My take is crucial mx500. I dont consider samsung 860 evo as budget ssd. In my eyes they are consider expensive.
Crucial is Micron. They make their own NAND flash and their own DRAM. They only buy the SSD controller from 3rd party.
The supply chain is consistent unlike Kingston which is just an assembler. If their NAND flash runs out of stock , they simply go buy from someone else , therefore you might get different performance numbers from different batches of SSD. It happened before.
