What type of connector uses an 80-pin configuration to provide power and data for SCSI?

The Single Connector Attachment (SCA) is specifically designed for SCSI (Small Computer System Interface) devices, utilizing an 80-pin configuration for both power and data connections. This design simplifies the cabling for SCSI systems, as it allows a single connector to handle both power and the transfer of data, reducing clutter and the potential for configuration errors.

The SCA connector is commonly used in environments where multiple drives are frequently added or removed, such as in RAID (Redundant Array of Independent Disks) setups, since it offers hot-swappable capabilities. The integration of power and data lines within the same connector not only streamlines the process but also enhances reliability, as there is less opportunity for loose connections.

While other options, such as Parallel Connectors or ATA Connectors, are associated with different types of connections and standards, they do not match the specific requirements and functionality of the SCA in the context of SCSI connections. The Serial Connector option also refers to different interfacing methods that do not align with the specific 80-pin SCA connector design used for SCSI systems.
