Base 13-inch MacBook Pro with M2 chip has significantly lower SSD speeds

Following the launch of Apple’s new 13-inch MacBook Pro with the M2 chip, it has been discovered that the $ 1,299 base model with 256 GB of storage has significantly lower read / write speeds on the SSD compared to the equivalent of the previous generation model.

YouTube channels such as Max Tech and Created Tech tested the 256GB model with the Blackmagics Disk Speed ​​Test app and found that the SSD’s read and write speeds are both around 1450 MB / s, which is around 50% slower reading and around 30% slower typing compared to the 13-inch MacBook Pro with M1 chip and 256 GB of storage.

Disk Speed ​​Test App Numbers Shared By Vadim Yuryev of Max Tech:

  • 13-inch MacBook Pro (M1 / 256GB) Read Speed: 2900
  • 13-inch MacBook Pro (M2 / 256GB) Read Speed: 1446
  • 13-inch MacBook Pro (M1 / 256GB) Print speed: 2215
  • 13-inch MacBook Pro (M2 / 256GB) write speed: 1463

Yuryev dismantled the new 13-inch MacBook Pro and discovered that the 256 GB model is equipped with only a single NAND flash storage chip, while the previous model has two NAND chips that are probably 128 GB each. This difference probably explains why the new model has a slower SSD, since more NAND chips allow for faster speeds in parallel.

It seems that only the base model 13-inch MacBook Pro with M2 chip has a slower SSD. As mentioned in MacRumors Forums, Aaron Zollo ran the Disk Speed ​​Test app on the 512 GB model, and the SSD’s read / write speeds were the same as all M1 models, but getting those speeds would require spending at least $ 1,499. This probably means that the 512 GB model is still equipped with two 256 GB flash storage chips.

It is unclear why the new base model 13-inch MacBook Pro is only equipped with a single NAND chip, but cost and / or supply constraints are two possible factors. We have contacted Apple for comments and will update this story if we hear back.

Slower SSD speeds can affect common tasks such as transferring files to a remote drive, and overall performance can also be a bit of a shock since Macs temporarily use SSD space as virtual memory when physical RAM is fully used. If you’re considering the new 13-inch MacBook Pro and faster SSD speeds are important to you, we recommend ordering a model with at least 512GB of storage (or better yet, wait for the new MacBook Air in July).

The new 13-inch MacBook Pro was launched on Friday. The slower SSD speeds of the base model were not mentioned in many (any?) Embargo reviews of the laptop, as it seems that Apple gave many reviewers a 1TB configuration for testing.

It remains to be seen whether the new MacBook Air with the M2 chip will also have lower SSD speeds when configured with 256 GB of storage.
