Description
Technical Field

[0002] The RDT (Reliability Demonstration Testing) test is a reliability and durability test for solid-state drives (SSDs). The principle is to pre-open the card and burn the RDT self-running program. Then, the solid-state drive is placed in a temperature-controlled environment and powered on. The RDT self-running program erases, writes, saves, and reads each storage block of the flash memory chip, and generates test data. Finally, the card is opened a second time to identify and isolate bad blocks. The RDT test is a mandatory test item for solid-state drives.
