Hello chan j,
Thank you for reaching out to the Microsoft Community! Thanks for sharing the details, I know how important it is to have enough storage, especially when you're working on engineering projects or managing large files. The good news is that yes, your Surface Laptop Go (Model 1943) does support SSD upgrades. The SSD in your device is removable and user-replaceable, though Microsoft classifies it as a “serviceable” part, meaning it’s not as easily accessible as in some other laptops.
It uses a M.2 2230 NVMe PCIe SSD, which is a compact form factor specifically designed for thin devices like the Surface Laptop Go. You can upgrade from your current 128 GB to 256 GB, 512 GB, or even 1 TB, as long as the replacement drive matches the 2230 size and NVMe interface. However, please note that replacing the SSD requires careful disassembly, including removing the keyboard deck, and may void your warranty if not done by a certified technician.
Once the new SSD is installed, you’ll need to reinstall Windows or clone your existing drive using an external enclosure. If you’d like help choosing a compatible SSD
