We study the supersymmetric standard model in a slice of five-dimensional AdS, where supersymmetry is broken by imposing different boundary conditions between the fermions and bosons of bulk superfields. The scale of supersymmetry breaking is exponentially small due to the warp factor of the AdS metric, and is transmitted through the AdS bulk to matter fields confined on the Planck-brane. This leads to a predictable superparticle mass spectrum where the gravitino mass is 10^<-3>eV, and scalar particles receive masses at the one-loop level via bulk gauge interactions. Furthermore, the AdS/CFT correspondence suggests that the 5d warped model is dual to the ordinary 4d MSSM with a strongly coupled CFT sector responsible for the breaking of supersymmetry.
