  1. Serial ATA Cable Assembly & Connector DESCRIPTION SATA is the next generation storage interface for PCs and low-end Servers. The current Parallel ATA bus is not able to meet the increased bandwidth and performance demands of current and future PC designs. This standard replaces the 26 position ribbon connector with a small flexible signal cable. SATA can be directly connected (hot plugged) to motherboards and back planes similar to current SCSI applications eliminating the need for cable completely. Tyco Electronics offers a full line of SATA cable assemblies and connectors to meet the server, desktop and notebook SATA applications.

  8. Parallel ATA Vs. Serial ATA • Parallel ATA uses a 40 pin ribbon cable • Serial ATA uses a 7 pin connector and cable

  9. Benefits of Serial ATA The Serial ATA specification is designed to replace parallel ATA with a software-transparent interface for “inside the box” storage. It reduces voltage and pin count requirements and can be implemented with thin and easy to route cables. • Low voltage requirement. Serial ATA requires only 500 millivolts (mV) peak-peak to support new silicon processes and higher integration. • Lower pin count. Reducing the pin count helps reduce board real estate requirements and enables more reliable connections on the board and the storage device. • Higher integration. Unlike parallel ATA, Serial ATA does not require 5-volt tolerant transceivers that can pose a hindrance to higher integration which utilize today’s and future silicon processes.

  15. The SATA/STA Collaboration Serial ATA and Serial Attached SCSI are the newest generations of ATA and SCSI. ~Leveraging industry standards, Serial ATA and Serial Attached SCSI allow customers unprecedented flexibility in choosing the right class of storage device to meet their requirements. • Serial ATA: • Originally conceived for desktops, Serial ATA’s new extended capabilities (SATA II) make it the likely choice in storage environments requiring configuration simplicity or optimal cost/capacity. • Serial Attached SCSI: • Conceived for mainstream servers and enterprise storage, Serial Attached SCSI is the likely choice in environments requiring best performance, scalability and reliability.
