Feature: 1. 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. 2. 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. 3. TINNED COPPER CORE: Mini SAS SFF to 4 SATA 7Pin cable uses thicker and higher purity tinned copper core with aluminum foil shield to greatly improve data transfer efficiency and speed, while reducing heat loss. 4. DUAL CHANNEL: Mini SAS SFF to 4 SATA 7Pin 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. 5. 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.
