track-to-track seek time

Thân thiện

Definition

1. Noun:
   • (Computer Science): The time it takes for a read/write head in a disk drive to move from its current track to an adjacent data track. This is a specific measurement of a disk drive's performance, representing the shortest possible seek time.

Usage

• As a measurement of performance: This term is used to specify and compare the speed of data storage hardware, particularly traditional Hard Disk Drives (HDDs).
  • The technical specifications list a track-to-track seek time of 0.8 milliseconds.
  • A lower track-to-track seek time generally indicates a faster, more responsive hard drive.

Advanced Usage

• In performance analysis: "Track-to-track seek time" is one of several seek time measurements (alongside average seek time and full stroke seek time) used to evaluate disk latency.
  • When analyzing disk performance, the track-to-track seek time provides the best-case scenario for head movement latency.

Variants and Related Words

• Seek Time (n): The broader term for the time it takes for a disk drive to locate a specific piece of data on the disk.
• Average Seek Time (n): The average time it takes for the read/write head to move to a random track on the disk.
• Full Stroke Seek Time (n): The time it takes for the read/write head to move from the innermost track to the outermost track, or vice versa.

Synonyms

• Adjacent Track Seek Time

Related Technical Phrases

• Access Time (n): The total time to locate and read data, which includes seek time, rotational latency, and command processing time.
• Latency (n): In this context, a general term for the delay before a data transfer begins, of which seek time is a component.
