    SATA Port Multiplier External Hub for windows and MAC

    The SS-3176HUB 1-to-5 native SATA2 Port Multiplier is designed to provide a high performance link between a single SATA2 host port and 5 SATA device ports. It expands one upstream SATA2 port to 5 downstream SATA2 ports. With its unique data aggregation and 3Gbps serial link capacity, it supports 5 SATA or SATA2 devices with auto-negotiation features over one single eSATA connector and supports both 3Gbps and 1.5Gbps devices automatically. It is able to take full advantage of 3Gbps host link bandwidth and FIS-based switching host controllers by bundling together data from device ports and sending it over the 3Gbps host link. TheSS-3176HUB is designed for optimum performance and expandability. With its hot-plug and hot-swap features, it is an ideal upgrade solution to support SATA and SATA2 devices for the rapidly changing data to preserve userˇ¦s investment in the SATA interface.

  • Flexible and Fast - our SATA II Port Multiplier PCB

    To connect multiple SATA drives to a Single SATA port idea, now is a reality, thank to Port Multiplier 1.1 specification SILM3726 - SATA II port multiplier enables the connection of multiple SATA drives to a single SATA host port for multiple storage applications. Combined with any SATA II controller, the our SIL3726 - SATA II port multiplier is the highest performance SATA port multiplier solution on the market. Base on SIL3726 chipset, the unique and sophisticated switching technology inherent in our SIL3726 - SATA II port multiplier is fully exploit the new SATA II signaling speeds of 3Gbps, as well as advanced host controllers that utilize Frame Information Structure (FIS)-based switching, NCQ such as, to create extremely high-performance yet cost-effective storage solutions.

    SIL3726 - 1 to 5 SATA port multiplier, a very reliable and extremely fast variety of storage applications can be accomplice, including home and consumer electronics storage (digital content and high-definition video), JBOD or RAID storage arrays, and server and workstation storage.

    Unlike other port multiplier, our SIL3726 - 1 to 5 SATA II port multiplier doesn't need to downshift its host connection from 3Gbps to 1.5Gbps when connected to 1.5Gbps hard drives. Instead, the advanced switching technology aggregates data to and from 1.5Gbps hard drives for transport at 3Gbps speeds over the host connection. When paired with a high-performance FIS-based switching controller like the eSATA-PCIX, which is capable of executing commands and transferring data to multiple drives concurrently, the SIL3726 - SATA port multiplier provides unequalled data throughput over a single SATA link.
