A Disk on Module (DOM) is a non-volatile computer memory that connects directly to a motherboard and acts as a hard drive. It is similar to flash memory and is used in environments where a traditional hard drive would not be suitable. It has no moving parts and takes up less space than a traditional hard drive, but if it becomes corrupted, data may be lost.
A Disk on Module (DOM) is a type of computer memory that is connected directly to a motherboard via a data connection and acts as a hard drive. This is non-volatile memory that does not require power to hold data and is actually similar to the flash memory used in other devices. A Disk on Module is typically found in applications where a Hard Disk Drive (HDD) would not be suitable due to the environment in which the computer is being used. It works in much the same way as a Solid State Drive (SSD), and DOM corruption can render data unrecoverable.
The appearance of a Disk on Module is similar to a stick of Random Access Memory (RAM), although it is typically somewhat thicker in size. A DOM is usually designed with pins that allow it to connect directly to a data connection for hard drives on a motherboard. It can use the same type of connection as a standard HDD, but doesn’t require a ribbon cable to do so, instead plugging directly into the board. This allows a Disk on Module to take up much less space in a computer than a standard HDD or larger SSD.
In most cases, however, a Disk on Module can be used as a hard drive, just like other types of storage on a computer. It is non-volatile memory, which means that it requires no power to save data. This is in contrast to volatile memory such as RAM which loses stored information once the power is turned off.
One of the major benefits of a Disk on Module is that it has no moving parts or a physical disk that is read for data. Hard drives that use a disk, such as an HDD, have an optical drive that scans the disk as it physically spins to retrieve data. If the disc becomes damaged or the player malfunctions, the drive may be damaged. This often occurs if someone drops a HDD, while dropping a DOM doesn’t necessarily damage internal components or the data on it.
One major drawback to using a Disk on Module for storage, however, is the way the data is retrieved. If part of a HDD with a physical disk is damaged, other parts can still be read using special equipment and software to recover the data on it. However, a DOM cannot be accessed this way. If part of a Disk on Module is damaged, the entire drive may be inaccessible and all data on it will be lost.
