A few days ago, Apple announced new 14-inch and 16-inch MacBook Pros with M2 Pro and M2 Max processors, as well as a new Mac mini with M2 and M2 Pro processors, which feature faster performance and longer battery life. life, and some additional features. , such as support for WI-Fi 6E and the 6GHz band. However, there are some specifications that the company has not officially shared, and which, fortunately, we can find out thanks to some users who have completely disassembled the product. This is exactly what some users have done They found that new computers have a slower SSD than their predecessors.

YouTube channel Brandon Geekabit, for example, confirmed that a Mac mini with an M2 processor and 256 GB of internal memory, they only have a NAND memory chip SSD, while the previous generation with the M1 chip includes two chips of 128 GB each. While the total memory is exactly the same, the fact that the storage is shared between two NAND modules allows for much faster read and write speeds.

In fact, as detailed in the test MacRumors Thanks to the Blackmagic Disk Speed ​​Test, the new Mac mini with 256GB M2 storage achieves read and write speeds of around 1500MB/s. Thus, they are 30-50% slower than their predecessors.they assure. The 512GB version, on the other hand, offers exactly the same SSD speeds as the same Mac mini variant with the M1 chip, since its memory is also spread across multiple NAND storage chips.

According to 9to5Mac, The 512GB MacBook Pro M2 Pro also has a slower SSD than its predecessor., since the distribution of SSD memory is carried out in fewer NAND chips. “Where the 512GB MacBook Pro M1 Pro had two visible NAND chips on the front of the motherboard and two on the back, the MacBook Pro M2 Pro only had one visible on the front of the motherboard,” he says. equipment.

The new MacBook Pro and Mac mini have a slower SSD, but should we be concerned?

Interestingly, this is not the first time that a lower SSD speed than the previous version of an Apple device has been reported. The 13-inch MacBook Air and MacBook Pro with M2 chip and 256 GB of memory also have the same problem. However, does it bother you?

Apple previously claimed that edge The MacBook Pro and MacBook Air use higher density NAND to store 256GB on a single chip. “While tests of 256GB SSDs may show a difference compared to the previous generation, these M2-based systems still perform better for real-world use.” In addition, despite the significant difference in read and write speeds of SSDs, it is unlikely that a user will notice a huge difference.
