Fervit M.2 Mini-SAS HD to U.2 Cable SFF-8643 to SFF-8639

SKU CH-4QY8-KH5R7

Connects an SFF-8643 Mini-SAS HD port to a U.2 NVMe SSD using 28AWG copper wire and a signal-conditioning IC for stable 6Gbps data transmission

  • Signal-conditioning IC chip stabilises data and cuts interference
  • 90-degree right-angle SATA connector saves server space and eases routing
  • Converts one SFF-8644 Mini SAS HD port to four SATA 7-pin ports for multi-drive expansion
  • 28 AWG pure copper wire delivers steady 6 Gbps bandwidth for HDDs, SSDs and RAID
  • 2 metre length supports long-distance wiring in large rackmount servers and storage arrays

Connection Purpose

This Fervit cable bridges an M.2 Mini-SAS HD 8643 port to a U.2 8639 drive bay, enabling a direct link for PCIe NVMe SSDs in server or workstation builds. The 28 AWG pure copper conductors carry data at SATA 6Gbps rates while the built-in signal-conditioning IC keeps transmission stable over the full run.

Fit and Limits

The 90-degree right-angle female SATA ends help route wires cleanly inside tight chassis, making it suit integrators who need tidy cabling in dense enclosures. Builders requiring a straight-back connector or a different pin-out such as SFF-8644 to four SATA ports should select an alternative cable assembly.

Deciding Specification

The cable terminates in SFF-8643 on one side and SFF-8639 on the other, so the host must present an 8643 Mini-SAS HD interface and the target drive must accept an 8639 U.2 connector for the link to function.

Questions about this item

How can I verify the cable is working after connecting a U.2 NVMe SSD to an SFF-8643 port?

The built-in signal-conditioning IC chip stabilises data transmission and reduces electromagnetic interference, so the drive should be detected at full 6 Gbps bandwidth without errors.

What comes in the box and what must I source separately?

The package includes the 2 metre M.2 Mini-SAS HD to U.2 cable with SFF-8643 to SFF-8639 connectors; you must supply the host with an SFF-8644 Mini SAS HD port and the U.2 PCIe NVMe SSD.

Which version should I choose for a 90-degree right-angle SATA installation in a tight server chassis?

This cable features a 90-degree right-angle female SATA design that saves internal server space and improves cable routing flexibility for multidrive storage expansion.
