This M.2 NGFF SATA adapter card is the ideal upgrade solution for owners of Apple's 2012 Air models, including A1466, A1465, MD223, MD224, MD231, and MD232, seeking to enhance their device's performance. Crafted with precision, it's designed specifically to accommodate M.2 NGFF form-factor SSDs that use the SATA protocol. Importantly, this adapter does not support PCIE X2 or X4 transfer protocols, so it's crucial to select an SSD with a single-sided component layout to ensure a proper fit within your MacBook Air's limited space.
