Apple’s brand new M2 powered MacBook Pro, which has promised a boost in performance over its predecessor, sports one major downgrade that will affect speeds compared to the M1.
As reported by MacRumours, tech YouTubers Max Tech and Created Tech found that the base model 13-inch M2 MacBook Pro had 50% slower SSD read speeds and 30% slower SSD write speeds.
Max Tech says the speeds are as follows:
| 13-inch MacBook Pro (M1/256GB) | 13-inch MacBook Pro (M2/256GB) | |
| Read | 2,900MB/s | 1,446MB/s |
| Write | 2,215MB/s | 1,463MB/s |
Both YouTubers concluded that the new SSD’s NAND flash configuration was to blame, as the M1 was fitted with dual 128GB chips whilst the M2 model has only one 256GB chip. Using two NAND chips at once results in greater speed.
Higher end M2 laptops seem to be unaffected by the issue.
