Disk On Module
From Free Knowledge Base- The DUCK Project: information for everyone
Disk on Memory, Disk on a Module or simply and more commonly Disk On Module (DOM) is a flash memory chip module that provides solid state storage and connects to an IDE (Integrated Drive Electronics) connector.
An IDE DOM is a small flash storage module which plugs directly to the IDE connector of the host motherboard. The DOM emulates a HDD, so the host operating system sees no difference reading and writing from an IDE DOM or rotating HDD.
