Following the launch of Apple's new 13-inch MacBook Pro with the M2 chip, it has been discovered that the base model has significantly slower read and write speeds compared to the previous generation model.

Max Tech and Created Tech used the Disk Speed Test app to compare the read and write speeds of the 128-gigabyte model to the 13-inch MacBook and found that the read and write speeds were 50% and 30% slower, respectively.

The Disk Speed Test app numbers were shared by Vadim Yuryev.

  • 13-inch MacBook Pro (M1/256GB) Read Speed: 2,900
  • 13-inch MacBook Pro (M2/256GB) Read Speed: 1,446
  • 13-inch MacBook Pro (M1/256GB) Write Speed: 2,215
  • 13-inch MacBook Pro (M2/256GB) Write Speed: 1,463

The new MacBook Pro has only a single flash storage chip, whereas the previous model has two, according to Yuryev. The new model has slower speeds due to the fact that multiple chips allow for faster speeds in parallel.

Only the base model 13-inch MacBook Pro with M2 chip has a slowerSSD. If you want to get the same read and write speeds as the M1 models, you'll need to spend at least $150,000. It's possible that the 512GB model still has two flash storage chips.

Costs and/or supply constraints are possible reasons why the new base model 13-inch MacBook Pro is only equipped with a single chip. If we hear back, we'll update this story.

Since Macs temporarily use SSD space as virtual memory, slower speeds can affect common tasks such as transferring files to an external drive. If you're thinking about buying a new 13-inch MacBook Pro, we recommend ordering a model with at least 512GB of storage, since it's important to you.

The new MacBook Pro is 13 inches in size. The base model's slower speeds were not mentioned in many embargoed reviews of the notebook, as it appears that Apple gave many reviewers with a 1 terabytes configuration for testing.

It's not clear if the new MacBook Air with the M2 chip will have slower speeds when configured with more storage.
