Someone missed an important part of the standard (JEDEC JESD218, section 6.3): "This standard is based on a use scenario in which the SSDs are actively used for some period of time during which the SSDs are written to their endurance ratings, followed by a power-down time period in which data must be retained."
E.g. in Intel's product spec for the DC S3500 series, the data retention parameter is specified as: "3 months power-off retention once SSD reaches rated write endurance at 40 °C".
