Have you ever wondered where defective NAND chips or those that don't pass the requirements go? Not inside the best SSDs, that's for sure. However, you'll likely find them inside knock-off SSD brands that sell for ridiculously low prices on platforms like AliExpress.
NAND yield rates are typically bad until the process node matures. Often, factories come across NAND that doesn't meet the client's requirements or doesn't pass quality control. Instead of throwing the NAND away, which increases electronic waste, the factories recycle them into cheaper products or sell them to local companies, giving rise to obscure SSD brands on the Chinese market.
