Can you increase storage from 128 GB to 512 GB?

I am thinking about getting the 128 GB version of the early 2014 MacBook Air, and then upgrading the storage. It looks like the maximum amount of storage is 512 GB. This comes from the specs page at Apple, but the page is less then clear about this. Can anyone confirm that you can bump the 128 GB MacBook Air to 512 GB?

Apple will sell you a 512GB model, they do not offer an upgrade path from the 128GB model after you buy it.

The SSD Apple is using in this model is a custom M.2 PCIe unit which is only available from Apple currently.

OWC and others have shown there upgrade products but haven't started selling them. OWC is even planning on offering a larger size than what Apple offers! So hang tight as some options are coming soon.

If on the other hand you are planing on buy a system I would get the larger sized SSD model to start with.

"The SSD Apple is using in this model is a M.2 PCIe unit which is only available from Apple currently"

Is it a special type of M.2? Because you can buy numerous PCIe M.2/NGFF ssds on amazon


The M.2 standard defines the physical size and connector interface. The standard left open the interface dialog. The way the SSD is programed defines it's interface. Sadly, you just can't plug in anything and expect it to work.


Well, it took a little more time but here it is! OWC SSD Upgrades for MacBook Air 11" & 13" Mid 2013, 2014, and 2015


Dan i definetely feel like you miss Something there.

Why not a word on the adapters that make the custom port a classic M2 ?


Nope! Didn't. I'm not a fan.

We did some deep testing on a few adapters and SSD's a few years ago they may appear to work for someone without the needed test tools. They have issues!

If you review here on MacBook Pro Unibodies you'll see quite a few having HD SATA cable failures and you'll see people thinking I was on a booze bender ;-}

But after they replaced the cable their performance issues disappeared!

So what does that have to do with SSD's? Not much difference!

Keep in mind this systems SSD is a AHCI/PCIe 2.0 2 lane. AHCI error management is CRC so you won't see the quantity of errors which can create corruptions in the drive with these crappy adapters.

Don't drink the Kool-Aid

There are some sites selling used drives for this machine, but they are going to cost you a good amount.
