introduction                 

        mini sas high density (hd) is the newest member of serial attached scsi interconnect family. sff-8643 is the interna version of sff-8644.both are called a "high density 36-pin mini-sas cable".mini sas hd 4i cable to support high data transmission, quality assurance, stable characteristics. applied to a large server, connecting intelligent cloud server and database server. connect high-speed network server and network storage devices.internal hd mini-sas4i  (sff-8643) to4×sata 7-pin, hd 36-pin to 7-pinl satacables function as a "hybrid cable"; thus permitting the installer to link up legacy mini-sas devices with the latest generation of mini-sas hd (high density) hardware.the high density (hd) system referenced as hd mini-sas (sff-8643) in the sas 2.1 standard, meets the6gb/ssas specification.  these new hd connectors will be used on the sas 3.0 specification when it is released.  cable material may change but the connectors will be the next generation of sas to run at12gb/s. all mini sas hd connectors have 4-channels, and are capable of connecting 4 devices and can fan-out to single channel connections.mini sas high density (hd) sff-8643 to 4×sata 7p hybrid cables are the newest addition to serial attached scsi interconnect family.                 

       mini-sas hd sff-8643 to 4×sata 7p(latch) cable

   internal mini sas hd sff-8643 to 4×sata cables maximize storage interconnection performance and space.

the drive connectors each havea 4-pin ide molex power connector.this internal mini sas hd hybrid cable is guaranteed to perform at speeds of 6.0 gbps per lane and features a sff-8643 connector on one end and four sata 7-pin

connector on the opposite end with latch.mini sas hd 4i (sf-8643) is a new generation of high density interface, small size and save the equipment space, bandwidth is wider and larger capacity, faster data transfer. 30u "gold plated contacts, electromagnetic compatibility (emc) design of fr4 pcb circuit board, signal grounding system, improve the stability of the signal transmission.                                                        

            the cable below has quad 7-pin sata connectors to one hd mini-sas (sff-8643) connector.these cables exceed the sas 2.1 and sff-8643 specifications.we offers a complete selection of internal and external mini sas hd cables. our cables are made with superior quality madison or leoni cable. we can build custom mini sas hd cables to your specified length or wiring. we offer competitive pricing.like the external hd mini-sas, this new connector uses less pcb real estate and allows higher port density for internal hosts and devices.  

                            mini-sas hd cables maximize speed and port density for adapter cards, servers, and switches.  

                         connector a = internal mini sas hd (sff-8643)       connector b =4×sata7pin female

                              data rate  = 12.00 gb/s  (6.00 gb/s)
