to the 5410 if my current WD internal SSD dies. Not going to spend a fortune on this combo as I can purchase an entire similar Latitude for approx $400. I have decided to go with a quality name for dependability sake.

My system came with a 2230 form factor but I understand I can I can put a 2280 SSD into the M.2 slot (without adding any new hardware) > ? btw, Not a gamer. General usage.

Read some nasty things about Sandisk's dependability > true ? My main concerns are compatibility, dependability, versatility and unknowns (eg heat in enclosure and 5410).

I know there's pros and cons to both SSDs but for my needs which is better ? (If decisively, why ?)
