870 EVO vs 870 QVO at 2TB
The 870 EVO uses TLC NAND for strong, consistent performance and endurance, making it the safer all-round pick. The 870 QVO uses QLC to lower the price per terabyte, which suits large, mostly-read storage but has lower write endurance and slower sustained writes. For a system or frequently written drive, choose the EVO; for cheap bulk capacity, the QVO.
