This is the only SSD in the market to use TLC NAND. TLC (triple layer) uses more power than the MLC NAND used in other consumer SSDs. It also has the lowest lifespan. Anandtech estimates that the program/erase cycle lifespan may be around 750 cycles for 2xnm chips. As NAND processes continue to be shrunk, that lifespan will also shrink.
TLC NAND's performance may degrade significantly over its lifetime, especially if it is written to quite a bit. HardOCP found that steady-state 4k testing caused the 120 GB drive to even flatline on read speed, the one thing that TLC drives seem to do well in (unlike write speed). This is the first TLC product in the market. Your mileage may vary.
