if The new MacBook Pro And mac mini Equipped with the unprecedented M2 Pro and M2 Max It easily outperforms the competition in SSD speed, the situation is not very favorable compared to its predecessors. Several tests conducted by specialized vehicles revealed that the launches An apple They offer lower transfer rates compared to the previous generation, due to the same resolution It hampered the performance of the MacBook Air M2 – Use a few memories.
Although not as revolutionary as the first generation of devices with Apple Silicon, the recently announced 14- and 16-inch MacBook Pros, as well as the 2023 Mac Mini, have drawn attention as they come. of M2 Pro and M2 Max chipsConsistently more powerful than Apple’s first generation processors. Compared to their predecessors, both showed average gains of 20% in CPU and 30% in GPU, as well as higher numbers in AI and video rendering.
However, users who purchase the basic version of one of these novelties will not have a very pleasant surprise: the SSD storage used by Apple is slower than that of the MacBook Pro and Mac Mini with the M1. The first tests were made by the site 9to5Mac It reveals a 30% to 50% reduction in transfer speeds compared to older machines. Self-made clippings 9to5Mac and on the YouTube channel Brandon Gikabit Determine why: Only one volume is used instead of two or more.
Base versions of the MacBook Pro and older Mac Mini adopted low-density NAND memory (the kind intended for storage), which required the brand to use two or more modules to reach 256GB or 512GB. In the end, this architecture gave positive results, since there are two or even four communication channels for data transmission, which guarantee very high speeds.
With devices equipped with the M2, M2 Pro, and M2 Max, the situation has changed: denser NAND memories were used, which prompted Apple to reduce the number of chips installed to 1. As a result, data was limited to traveling on a single channel, which led to significant downgrades. The noticeable, especially when we consider that these devices are completely inaccessible and we seek the service of specialists.
The curious situation is even more delicate with the 512GB MacBook Pro 14 – although it has more capacity than the Mac Mini by default, the number of installed NANDs compared to the M1 Pro chip-equipped model has dropped from 4 to just 2, which limits transfer rates in the same way. . None of the tests evaluated the 16-inch MacBook Pro, but it’s possible that the larger machine also suffers from a similar problem in its simplest form.
It should be noted that this is not the first time this has happened with Apple devices – in the past year, the company has been involved in controversy with MacBook Air M2 for the same reason. The company has ensured that this won’t be noticed in everyday use, thanks to the faster M2, an answer to be given again by discussions involving new Macs.
It is important to note that this does not completely negate the performance gains of the new processors, and in the case of users and professionals who need the improvements offered by the new generation without being able to spend a lot, these versions are still welcome. However, it is always disappointing to see a product debut with ratings downgrades compared to its predecessors, leaving the recommendation to avoid it, and to invest a bit more to get models with a larger capacity, which will guarantee fast SSD speeds.
