M2/M3 MacBook Air vs Intel MacBook Air: Soldered storage means no SSD upgrade ever

The M2 and M3 MacBook Airs solder storage to the motherboard — no slot, no connector, no upgrade path. Old Intel Airs had removable SSDs, but these M-series chips use a custom controller baked into the board. Apple’s upgrade prices are brutal, and third-party repairs are unlikely. Your only workaround is external storage via Thunderbolt or USB-C. Buy what you need upfront.
