Documented selection limits

Confirm exact host/backplane, SATA versus NVMe protocol, physical dimensions, firmware, capacity support and required security mode. Security variants can be region-restricted. No stock, lifecycle or universal compatibility promise. Endurance depends on the specified workload; MTBF/MTTF is a population statistic, not a drive-life guarantee. Up-to sustained full-LBA FIO 2.7, Linux CentOS7 kernel 5.3.1, queue depth 32 by 4 workers; 4KB random tests. Actual performance depends on system and workload. Warranty time and TBW are alternative limits, not cumulative guarantees; exact regional terms require confirmation.
