According to the product specialist

Pros
The heat dissipation of this brake disc is very good by Shimano's Ice-Technology Freeza.
Due to the harder material, this brake disc can also be used with Semi-Metallic and metallic brake pads.
This brake disc is made of light materials and therefore has a low weight.
You can choose different sizes of locking rings with this brake disc, so you don't have to buy extra lock rings with a 15 mm through-axle.
These brake discs deform relatively little when heated, and are therefore less likely to seize.
Outstanding braking power in all conditions.
Excellent heat dissipation, which greatly improves braking power.
Super lightweight!
Less affected by crosswinds thanks to the open design.
These brake disc rotors have solid and reliable braking performance.
Durable brake discs made of hardened steel.
Mud or dirt is easily drained thanks to its open structure.
Cons
This brake disc is slightly heavier than the XTR MT-900 brake disc.
