1. Suffix code variation (AAA0 vs. ABA0): This typically indicates an internal revision or production lot update. The ABA0 version likely incorporates improved NAND flash die or a revised controller solution, which may enhance long‑term write stability or power efficiency. These changes could particularly affect endurance in pSLC mode. 2. Price differential: The ABA0 carries a notably higher price, suggesting it may undergo additional screening or testing for industrial or high‑reliability applications—such as extended life validation or stricter environmental compliance. The AAA0 is likely a standard commercial‑grade component. Note: Both devices share identical core specifications (capacity, speed, technology, temperature range) and are functionally compatible at a basic level. The ABA0, however, may include unannounced reliability enhancements.
