Request for Confirmation of AES-256 Hardware Encryption on DGX Spark NVMe SSD

Hi,

My DGX Spark has a Samsung PM9E1 4 TB NVMe SSD:

Model: MZALC4T0HBL1-00B07
Firmware: NXHB202Q

NVIDIA documentation states that DGX Spark storage is self-encrypting.

Can anyone confirm whether this specific SSD supports hardware-based AES-256 or AES-XTS-256 encryption?

If there is an official NVIDIA or Samsung document confirming this, please share the reference.

Thanks.

Yes — for the Samsung PM9E1 4 TB NVMe used in DGX Spark (MZALC4T0HBL1-00B07), we can confirm support for hardware-based AES-XTS 256-bit encryption and TCG Opal 2.0 self-encrypting-drive functionality.

For general DGX Spark references, the public documentation describes the storage as self-encrypting and documents the UEFI path for TCG Storage Security configuration (Hardware Overview, Security Tab / TCG Storage Security Configuration).

Thanks.
