The Supermicro SATA DOM (Disk on Module), known as SuperDOM, is a compact SATA3 flash storage module (6 Gbit/s) that can be conveniently inserted into a SATA port on the server motherboard to provide powerful solid-state storage capacity that simulates a hard drive. Supermicro SATA DOMs are extremely reliable with no moving parts like standard hard drives. They are smaller and lighter, offering significantly improved performance, lower latency, and reduced power consumption (~ 1 W-2 W per SATA DOM compared to 6 W-7 W for a hard drive).
