> But in a real world usage scenario where we subject a consumer SSD and an enterprise SSD to the same number of P/E cycles, would they have different data retention? Probably not, assuming they're using the same underlying media and same strength of ECC and that the amount of host data written was appropriately adjusted to account for the different capacities and overprovisioning ratios to ensure the actual P/E cycles seen by the NAND were the same. As you write more data, the consumer drive would be out of warranty first, while the enterprise drive would still be under warranty but not spec'd to retain data for as long as the worn-out consumer drive. So for either drive, the manufacturer isn't guaranteeing 1 year retention past the rated endurance of the consumer drive.
