ASUS DGX Spark SSD Upgrade: Replace 1 TB1TB with 2 TB2TB and Reinstall DGX OS

Published 19/05/2026

Description

In this video, I upgrade my ASUS DGX Spark from a 1 TB1TB M.2 SSD to a 2 TB2TB M.2 SSD, then reinstall the official DGX OS from scratch. I show the full process: opening the device, replacing the internal 2242 NVMe SSD, downloading the ASUS / NVIDIA DGX OS image, creating a bootable USB installer, exploring the BIOS, and reinstalling Ubuntu-based DGX OS on the new drive.

Since this system only supports a single internal M.2 drive, upgrading the SSD means replacing the original disk and reinstalling the operating system. What you’ll learn in this video: Opening the ASUS DGX Spark chassis Identifying the internal 22422242 M.2 NVMe SSD Replacing the original 1 TB1TB drive with a 2 TB2TB SSD Looking at the internal design, cooling, fans, and heatsink Downloading the official ASUS DGX OS / NVIDIA DGX OS image Extracting the ISO from the downloaded archive Creating a bootable USB installer with Rufus Booting from USB and reviewing BIOS / UEFI settings Reinstalling DGX OS on the new SSD Verifying that the system detects the full 2 TB2TB capacity Updating the system after installation If you are using the DGX Spark as an AI workstation, developer box, inference node, or headless Linux machine, upgrading storage can make a big difference once models, containers, checkpoints, and datasets start piling up.
