Bought it on eBay, said it was basically pulled from a new laptop. No idea why they pull NVMe drives from new laptops though.
smartctl says “SAMSUNG MZVL21T0HCLR-00BH1”, the listing said “Samsung PM9A1”.

It was under $150.
Looks like it’s the HP one, the firmware is HPS4NGXH. That firmware was from 2024.
Might be faster then my old Crucial, not why I bought it though. Wanted more space.

The plastic screw for my iFixIt NVMe enclosure, is only good for flying onto the floor. Luckily, I have some small non plastic screws.
That nice enclosure, messed up my fingernail too. Not very long either. Now it’s bleeding. iFixIt screwdrivers have a weak magnet, only works with very small screws. A cheap Chinese screwdriver set, from Amazon, has a stronger magnet, until it doesn’t.
