my desktop comes with a 'Samsung MZVLW256HEHP PM961 256GB M.2 NGFF PCIe Internal SSD NVME - OEM '
it is dram based SSD, and is quite good.
To upgrade to 1TB Dram Based NVME M2 SDD, I have following to choose from:
Kingston A2000 $134 - budget choice
Crucial P5 $179 - mid range price
Samsung 970 EVO Plus $199 - best
any other brands to choose from?
