80CM SAS 4.0 PCIe Slimline LP Low Profile SFF-8654 8i 74Pin to SFF-8643 8i 36Pin Server Storage Adapter Cable, High Speed Mini SAS HD Internal Data Cord for RAID Controller & Hard Drive Backplane

This 80-centimeter Slimline SAS 4.0 high-speed adapter cable adopts low-profile LP SFF-8654 8i (74Pin) male to SFF-8643 8i HD Mini SAS 36Pin male interface conversion design, fully compliant with SAS 4.0 and PCIe 4.0 transmission protocols, supporting maximum 24Gbps single-channel bandwidth to meet the ultra-high-speed data transmission requirements of enterprise-level storage servers, workstations and NAS disk arrays.

The SFF-8654 low-profile slim connector greatly reduces the occupied height of the PCIe expansion slot, solving the installation obstacle of dense half-height server motherboards and narrow cabinet interiors. Both ends use thickened gold-plated elastic contacts to effectively avoid poor contact, hard drive dropout and transmission errors caused by long-term vibration and high-temperature working environment inside the chassis.

The whole wire harness is wrapped by dense black braided protective sleeve, which has excellent anti-electromagnetic interference performance, blocks signal crosstalk from power modules and other hardware, and maintains complete signal integrity during continuous heavy-load reading and writing of multiple HDD and SSD hard disks. The internal high-purity copper conductors have precise impedance control, stable line loss and strong bending resistance, conforming to industrial RoHS safety standards.

It is widely used for connecting Slim SAS HBA RAID array cards, motherboard onboard Slimline SAS ports to hard drive backplanes, storage expansion cages and JBOD storage enclosures, an essential internal wiring accessory for data center equipment renovation, server storage capacity expansion and high-performance computing hardware deployment.
