Although the new M2 chip implement performance improvements M1, it seems that this is not the case when it comes to storage speed. Tests performed with the new MacBook Pro M2 reveal that the entry-level model has a slower SSD than the M1 model.
As noted by YouTube channels such as Max Tech and Created Tech (as explained by MacRumors), the base model of the new MacBook Pro M2, which has a whopping 256GB of storage, offers slower SSD speeds than the previous-generation 13-inch MacBook Pro with M1. Tests were performed with Blackmagic Disk Speed Testa reference app that allows users to test the performance and measure the transfer speed of any internal or external memory on a Mac, the surprise came when instead of providing better results than its predecessor, the 256GB MacBook Pro M2 got worse in terms of storage speed.
The benchmarks show that the SSD in the entry-level MacBook Pro M2 is 34% slower than the M1 model in terms of writing speed, while the difference in reading speed can be up to 50%.
Here are the results of one of the benchmark tests conducted by the Max Tech YouTube channel:
However, the lower SSD performance doesn’t seem to affect the more expensive M2 MacBook Pro models with more internal memory. YouTuber Aaron Zollo of Zollotech shows that the 512GB MacBook Pro M2 has very similar SSD speeds to the M1 model.
Created Tech removed the bottom of the new MacBook Pro M2 with 256GB of storage to check out the internal components, and here it turns out that Apple has actually made some changes when it comes to SSDs. The MacBook Pro M1 has two 128GB NAND chips, each in a 256GB version. When a device has multiple NAND chips combined, it can achieve faster speeds at the same time, but the MacBook Pro M2 has a single 256GB NAND chip, so therefore it cannot achieve the same SSD speeds as the 13-inch MacBook Pro. inches from the previous generation.
