Disk on Module

from Wikipedia, the free encyclopedia
IDE flash module

Disk on Module (DOM) is a module form of a flash memory that is intended for industrial PCs or for end users. Since the introduction of SSDs (around 2009), these devices have only played a role for old devices with IDE connections. With the help of a DOM as a replacement for a commercially available hard drive , a PC can be assembled that no longer has any moving or noise-generating parts, if the CPU and power supply are passively cooled and an optical drive is dispensed with.

Another important advantage is that this storage medium cannot be damaged by vibrations. If the data is often written to on these media (e.g. when used as a system disk), it is advisable to use modules that allow a sufficient number of write and read cycles.

The flash modules are available as DOMs in various designs ( IDE 40 or 44 pin) for plugging into the IDE port of the mainboard / controller or in the 2.5 ″ / 3.5 ″ hard disk housing with 40/44-pin IDE Connection or as a compact flash card. USB flash modules are among the latest technological achievements. These flash disks have so far appeared in the following designs: 2.5 ″ IDE flash disks, industrial CF cards, wide temperature, secure and embedded USB disk-on modules, with 40 or 44 Pin or in a horizontal or vertical version (USB). Depending on the version and model, the capacities range from 4 MB to 32 GB.
