Unfortunately, despite of the CPU and GPU improvements in the new model, they might end up losing on SSD performance. There are M1 MacBook Pro users who are considering upgrading to the M2 model with 256GB. By using a single NAND chip instead of two, the company is possibly trying to reduce costs. On the other hand, the M1 model has two NAND chips that are likely 128GB each.Īs multiple NAND chips allows for faster speeds in parallel, the difference in storage chip of the Macbooks is likely the reason why the new model has a slower SSD speed.Īccording to 9to5Mac, the reason why Apple changed the SSD in the entry-level M2 MacBook Pro model is unclear yet. Upon opening of the unit, he discovered that the 256GB model is equipped with only a single NAND flash storage chip. To find out the reason behind the slower reading, Vadim Yuryev of Max Tech disassembled the new 13-inch MacBook Pro. In terms of writing speed, M2 Macbook Pro got 1,463 Mbps speed, which 30% slower than M1 Macbook Pro's 2,215 Mbps. ![]() It was found out that in terms of read speed, M2 Macbook Pro got 1,446 Mbps speed, which is around 50% slower reading than the M1 Macbook Pro's 2,900 Mbps. ![]() ![]() Using Blackmagic's Disk Speed Test app (the benchmark app that allows users to test the performance and measure the transfer speed of any internal or external storage on a Mac), YouTube channels such as Max Tech and Created Tech tested the 256GB model, as per MacRumors report.
