Samsung used triple-level cell (TLC) memory for their new 980 pro SSD's, which is a severe departure from their previous models, which used TLC memory for the EVO models and multi-level cell (MLC) for the pro series. TLC memory has greater storage density than does MLC memory, which allows for less expensive drives, but MLC has faster data transfer rates and greater write endurance, so I am both displeased and confused about why Samsung would do that; why did they not simply continue their traditional trend, with having the pro series use MLC memory, and use the TLC memory in their EVO series? Also, does this mean that no memory manufactures shall use MLC memory, ever again?
