The 13-inch Macbook Pro with the M2 processor, recently introduced by Apple, has finally started to reach stores and customers abroad. Although Apple’s new processor M2 offers a performance increase compared to devices with M1 processors, it turned out that the same is not the case on the storage side.
According to tests shared by multiple YouTube channels, the M2 MacBook Pro, which offers 256GB of storage, has a slower SSD compared to the previous-generation MacBook Pro with the M1 processor.
M2 Macbook Pro lagged behind on storage
As a result of the comparisons made with Blackmagic Disk Speed Test, the first application that comes to mind for disk read / write performance, it was revealed that the Macbook Pro with M2 processor was 34 percent slower in writing performance and up to 50 percent slower in read performance.
To express this situation in numbers, one of the test results is as follows;
- M1 MacBook Pro: 2900 MB/s (read speed) and 2215 MB/s (write speed)
- M2 MacBook Pro: 1446 MB/s (read speed) and 1463 MB/s (write speed)
It is claimed that this slowness in SSD speed is specific to the starter model only. In tests with the M2 Macbook Pro with 512 GB of storage, very similar results were obtained to the model with the M1 processor. In other words, when you pay more money, this performance loss on the storage side disappears.
Why is the 256GB M2 MacBook Pro slower?
The YouTube channel Created Tech removed the bottom cover of the M2 Macbook Pro to understand the issue in more detail and realized that Apple had made some changes to the SSD. In the M1 processor model, 256 GB of internal storage is offered by combining two 128 GB NAND chips.
When there is more than one NAND chip in the device, it accelerates to higher speeds in parallel. However, the Macbook Pro with the M2 processor has a single 256GB NAND chip and therefore cannot achieve the same SSD speeds as the previous generation. It remains unknown at the moment why Apple made such a change.
Reducing costs is the first reason that comes to mind. It remains unknown whether the same change will be made on the Macbook Air. To summarize: Those who switch from an M1 processor to a base model M2 processor will experience an increase in CPU and GPU performance, while slowing down on the SSD side.
