Using Apple’s new ARM-based PC processor Apple M1, MacBook Air draws attention with its SSD speeds. Reports show it offers twice the data rate than the Intel-based version.
The 2020 MacBook Air has been criticized by users for having low SSD speeds. Keeping these criticisms in mind, the company made a number of changes to the new M1 processor version. Accordingly, the new version includes an advanced controller in the special 5nm M1 chip as well as a faster SSD.
A MacRumors member with the username Abbotsford1980 tested the SSD of the M1 MacBook Air and achieved impressive results by comparing them with the 2019 and 2020 MacBook Air models using an Intel CPU. The surprising thing about the previous generation Intel versions was that the version released in 2018 had a faster SSD than its successors.
According to the test results, the M1 MacBook Air achieves 2676 MB / s and 2190 MB / s read and write speeds, respectively. Apple mentioned that the new storage controller will help with improved SSD speeds when introducing the M1 Mac models. You can also see the results in the photo below. It should also be noted that these tests were conducted with the version with 256 GB SSD. In this case, it may be possible for versions with higher capacity SSD to reach higher speeds.
Finally, let’s point out that the default model M1 MacBook Air can be ordered with 256 GB SSD, and you cannot replace the 256 GB SSD yourself later, so if you want a higher SSD, you need to configure the model when ordering.
