SMUGDESK M.2 SFF8643 to 4×SAS SFF8482 Converter Cable 1m

SKU CH-BTC9-M1Q97

Converts one M.2 SFF8643 port into four SFF8482 SAS/SATA drive connectors at 12Gbps for storage expansion

  • Expands one M.2 SFF8643 port to four SFF8482 SAS/SATA drive ports for mass storage
  • 30AWG low-loss copper wire maintains stable 12Gbps bandwidth for enterprise-grade RAID arrays
  • Plug-and-play design enables quick installation with server RAID controllers and NAS systems
  • 1m length supports tidy internal routing in rackmount servers and high-density chassis
  • Precision-shielded harness minimises signal interference for reliable long-term multi-drive operation

M.2 SFF8643 to 4×SAS SFF8482 Converter

This converter cable expands a single M.2 SFF8643 interface into four SFF8482 SAS/SATA ports, enabling mass storage expansion for servers, NAS units and workstations. Built with 30AWG low-loss copper conductors, it maintains stable 12Gbps data transmission across all four channels. The 1meter length supports tidy internal routing in dense chassis and rackmount systems. Plug-and-play operation simplifies integration with RAID controllers and storage backplanes.

Suited for RAID arrays and multi-drive deployments

Storage builders who need to connect multiple SAS or SATA drives to one M.2 SFF8643 port will find this cable purpose-built. The shielded harness reduces interference for reliable long-term operation in enterprise environments. Buyers who require more than four drive connections or a different host interface should look at alternative breakout solutions. The fixed 1meter length may not reach across larger enclosures without additional cable management.

12Gbps bandwidth over 30AWG copper

The critical specification is the sustained 12Gbps transfer rate delivered through 30AWG pure copper wiring. This bandwidth ceiling determines whether the cable can saturate modern SAS/SATA SSDs and HDDs in a four-drive configuration. Verify that your RAID controller and drives support 12Gbps operation to utilise the full capability of this interconnect.

Questions about this item

Does the 30AWG copper construction stay cool when the 12Gbps link runs continuously?

The 30AWG low-loss copper conductors are specified for stable 12Gbps transmission, keeping signal integrity and heat within normal limits for enterprise RAID workloads.

What controller or backplane must I already have to use the M.2 SFF8643 end?

You need a host with an M.2 SFF8643 port that exposes SAS/SATA lanes — typically a RAID controller, server motherboard or NAS appliance with that exact connector.

Will my existing SFF8482 SAS/SATA drives work on the four breakout ports?

Yes, each of the four SFF8482 connectors accepts standard SAS or SATA drives, so current SFF8482-attached HDDs or SSDs plug in directly.
