The Disc 28 XTR 2011+ Disc Brake pads are high performance brake pads from SwissStop. They fit a large range of brakes and are available in different compounds:
The Disc RS is an organic compound with balanced characteristics. It is highly durable and has predictable, progressive brake power in all conditions. This gives the rider a smoother feel in the the brake lever, and a quieter ride. The downside is they have less tolerance for heat, so shouldn't be used for gravity type riding.
The Sintered - Metallic compound offers improved braking in dry and wet conditions. It has very low pad wear and high heat resistance. It is perfect for gravity style riding. 
The Disc E Endurance compound was designed specifically with heavier E-bikes in mind. Its a long lasting compound that is able to withstand high temperatures from consistent heavy braking. It offers excellent modulation and is low noise and rotor friendly. It is also a great choice for heavier DH bikes. 
The EXOTherm 2 Compound can be described simply as Maximum Pad life with minimum brake fade. It combines a smooth modulating pad compound with a cooling finned back plate for consistent powerful braking in all conditions. 
The Resin-Organic compound is a high performance compound made from a Kevlar, Ceramic, Brass, and resin composite material. It is designed for maximum braking power with less effort required at the brake lever. The performance is great in both wet and dry conditions and they have excellent pad life.
