SMUGDESK SFF-8643 to 4 SFF-8482 Mini SAS HD cable 12Gbps 15pin power 29pin
An internal cable splitting one SFF-8643 Mini SAS HD port into four SFF-8482 connectors with integrated 15pin power for direct 2.5" or 3.5" SAS and SATA drive attachment at up to 12Gbps
- Splits one SFF-8643 port into four independent SFF-8482 connectors for multi-drive expansion
- Delivers up to 12Gbps transfer rate for stable SAS and SATA drive performance
- Integrated 15pin power port supplies drive power directly without extra cables
- Standard 29pin SFF-8482 terminals ensure compatibility with enterprise HDD and SSD
- High-shielded construction reduces signal interference for reliable long-term server operation
Connection layout
This SMUGDESK cable splits a single SFF-8643 Mini SAS HD port into four independent SFF-8482 connectors. Each connector carries both data and a 15pin SAS power interface, eliminating the need for separate power cables. The assembly supports up to 12Gbps transfer rates for SAS and SATA hard drives. Shielded construction maintains signal integrity inside server chassis.
Server storage builders
The cable suits administrators expanding internal storage on RAID controllers or backplanes that present an SFF-8643 interface. It connects directly to 2.5in and 3.5in enterprise SAS or SATA drives without extra wiring. Builders who need more than four drive connections must choose a different solution. Systems requiring a different host connector or drive interface are not compatible.
Single specification check
Verify that your RAID controller or backplane provides an SFF-8643 Mini SAS HD 29pin port and that your target drives use SFF-8482 connectors. The integrated 15pin power delivery works only with drives designed for SAS-powered backplanes. Matching these two interface types confirms the cable will fit your server storage expansion.

Questions about this item
How do I plug the SFF-8643 end into my RAID controller and avoid the common mistake of leaving the 15pin power port disconnected?
Insert the SFF-8643 Mini SAS HD connector firmly into the controller port until it clicks, then attach a standard SAS 15pin power cable to the built-in power port so each of the four SFF-8482 drives receives both data and power.
What upkeep will the four SFF-8482 connectors and the integrated 15pin power interface need over time?
Inspect the latch tabs on each SFF-8482 plug and the 15pin power socket during routine server maintenance; reseat any connector that feels loose and replace the cable if pins show corrosion or the shielding braid is frayed.
At what point does the 12Gbps link become the bottleneck during sustained heavy I/O to multiple 2.5 or 3.5 SATA drives?
The single SFF-8643 uplink caps aggregate throughput at 12Gbps, so continuous sequential workloads spread across all four drives will hit that ceiling before individual drive limits are reached.
