SSD Upgrade Guide for the Microsoft Surface Laptop 3 15
This device uses a M.2 2230 drive with a NVMe PCIe 3.0 interface. Maximum supported capacity is 1TB.
NVMe drives are significantly faster than SATA — if your device supports NVMe, always prefer it over a SATA SSD for the best performance.
Always power off your device and disconnect power before replacing storage.
