1. An error generating apparatus of a solid state drive tester, the error generating apparatus comprising: a host terminal for receiving a test condition for a test of a storage from a user; and a test control unit for creating a test pattern according to the test condition or creating a test pattern randomly, generating error data used to test an error characteristic of the storage, and testing the storage based on the test pattern and a specific instruction or an error instruction formed by inserting the error data into the specific instruction, wherein the test control unit comprises: an embedded processor for controlling the test of the storage and insertion of the error data; an error generator for generating the error data to test the error characteristic of the storage; and a test executing unit for generating the test pattern to test the storage according to a control of the embedded processor, transmitting the specific instruction generated from the embedded processor or the error instruction formed by inserting the error data into the specific instruction to the storage, reading out a test pattern from the storage, and comparing the stored test pattern with the generated test pattern in real time to process a test failure state.
