Abstract: Disclosed is an operating method of a storage device which includes a plurality of nonvolatile memory chips. The method includes providing, at the storage device, information of a capacity of each of the plurality of nonvolatile memory chips to an external host device, receiving, at the storage device, information of a plurality of groups from the external host device, performing a reset after receiving the information of the plurality of groups, mapping, at the storage device, the plurality of nonvolatile memory chips with the plurality of groups, and configuring the plurality of nonvolatile memory chips so as to correspond to the plurality of groups, after performing the reset.

Abstract: An method of a storage device configured to communicate with an external device through an interface channel includes: storing a throttling predefined table (PDT) including a relationship between target performances and workload characteristics; detecting that a first workload characteristic has changed; determining whether to update the PDT; when it is determined to update the PDT, monitoring a performance of the storage device; updating the PDT to include at least one new value for the workload characteristics and an additional target throttling performance value, based on a calculated monitored performance and the changed value of the first workload characteristic; controlling an operation parameter based on the updated PDT such that the interface channel has a first throttling performance corresponding to the additional target throttling performance value; receiving a first request through the interface channel from the external device; and processing the first I/O request through the interface channel.
