The article doesn't mention "pseudo", so I guess you're implying that these are just their existing flash that's capable of TLC/QLC, used permanently in SLC mode? 60DWPD for 5 years is basically 100K endurance, the same as true SLC.
Either way, that's great news - and the ~$0.32/GB they mention (only $600 for 1.92TB!?) for Micron SLC is absolutely amazing value, if you consider that this other article I submitted not long ago mentions ultra-cheap TLC SSDs with NAND from an unknown manufacturer costing $0.10/GB (I even have a comment there lamenting the lack of logically-priced $0.30/GB SLC SSDs!): https://news.ycombinator.com/item?id=35382252
