Base 13-Inch MacBook Pro With M2 Chip Has Significantly Slower SSD Speeds
Following the launch of Apple's new 13-inch MacBook Pro with the M2 chip,
it has been discovered that the $1,299 base model with 256GB of storage has significantly
slower SSD read/write speeds compared to the equivalent previous-generation model.
YouTube channels such as Max Tech and Created Tech tested the 256GB model with Blackmagic's
Disk Speed Test app and found that the SSD's read and write speeds are both around 1,450 MB/s,
which is around 50% slower reading and around 30% slower writing
compared to the 13-inch MacBook Pro with the M1 chip and 256GB of storage.
Yuryev disassembled the new 13-inch MacBook Pro and discovered that the 256GB model is
equipped with only a single NAND flash storage chip, whereas the previous model has two NAND
chips that are likely 128GB each. This difference likely explains why the new model has a slower SSD, as multiple NAND chips allows for faster speeds in parallel.
