Cable-less SATA Power

Innodisk’s SATADOM SSDs provide an elegant, compact option for SSD storage in embedded systems, industrial PCs and server motherboards with their small form factor that connects directly to the SATA connector on the motherboard. This simplified SSD design not only frees up a precious drive bay for other storage options but eliminates messy, obtrusive SATA data cabling. Innodisk’s patented Pin7 and Pin 8 SATA Power technologies take the cable-less concept to the next step by also eliminating the need for power cables for a 100% cable-less, shock resistant, space saving plug-and-play storage solution that optimizes airflow and makes the best use of limited board space in embedded and rackmount server systems.


Pin 7 Technology

Innodisk’s patented Pin 7 Vcc technology taps the normally underutilized 7th pin in the SATA connector standard to supply power to the SSD, letting SATADOM SSDs become a 100% cable-less solution. Pin 7 technology maximizes board space and improves reliability of the power connection compared to external cabling.


  • How Pin 7 Works

Traditional SATA storage takes the form of a 2.5” or 3.5” drive installed in a drive bay and connected to the host system through a SATA data cable with a separate power cable going to the power supply. The 7th pin on the SATA connector in this case acts as a ground wire to improve surge and transient protection and maintain signal integrity.

With Innodisk’s SATADOM design, the SSD is shrunk and installed directly on the SATA connector itself. As the SATA signal goes directly from the SSD to the connector without travelling through lengthy cabling, signaling robustness is improved and the 7th pin becomes redundant. Pin 7 Technology drives Vcc to this unused pin to power the SATADOM SSD without the need for an external cable. Through Innodisk’s patented design, this power supply through the 7th pin does not interfere with the high speed SATA differential signalling on adjacent pins.


  • For Embedded

Without messy, space-hogging cabling, Innodisk SATADOM with Pin 7 technology provides an ideal SATA based storage option for embedded systems that maximizes board space usage and optimizes air flow. A variety of form factors in various sizes, shapes and both vertical and horizontal configurations allow SATADOM with Pin 7 to fit into almost any embedded system and provide compact, reliable, cable-less flash storage.


  • For Servers

SATADOM with Pin 7 provides a solution to messy, cable-cluttered server interiors. Freeing up a drive bay for hot swappable storage, a Pin 7 enabled SATADOM sits directly on the SATA connector to provide easy-to-install flash storage for a boot drive, OS storage or extra space. Without messy cabling, the compact SATADOM improves server airflow, reducing cooling costs for the system.


  • Using Pin 7

Introduced in 2012, Pin 7 power support has been integrated into a number of embedded and server motherboards from leading providers including Intel . Pin 7 power support can be either through manual jumper selection or Innodisk’s Pin 7 circuit design. Motherboards with manual jumper support for Pin 7 will supply Vcc power to Pin 7 when the proper jumper is selected, and retain it as ground otherwise. Motherboards using Innodisk’s Pin 7 circuit design will incorporate a Pin 7 detection circuit which supplies Pin 7 Vcc power to the SATA connector when an Innodisk Pin 7 Cable SATADOM device is connected, yet maintain Pin 7 as ground when a non-Pin 7 device is installed.


Pin 8 Technology

Pin 8 is Innodisk’s latest cable-less SATA power delivery mechanism for SATADOM that provides Vcc power using the connector itself through extra pins on each side, maintaining SATA specifications for the standard pin connections while improving system reliability. With Pin 8, Vcc power is supplied directly to the SSD without external cabling and the physical Pin 8 connector design also increases reliability of the SATA connection against shock and vibration.


  • How it Works

Innodisk’s Pin 8 technology uses extra pins on both sides of the connector to supply Vcc and Power in a simple and robust fashion through the connector itself. The main SATA pinout configuration is left to standard specification. Pin 8’s angled power and ground pins not only provide Vcc current but also compress against the SATA connector when mated to create a robust physical connection resistant to shock and vibration, increasing system reliability in extreme environments.


  • For Embedded

Innodisk’s patented Pin 8 power technology adds extra reliability to embedded system storage by improving the robustness of the storage connection. The extra pins compress against both sides of the SATA connector for a more robust physical connection that stands up to shock and vibration. 


With the ubiquity of SATA as the storage standard for embedded systems and industrial computers, SATADOM with Pin 8 technology provides embedded systems a simple and elegant way to add flash storage that maximizes board space, optimizes airflow, and improves system reliability.


  • For Server

Supported on some of the latest server motherboards from tier-1 providers, Pin 8 Power technology provides a perfect solution to the problem of adding moderate amounts of flash for boot drives or redundant OS storage. Rather than taking up drive bays and adding messy cabling, SATADOM SSDs with Pin 8 technology take up only the SATA Connector itself to provide reliable, convenient flash storage for independent or redundant OS storage, freeing up drive bays for high capacity, hot swappable SSDs or hard drives.


  • Using Pin 8

Pin 8 technology is currently supported on some of the latest server motherboards from tier 1 providers including SuperMicro and Gigabyte. The simplified power design of Pin 8 technology makes it easy for motherboard providers to integrate and both Pin 8 SATADOM drives and non-Pin 8 SATA drives can be used in the same socket without reconfiguration or detection circuitry.
