1. A data storage system, comprising:
a data storage device; and
a host device, coupled to the data storage device, to determine a margin of a parameter utilized by at least one transmission interface of the data storage device and the host device, wherein the host device performs a plurality of operations comprising:
(A) issuing a first command to set a value of a first parameter utilized by the host device to a first test value, wherein the first test value is selected from a first group comprising a plurality of setting values associated with the first parameter;
(B) issuing a second command to set a value of a second parameter utilized by the data storage device to a second test value, wherein the second test value is selected from a second group comprising a plurality of setting values associated with the second parameter;
(C) controlling the data storage device to perform a predetermined testing procedure to test whether the data storage device functions normally when the first test value and the second test value are applied; and
(D) changing the first test value according to the setting values comprised in the first group or changing the second test value according to the setting values comprised in the second group and re-performing operations (A) to (C), wherein operation (D) is repeatedly performed until all the test values in the first group and the second group have been tested.
