Statement: In RAID 2.0+ architecture, thick LUNs are composed of grains. Is this statement True or False?

Explanation:
Grain-based allocation is a feature of thin provisioning. In this approach, storage is allocated in small units called grains as data is written, allowing space to be used flexibly and growth to occur on demand. Thick provisioning, on the other hand, pre-allocates the entire LUN capacity up front and uses it as a single, large block of space rather than breaking it into grains. Therefore, saying that a thick LUN is composed of grains isn’t accurate. The statement is false because thick LUNs are fully allocated and not built from grain-sized units, while grains are the mechanism used to support thin provisioning.
