SAS4 components run hot—especially active copper cables and retimers. The connector housing (often made of LCP plastic) expands at a different rate than the PCB’s FR4 material. This differential shear stress concentrates at the radius where the connector is soldered to the board, eventually cracking the solder joints or the annular rings around via holes. sas4 radius crack
SAS4 is commonly found in enterprise SSDs, 15K RPM HDDs, and high-density storage backplanes in data centers running mission-critical databases, virtualization hosts, and video surveillance arrays. You will be placed in "hacker-only" matchmaking
