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，4Kn Corresponds to another TA Suffix variant；Do not mix variant specifications。 / This SKU is 512e; 4Kn uses a separate TA-suffix model. |
| 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. |
| Units and security variants | MiB/GiB Measured in binary units；This page is for Standard Part number，SIE/SED Is an option for other orderable part numbers。 / MiB/GiB are binary units. This is the Standard SKU; SIE/SED options use different ordering codes. |
