Computer Hardware

Among the given secondary storage devices:
- Optical Drives are relatively slow because they involve mechanical movement.
- Magnetic Tape Drives are the slowest, as they require sequential access to data stored on the tape.
- Hard Disk Drives (HDDs) are faster than magnetic tapes but slower than solid-state drives due to the mechanical nature of spinning disks.
- Solid State Drives (SSDs) provide the fastest access times because they use flash memory and have no moving parts, allowing for near-instantaneous data retrieval.
Thus, the fastest access time is provided by the Solid State Drive (SSD).
Therefore, the correct answer is .
