Selection, Compatibility and Limits
| Host compatibility | Check the server/Workstation、RAID/HBA、Backplane、Firmware、Capacity and sector format；Specifications are not whole-system compatibility certification。 / Validate host, RAID/HBA, backplane, firmware, capacity and sector format; specifications are not system qualification. |
|---|---|
| Sector format | Default 512e；Conversion 4Kn First verify platform support and create a full backup，Format conversion may erase data。 / Default 512e; confirm support and back up before 4Kn conversion, which may erase data. |
| Power and installation | Check 3.5 Inches Drive bays、Drive tray、SATA Interface、Power-on power margin and airflow；Hot-swap capability depends on the host system。 / Check 3.5-inch bay, carrier, SATA connection, PSU spin-up headroom and cooling. Hot-swap depends on the host system. |
| Usable capacity and backup | Nominal TB Is decimal capacity，Formatting and the file system reduce usable capacity；RAID Does not replace an independent backup。 / TB is decimal capacity; formatting and filesystems reduce usable space. RAID is not a substitute for independent backup. |
| Statistical reliability | MTBF/MTTF And AFR Are population-level statistical metrics under manufacturer-specified conditions，Not an individual-drive lifetime or zero-failure guarantee。 / MTBF/MTTF and AFR are population statistics under vendor conditions, not individual drive-life or zero-failure guarantees. |
| Capacity-specific source priority | Weight and power use the applicable capacity's Exos X24 SATA Product Manual Rev C（2023-11），Power consumption Table 7；Where it differs from the family datasheet, this page follows the manual's table。 / Weight and power follow the exact-capacity columns and Table 7 in the November 2023 Rev C SATA manual rather than shared datasheet figures. |
