The SKU:HUH721212AL4200 is a part number referring to an Enterprise-Class Hard Disk Drive (HDD) from the HGST/Western Digital Ultrastar DC HC520 (He12) series.
This is a high-capacity, high-performance drive primarily used in data centers, cloud storage, and enterprise server environments.
Again these drives are SAS , meaning they are only compatible with enterprise-class systems (servers, storage arrays, etc.) that have a SAS controller and drive backplane.
Since they are 4Kn (4K Native) drive, older RAID controllers or operating systems might not fully support its advanced sector format. You must verify that your host system's hardware and software are compatible with 4Kn drives.
The drive has been noted to be supported in Dell server models such as:
- ::Dell PowerEdge: R740, R740XD, T640, T440, etc. (Generally 14th Generation and newer)
- ::Dell Storage: NX series

Please note:-
If you intend purchasing this drive for a specific server, you should ensure the drive is either a bare drive (if you have a compatible caddy) or comes pre-mounted in the correct manufacturer's hot-swap caddy (e.g., a Dell tray).
