The firmware update page on ADATA’s support site was minimalist. A single download link, a README from 2019, and a warning in all caps:
Internal SSD Firmware and Software | Samsung Semiconductor Global adata su630 firmware update
To update the firmware on your ADATA Ultimate SU630 SSD Go to product viewer dialog for this item. The firmware update page on ADATA’s support site
Early batches of the SU630 (like the 240GB and 480GB models) shipped with firmware versions that had occasional issues with SATA power state transitions. Users reported random disappearing drives after waking from sleep. Later firmware updates specifically addressed these DIPM (Device Initiated Power Management) conflicts. a README from 2019
