BD BD-R BDXL DVD-RW Player/Writer for Desktop PC

The maximum rate at which a BD‑R dual‑layer optical drive can read data from discs, expressed in bits per second or commonly used abbreviations such as MB/s or GB/s. This value indicates how quickly the device retrieves information for processing or transfer and allows users to compare performance across different drives.

The maximum write speed of a BD‑R dual‑layer optical disc drive, expressed as a multiplier (e.g., 6x, 12x). It indicates how many times faster the drive can write data compared to the base recording rate. This value helps users compare performance across different drives and choose one that meets their backup or media creation needs.

The write speed multiplier for BD‑R optical discs, indicating how many times faster the drive writes compared to a standard reference speed (e.g., 1×). Common values are 2×, 4×, 6×, 8×, 12×, and 16×. This metric helps users compare recording performance across drives.

The average time, measured in milliseconds, that a BD‑ROM drive takes to access data after a request is issued. It indicates the typical latency of the optical disc during read operations and helps compare performance across drives.

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 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 speed at which an optical drive can write data to a disc, expressed as a multiple of the base write rate (e.g., "5x" or "2x ~ 5x"). This value indicates how many times faster the drive writes compared to its standard speed and helps users compare performance across different models.

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.
