A short SFF-8644 to SFF-8643 SAS cable with black connectors and thin round wire

Vszerda

Vszerda Mini SAS HD Cable SFF-8644 to SFF-8643 12Gbps 28AWG 0.5m

SKU CH-3FH6-3FXMZ

Connects SFF-8644 to SFF-8643 at 12Gbps using 28AWG copper wire for server and storage arrays

  • 12 Gbps single-channel speed for high-bandwidth server links
  • 28 AWG oxygen-free copper reduces signal loss over distance
  • SFF-8644 to SFF-8643 connectors fit SAS host-to-drive links
  • 100 % open-short tested with 300 V withstand for reliability
  • Half-metre length suits tight rack and enclosure routing

Server interconnect cable

The Vszerda Mini SAS HD cable connects SFF-8644 and SFF-8643 interfaces for 12Gbps single-channel transmission in servers, RAID cards and storage arrays. It targets administrators who need a short, high-bandwidth link between compatible controllers and backplanes.

Build quality and daily use

Oxygen-free 28AWG copper conductors keep signal loss low, while 100% open and short testing plus DC 300V .01s withstand voltage and 10M insulation resistance confirm reliable electrical properties. The .5 metre length suits tight rack spacing and reduces cable clutter during routine maintenance.

Upgrade context

This cable replaces older SAS interconnects limited to lower signalling rates when the controller and backplane both support 12Gbps operation. The jump is worth it only if the existing link is a proven bottleneck and both ends present SFF-8644 and SFF-8643 ports.

Questions about this item

What data rate does the SFF-8644 to SFF-8643 cable support?

The cable supports up to 12Gbps single-channel transmission for high-bandwidth server and storage links.

What physical clearance does the 28AWG copper cable need for routing?

The 28AWG oxygen-free copper wire is thin and flexible, suited to tight server chassis and dense storage-array routing.

How is the SFF-8644 to SFF-8643 cable installed, and what step is often missed?

Push each connector straight in until the latch clicks; the common mistake is stopping before the latch fully engages, leaving the link unseated.
