The outstanding performance in IOPS allows the SN840 series to be used in a variety of enterprise high-load environments, such as virtualization, SQL, AI, and machine learning.

The storage capacity of this series starts at 1.92TB and reaches a maximum of 15.36TB. It uses 96-Layer 3D NAND for Ultrastar DC SN840, DC SN640, and DC SN340. The warranty period is a 5-year limited warranty.
