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 | This part number is 512e，Verify the exact part number when ordering，Do not assume convertibility 4Kn。 / This SKU is 512e; verify the exact part and do not assume 4Kn conversion. |
| 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. |
| Reliability conditions | Manufacturer MTBF Conditions include 40°C、220TB/year；Higher workload or temperature affects applicability of the metric。 / Vendor MTBF conditions include 40°C and 220TB/year; higher workloads or temperatures affect applicability. |
