A detailed analysis of the new Mac mini shared by YouTube channel Brandon Geekabit reveals that the 256GB model is only equipped with a single 256GB storage chip, while the same configuration with the M1 chip has two 128GB chips. This difference explains why the new model has a slower SSD, as more NAND chips allow for faster speeds.

Macrumors confirmed with the benchmarking app Blackmagic Disk Speed ​​Test that the read and write speeds of the new 256GB SSD for Mac mini are around 1,500 MB/s, 30% to 50% slower than read and write speeds. records of the previous generation. -model generation, although benchmark results and real-world performance may vary.

Customers looking for the fastest SSD speeds should make sure they configure the M2 Mac mini with at least 512GB of storage to avoid this issue. A slower SSD can affect file transfer speeds, and overall performance can also be slightly affected as Macs temporarily use SSD space as virtual memory when physical RAM is used up.

As for the higher-end Mac mini with the M2 Pro chip, the base model with 512GB of storage appears to have two fewer NAND chips than the Intel-based model it replaced, according to an analysis shared by Microsoft. Brian Stucki of MacStadium.

The 13-inch MacBook Pro and MacBook Air models with the M2 chip and 256GB of storage also have slower SSD speeds due to only one NAND chip, and it’s clear that Apple hasn’t decided to change course with the new Mac mini.

In a statement shared with The Verge last year, Apple claimed that M2-based Macs have “even faster” performance for real-world operations, but it’s unclear whether this statement refers To refer to SSD performance or overall system performance:

Thanks to the performance boost of the M2, the new MacBook Air and 13-inch MacBook Pro are incredibly fast, even compared to Mac laptops with the powerful M1 chip. These new systems use new, higher-density NAND, providing 256GB of storage with just one chip. While the 256GB SSD benchmark may show a difference from the previous generation, the performance of these M2-based systems for real-world operations is even faster.

We’ve reached out to an Apple spokesperson for further comment on this matter and will update this story if we receive a response.

Update: As noted by 9to5Mac, the new MacBook Pro also has slower SSD speeds when configured with 512GB of storage due to reduced NAND chips.

Therefore, despite being significantly cheaper, users will also need certain attention if they plan to buy a Mac Mini or Macbook Pro using the new M2 chip from Apple.
