According to the test, the storage speed of the Apple MacBook Air M2 is poor

Tech Highlights:

  • Going by the results we’re seeing in Blackmagic’s Disk Speed Test app, the base model of the M2 MacBook Air has write speeds that are generally 15 to 30 percent slower than those of the 512GB model Apple sent The Verge to review — and read speeds that can be 40 to 50 percent slower. This is not an unexpected result since the base Air only includes a single NAND chip, while the M1 models and 512GB (and up) M2 models have two, which can allow for nearly twice as fast speeds.

  • A tabletop M2 MacBook Air with a purple marbled background and the About This Mac window visible. Previous reviews have noted that the arrangement of the storage models in Apple’s entry-level M2 MacBook Pro makes the SSD much slower than that of the M1 MacBook Pro. We’ve been wondering if the standard M2 MacBook Air might experience the same problem because Apple told The Verge that it has the same storage configuration as the Pro. We finally have a base model in our possession, which has 256GB of storage and 8GB of memory, therefore the answer is: yes, it does.

While I wouldn’t go so far as to say the speeds we’re seeing from this base MacBook Air are bad, they are (especially when it comes to reading data) the kind of speeds you can easily get on laptops that are a bit more, well, meh. For example, the base model is only a bit faster than my 2019 Intel MacBook Pro when it comes to write speeds, and its read speeds are significantly worse. To pick a Windows machine out of a hat, Microsoft’s Surface Laptop Go 2 (which starts at $600) also loses to the base Air on write but demolishes it on read. (Read speeds are generally more important for general usage, measuring how fast your device can access files on its system.)

That said, will these particular differences impact you? People the Air is marketed to will likely not see a life-changing contrast between the 256GB and 512GB models when it comes to everyday performance. I ran two 4K YouTube videos over 25 open Chrome tabs for 30 minutes on both machines without either needing to dip into swap memory. Boot time was also pretty identical — I turned the two devices on side by side a number of times. And I didn’t see much of a difference when it came to opening any of the apps I normally use, including Chrome, Safari, Messages, Photos, Activity Monitor, Slack, Music, etc.

We didn’t have an M1 Air with 256GB to test, but the 512GB model we do have on hand is also faster than the base M2 model on both read and write, as you can see in the results below. A screenshot of Blackmagic Disk Speed Test indicating scores of 2514.7 for Write and 3051.2 for Read. As Verge editor Dan Seifert explains in his review of the M2 Air, slower storage speeds can impact a number of tasks, including file transfers, and can also slow down overall performance since Macs use SSD space as temporary memory (swap memory) when their onboard RAM is used up.

For the MacBook Pro’s target audience, though, a limitation like this could be a deal-breaker. If you’re someone with a heavier workload (who very well may notice a difference), we generally recommend that you buy a MacBook Pro with an M1 Pro or Max chip instead of an Air. That said, these results certainly will matter to some people. If you’re in that camp, you’ll need to pay $200 to upgrade from 256GB to 512GB, bringing the eight-core M2 MacBook Air’s price from $1,199 to $1,399. If that seems like a lot, you can also get 512GB of storage and 8GB of RAM in the still-excellent M1 MacBook Air for $1,199 (the same price as the base M2 Air). My real-world comparisons have found that M2 machines are visibly better for graphics-heavy use cases (such as running games) but that their performance differences are not hugely impactful in other tasks (photo and audio editing, internet work, etc.) that a casual user might do.

We’ve reached out to Apple for comment on these specific results and haven’t received a response yet. When we asked the company about the different storage configurations for our review of the device, spokesperson Michelle Del Rio provided the following statement:

We will be happy to hear your thoughts
