Questions about Logical Hierarchies in Storage Devices
How do logical hierarchies impact storage device performance?
Logical hierarchies help organize data in storage devices, improving access times and overall efficiency.
What are the key considerations when selecting a garbage collection operation mode?
The capacity of the free area and the amount of garbage data in the logical area are crucial factors in determining the appropriate operation mode.
Original Abstract Submitted
Logical hierarchies include an append hierarchy in a storage device. The storage device writes user data received in the append hierarchy to a free area, select a garbage collection operation mode for a first logical area in the append hierarchy from operation modes including first and second operation modes. Conditions of executing the garbage collection in the first operation mode include a capacity of the free area in the append hierarchy being less than a threshold, and an amount of garbage that is invalid data after update in the first logical area being equal to or greater than a threshold. Conditions of executing the garbage collection in the second operation mode include the amount of garbage in the first logical area being equal to or greater than a threshold value, while excluding the condition of the capacity of the free area in the append hierarchy.
