Decent burst read / write at around 1500 - 2000 MB/S
No DRAM cache.
TLC.
Struggles with sustained writes (1TB model will probably do slightly better than the model shown in the graph).
Cheap though!

DRAMless = slower performance and relatively shorter lifespan = not worth it.
You're not saving enough over a normal ~$100 unit to make it worthwhile.
