Servo Wave
When you pull a Servo Wave brake lever initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.

I-Spec is technology that integrates the shifters and brake levers offering a clean handlebar setup.
Note: I-Spec went through an update in 2014 now known as I-Spec (Version B). Older I-Spec technology is not compatible with the new but with the help of an adaptor this problem can be solved: ( SM-SL98-B for XTR, SM-SL78-B for XT and SLX, SM-SL82-B for Saint). I-Spec II and I-Spec EV are not compatible with I-Spec B.

One Way Bleeding
One Way Bleeding was developed for quick and easy prevention of air in Shimano’s hydraulic system. Shimano has streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

The fade, which can occur to rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technology rotors and Ice Technology pads to realize the cooling technology for consistent performance. The rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400 °C to 300°C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the rotor blade and the radiator fin provide long pad life, less noise, less fade and are lightweight.
XTR, Saint, Deore XT, SLX, Zee, Deore LX calipers are bundled with Ice Technology pistons in order to achieve optimized lightweight, high rigidity and heat dissipation. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss.

I love these. Both the operation of the brake as well as the short, comfortable handles.

I have now compared the Saint M820 to a set of Hope Tech 3 V4 which is another contender for the title of the best DH brakes in the world. Test bikes where a 18.5kg Mondraker Summum 2013 downhill bike and a 13.5kg Mondraker Foxy 2011 trail bike.
Saint M820:
+ Stronger
+ One finger is enough for full brake power.
+ Stops the bike faster
- The window where you have 80-100% and 50-70% brake power is small and takes practise.
- Less good in turns, as a small mistake will cause a locked front wheel.
Hope Tech 3 V4:
+ Almost as strong as the Saint M820. It will reach full stop, it just takes a bit more effort.
+ Less chance to panic brake and lock the front wheel in turns.
+ Many degrees of braking power, I can choose between 35 and 45% braking power easily.
- Needs two fingers and sometimes three fingers to make full stop from high speed.
I ended up using Hope Tech 3 V4 on the Summum downhill bike and the Saint M820 on the Foxy trail bike. My riding on downhill tracks is a bit more dangerous and I don't want to risk to lock the front wheel and break my back on some rocks.
