SSD speeds of 13-inch MacBook Pro with M2 processor are disappointing

Speed ​​tests for the storage unit of the new 13-inch MacBook Pro laptop with the M2 processor, which Apple put on sale on Friday, June 24, fell on the internet. In the measurements made, it turned out that the read / write speeds of the base model equipped with a 256 GB SSD are noticeably lower than the previous generation.

Laptop tested with Blackmagic’s Disk Speed ​​Test. The read speed of the SSD was found to be 50% slower than the previous model. There is a 30% performance loss in writing speed. The declared values ​​and comparison are as follows:

Reading Speed:

• 13-inch MacBook Pro (M1/256GB): 2,900MB/s
• 13-inch MacBook Pro (M2/256GB): 1,446MB/s

Write Speed:

• 13-inch MacBook Pro (M1/256GB): 2,215MB/s
• 13-inch MacBook Pro (M2/256GB): 1,463MB/s

It was determined that the new MacBook Pro, with its disassembly, contained only one NAND flash storage chip with a capacity of 256 GB. The M1 model, on the other hand, has two NAND chips of 128 GB each. This may be the reason for the drop in performance. In the meantime, let’s point out that there is no such slowdown in 512 GB, 1 TB and 2 TB versions.
