New MacBook Pros with M2 Pro and M2 Max processors have begun to reach buyers and tech reviewers. And while the former enjoy fresh laptops, the latter found something to complain about in the update.

This is about repeating history with 13-inch MacBook Pro and MacBook Air with M2 processors. These models changed the capacity of individual NAND chips, which, accordingly, became noticeable in the speed of the drives. Unfortunately, not for the better.

9to5Mac’s Derek Wise ran the Blackmagic Disk Speed Test on a new MacBook Pro model. His test instance is the basic version with M2 Pro and 512 GB of permanent memory. The result is not that disappointing, but compared to the previous model, it still loses — 3154.5/2973.4 MB/s versus 3950.8/4900.3 MB/s, respectively.

After opening the top case, Mr. Wise confirmed that the chip combination had indeed changed. The previous model had four separate chips of 128 GB each, while the new model has only two of them with a correspondingly doubled capacity.

The storage devices of the new MacBook Pro have slowed down as well as in other models of Apple laptops

According to other media that received models with larger storage capacities (Macworld, Tom’s Guide), this slowdown “affected” only the base models. But taking into account the cost of such laptops and their “target” at professional users, such a slowdown in the read and write speed (especially in the given example) data still remains an unpleasant moment.
