Apple introduced a new Mac mini computer and two new 2023 MacBook Pro models in a press release on January 19. Next-generation Mac products include: M2, M2 Pro and M2 Max chips with great strength.

But the arrival of the new Macs in stores caused the first reviews to appear. slower SSD hard drive read and write speed more than usual, at least on entry-level Mac mini and MacBook Pro models.

Despite the sheer performance power of the M2 Pro and M2 Max chips, SSDs fall short due to their NAND chip configuration.

The entry-level MacBook Pro has a slower SSD than previous generations

At 9to5mac, we took a good look inside the MacBook Pro to find out what happened to the hardware components, and found that it has fewer NAND chips than the previous generation.

MacBook Pro with 512GB M2 chip You have a single NAND chip visible on your motherboard The (bigger) MacBook Pro with the M1 chip had two 128GB NAND chips on one side of the motherboard and two chips of the same capacity on the other side. This is the reason why SSD drive performance is poor as a result.

As seen in the image, a comparison between the write and read speeds of the SSD hard disk of the MacBook Pro with the M1 chip and the write and read speeds of the MacBook Pro with the M2 Pro chip reveals the following: performance is slower in the new generation.

It is worth noting that only happens on entry-level MacBook Pro It has a capacity of 512 GB and despite this, the performance of the SSD drive is still very high. MacBook Pro users will not notice any significant changes in daily use. However, it is still a very disappointing fact that Apple has made it clear in the presentation of its products.

On the other hand, the basic model macmini The M2 chip with a 256GB SSD also has slower read and write speeds than the previous generation.
