Once the P4800X has reached its write endurance rating, it is specified for unpowered data retention of 3 months, which is standard for enterprise SSD. Intel doesn't say anything directly about data retention when the drive is new, but the do caution that the drive will perform background data refreshing. When the drive is powered on, it will devote more time than usual to background data refreshing for a period of about three hours, to clean up any data degradation that may have occurred while the drive was off for an unknowable period of time.
Те же 3 месяца гарантируют.
