Summary:The invention discloses a trim data verification test method, device and system for an SSD (Solid State Disk), and the method comprises: building a trim table which comprises a plurality of recordingbits, enabling the number of the recording bits to be the same as the number of logic block addresses of the SSD to be tested, and enabling one recording bit to correspond to one logic block address;when a trim command is issued to the SSD (Solid State Disk) to be tested, setting a corresponding record bit in the trim table as an invalid identifier; when a write command is issued to the SSD (Solid State Disk) to be tested, setting a corresponding record bit in the trim table as an effective identifier; and after delivery of all commands is completed, reading the data content of each logic block address of the SSD (Solid State Disk) to be tested, verifying the identification information of each corresponding record bit in the trim table, and if the data content of all logic block addressesis consistent with the ide
