Two SFF-8643 Mini-SAS HD cables fanning out to four SATA connectors each, 3.3 ft length

V2 Technologies

V2 Technologies 2Pack SFF-8643 to SATA 1M 3.3FT 2 in 1 accessory

SKU CH-KHD9-MH3KM

Two cables split one SFF-8643 Mini-SAS HD port into four SATA drives at up to 6 Gbps each

  • Connect 4 SATA drives per port via SFF-8643 Mini SAS HD
  • 6 Gb/s per drive for fast storage throughput
  • Locking latch on SFF-8643 ensures secure internal connection
  • 1 m cable length suits compact chassis builds
  • Labeled breakout ends simplify cable management in dense arrays

Two-pack SFF-8643 to SATA breakout cables

This two-pack provides SFF-8643 Mini-SAS HD to SATA forward breakout cables. Each cable connects a single SFF-8643 male port on a SAS RAID controller or motherboard to four SATA drives or a backplane. The set suits builders adding SATA storage to a high-density SAS host interface. It is not for users who need a reverse breakout or direct backplane-to-backplane links.

Thermals noise and power draw

Passive cable assemblies generate no heat and produce no audible noise. They draw no auxiliary power beyond the signal lines supplied by the host controller. The thin, tape-and-braid weave construction keeps airflow unimpeded inside the chassis. No active cooling or extra power budget is required.

6 Gbps per drive data rate

Each SATA lane operates at up to 6 Gbps, matching the SATA 6 Gbps specification. The SFF-8643 host connector is rated for 12 Gbps SAS, but the breakout limits each attached drive to the SATA ceiling. This rate decides whether the cables meet the throughput needs of the target drives.

Highlights

  • Connect 4 SATA drives per port via SFF-8643 Mini SAS HD
  • 6 Gb/s per drive for fast storage throughput
  • Locking latch on SFF-8643 ensures secure internal connection
  • 1 m cable length suits compact chassis builds
  • Labeled breakout ends simplify cable management in dense arrays

Questions about this item

How do I install the SFF-8643 to SATA breakout cable, and what is the common mistake?

Plug the SFF-8643 male end into the SAS RAID controller or motherboard port, then attach the four SATA connectors to drives. The mistake is connecting the SFF-8643 side to a backplane instead of the controller.

What maintenance or replacement will the cable need later?

Inspect the locking latch and braided sleeve periodically; replace the cable if the latch no longer clicks or if the weave shows fraying that could affect signal integrity.

What limit appears first under sustained use?

Each SATA drive is capped at 6Gbs data transfer, so that per-drive ceiling is reached before the 12Gbps controller link becomes a bottleneck.
