ASUS ZenDrive U9M optical disc drive DVD±RW Gold

Indicates whether the product includes a built‑in Blu‑Ray reader capable of reading and writing Blu‑Ray discs.

Indicates whether the product includes a writeable optical drive, such as a CD‑RW, DVD‑RW or Blu‑ray writer.

The maximum speed at which an optical drive can read data from a CD, DVD or Blu‑ray disc, expressed as a multiplier of the standard base speed (e.g., 24×). This value indicates how quickly the drive can retrieve information for playback or copying.

The average time required for a CD‑ROM drive to locate and read data on the disc, expressed in milliseconds (ms). This metric indicates how quickly the drive can access information during operation. It is useful for comparing performance across optical drives of the same or different models.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

Indicates the mechanical configuration used to load optical discs into a drive, such as tray‑loaded, slot‑loaded, front‑loading or top‑loading. This attribute helps users understand how the device accepts media and can influence compatibility with different disc formats.

The average time taken by a DVD drive to locate and access data on the disc, expressed in milliseconds. It indicates how quickly the drive can begin reading or writing after a command is issued, affecting overall performance for media playback and disk operations.

The maximum write speed of a DVD+R double‑layer optical disc, expressed as a multiplier (e.g., 6x, 8x). This value indicates how many times faster the drive can write compared to the base speed of a standard single‑layer DVD. It helps users compare the performance of different drives and choose one that meets their recording time requirements.

The physical diameter of an optical disc, expressed in a length unit such as millimetres or inches. This measurement indicates the size of the media that can be used with compatible drives and helps users verify compatibility with devices and storage cases.

The type of optical drive included in a device, such as DVD‑RW, DVD‑Writer, Blu‑Ray RW, or no optical drive. This attribute indicates whether the product can read or write optical media and specifies the particular model or capability when available.

The physical connection types that a PC product uses to interface with other devices or peripherals, such as HDMI, USB, Ethernet, DisplayPort, VGA, DVI, SATA, and similar cables or ports. Each value represents one distinct connector or cable type that the product supports for data transfer, video output, power delivery, or networking.

The maximum number of input/output operations per second that a storage device can perform when writing data randomly, typically measured with a 4‑KB block size. This metric indicates how quickly the device can handle small, non‑sequential write requests and is useful for evaluating performance in database or high‑transaction workloads.

Indicates whether the device can perform continuous, non‑interrupted write operations (sequential writing). A value of "Yes" means the device supports this capability; "No" indicates it does not.

The length of time for which the manufacturer guarantees that the product will be free from defects in materials and workmanship, typically expressed in years or months.
