Hello 
I recently purchased an Adata SX8200 Pro 1TB from amazon and as luck would have it I noticed an article a day after arrival that states they have changed the controller on newer stock.
My sdd is of course the newer controller which is slower and I was wondering whether I should keep it or return it for another ssd?
Are there any other options around the £130 mark that would perform better than this new controller? I had looked at a PNY option or the WD Black SN750 but am unsure of what to do.
Any help would be greatly appreciated as I am very new to the M2 market.
Thanks!
