I'd also vote for crucial depending on your goals. I've been using them as my second choice after samsung for a long time, going back to the M4. Not top performers but good bang for the buck and highly reliable. In my current system I've got a samsung 960 EVO NVME 500 GB as my system drive and a 750 GB MX 300 as a secondary drive that I run virtual machines from. Got it for $139 on prime day though it's a lot more now. Anyway, going from a spinning disk to an MX300 will be like night and day even though its not a speed daemon as SSD's go.Crucial or Western Digital/Sandisk would also be good. Adata is also decent recently it seems.
What a useful information!
