...you're describing what the SN550 was until they switched from TLC to QLC.
So they downgraded the SN550 and released a new model that's "superior", but actually is just what the SN550 was...
WD is acting really f***ing scummy. Who knows if they're even honouring warranties anymore?
I'd rather buy a Hynix.
