SMUGDESK Mini SAS HD Cable with IC SFF8644 to SFF8643 12Gbps 28AWG 1m

SKU CH-8XRN-YM3E5

Connects external SFF8644 to internal SFF8643 with built-in IC for stable 12Gbps SAS and SATA storage expansion

  • Built-in IC chip stabilizes signal transmission for long-distance server connections
  • Converts external SFF8644 to internal SFF8643 for flexible storage expansion
  • 28AWG low-loss copper wire delivers stable 12Gbps bandwidth for SAS and SATA drives
  • 1 meter length supports tidy routing in rackmount servers and JBOD enclosures
  • Robust anti-interference shielding ensures reliable long-term performance for RAID and enterprise storage

External-to-internal SAS bridge

This cable connects an external SFF8644 port to an internal SFF8643 Mini SAS HD interface, enabling storage expansion between servers and JBOD enclosures. An integrated IC chip stabilises signal transmission over the one-metre run, making it suitable for data-centre and enterprise workstation deployments.

Sustained 12Gbps throughput

Premium 28AWG low-loss copper conductors and robust anti-interference shielding maintain steady 12Gbps bandwidth under continuous RAID and heavy I/O workloads. The built-in IC minimises attenuation so performance does not degrade during long-duration transfers across SAS and SATA drives.

Replaces passive direct-attach cables

When a passive cable cannot reach between chassis or introduces errors at full speed, this active IC-equipped link provides the necessary signal integrity. The jump is worth it for rack-to-rack or backplane-to-HBA runs where distance or electromagnetic noise would otherwise limit reliability.

Questions about this item

Does the built-in IC chip on this SFF8644-to-SFF8643 cable add noticeable heat or power draw inside a server running all day?

The integrated IC is passive and draws negligible power; it generates no measurable heat during continuous 12Gbps operation.

What connectors must my server and storage enclosure already have for this 1m SFF8644-to-SFF8643 cable to plug in directly?

One end needs an external SFF8644 Mini SAS HD port and the other an internal SFF8643 Mini SAS HD port; no adapters are included.

Will this 12Gbps SFF8644-to-SFF8643 cable work with older 6Gbps SAS or SATA drives in my existing backplane?

Yes, the 12Gbps link is backward compatible and will negotiate down to 6Gbps for legacy SAS or SATA drives.
