Fledging took flight in 2018 on a mission to bring premium electronics to everyone, starting with SSD storage. In 2018, our founder was in the middle of a PhD program when his Mac started dying. His only choices were to sacrifice his Apple experience or spend a ton of money on a newer device. Instead, he invented a premium Mac SSD upgrade, and Feather SSD was born. 


The MacBook Air 13” A1466 series offers reduced weight, a user-friendly 13” screen, and a great price - so we built our Feather M12 product line. In this article, we’ll explain the three main benefits of upgrading your A1466 with Feather M12 by Fledging and how you can buy Feather M12 for your MacBook Air.


First, Feather M12 is a true SSD upgrade for your MacBook Air. Like Apple, we've maxed the sequential speeds of the SATA III form factor at 400MB/s Read and Write. But unlike Apple, our SSDs store up to 1 terabyte of data. That’s up to 4 times as much storage as the OEM SSD that came with your MacBook Air. And with a newer SSD, your MacBook Air will perform like new (or better!)


Second, Feather M12 is built to be affordable. By building our own SSD adapter from scratch and partnering with the best-performing and most stable SSD manufacturers, we’re able to sell this SSD upgrade for less than our competition, while giving you better results. Why? That’s Fledging’s mission - “premium electronics for everyone” means “everyone should be able to afford our products”. Feather is typically 10-20% less expensive that other SSDs that perform about as well, while notably outperforming SSDs that are less expensive.


Third, true DIY with everything you need to upgrade your MacBook Air ships with Feather M12. 

  • We pre-load macOS High Sierra, though you can upgrade to a new OS once installed
  • Feather ships with the tools needed to remove your MacBook Air’s back panel and the SSD mounting screw
  • A detailed instructions booklet ships in every package
  • You can contact us online, at our FAQ, or by emailing [email protected] to connect with Laura, our Customer Success Manager (and real, live human).
  • Upgrading your Apple MacBook Air's solid state drive SSD involves a lot of moving parts. We're worked hard to simplify all that for you
