EXCELLENT CONDUCTION PERFORMANCE: The seven contacts are gold plated with pure copper, wear resistant and anti corrosive, enhancing the quality of signal transmission and longer service life. DUAL CHANNEL: Mini SAS SFF to 47Pin data cable uses a dual channel aluminum foil cable for faster and more efficient data transfer, and a slim, flexible, pull resistant cable that can be flexibly placed in any corner. TINNED COPPER CORE: Mini SAS SFF to 47Pin cable uses thicker and higher purity tinned copper core with aluminum foilto greatly improve data transfer efficiency and speed, while reducing heat loss. FAST TRANSFER SPEED: SAS connectors allow devices to be connected via cable or directly to the backplane. Data transfer speeds of up to 12GBPS can be achieved. SAS CONNECTION SYSTEM: SAS is a point to point connection storage system, which is a smaller, more resilient serial design connection system that replaces SCSI.
