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. Speeds are sustained up-to ratings; CM7 performance is single-port (1×4) mode. Security options are region-dependent. FIPS SED means a module designed to comply with FIPS 140-3; current validation status must be obtained from KIOXIA, not assumed.
