The 13-inch MacBook Pro M2 shows disappointing SSD performance. Blame it on an internal configuration change.
Apple recently formalized its new generation of MacBook Pro, machines equipped with the first in-house Apple Silicon M2 chips. The presentation was, as usual, very promising, with very interesting developments. For the time being, the M2 chip is only offered on entry-level machines. And what is it exactly?
13-inch MacBook Pro M2 shows disappointing SSD performance
It turns out that the 13-inch 256GB MacBook Pro M2, the entry-level of this new generation, could have SSD performance below that of its M1 counterpart. This is what emerges from tests carried out by the YouTube channels Max Tech and Created Tech. The base model, priced at $1,599, has about 50% slower read speeds (1,446MB/s vs. 2,900MB/s) and 30% slower write speeds.
Max Tech opened up a 13-inch MacBook Pro M2 to find it only has a single 256GB NAND flash memory chip compared to two 128GB chips for the M1 model. This would mean that the disk can only handle two lines in parallel. In fact, performance is restricted to the speed of a single line.
Blame it on an internal configuration change
The higher-end 512GB and 1TB models don’t seem to be affected by this issue, and many of the test machines Apple ships have a 1TB configuration. Slower speeds on the 256GB model could affect loading applications, file transfers and data recovery. Overall performance should also be impacted as virtual memory (used when RAM is full) will be slower, and the base model only has 8GB of RAM.
It’s hard to know why Apple changed the configuration of this model. The worldwide shortage of chips could be part of the answer. Either way, it’s something to consider if you’re considering buying this 13-inch MacBook Pro M2.
