4. Upgrading the Storage

– The laptop is fitted with a single M.2 slot compatible with both 2230 and 2280-sized Gen 4 SSDs.
– The pre-installed SSD on our device is a shorter NVMe variant, protected by a metal shroud featuring a thin thermal pad on its inner surface.
Note: Although the slot is built for Gen 4 SSDs, it operates at Gen 3 speeds.
