YouTube channels such as Max Tech and Created Tech will be installed on the base model of the 13-inch MacBook Pro with M2 using the Blackmagic Disk Speed Test , a benchmark software for measuring the data transfer speed of storage such as hard disks and SSDs. The data transfer speed of the 256GB SSD and the base model 256GB SSD of the 13-inch MacBook Pro equipped with the previous model M1 is measured and compared.
Below is the result of Max Tech benchmarking the SSD of M2-equipped MacBook Pro (256GB / SSD) and M1-equipped MacBook Pro (256GB / SSD) using Blackmagic Disk Speed Test. The reading speed of the M1 equipped MacBook Pro (512GB / SSD) is 2900MB / s, while that of the M2 equipped MacBook Pro (256GB / SSD) is 1446MB / s, which is about 50% slower.
The writing speed of the M1 equipped MacBook Pro (512GB / SSD) is 2215MB / s, while that of the M2 equipped MacBook Pro (256GB / SSD) is 1463MB / s, which is about 34% slower.
Below are the results of SSD benchmarking software using Blackmagic Disk Speed Test by Created Tech. Again, the M1 equipped MacBook Pro (256GB / SSD) has a writing speed of 2046.3MB / s and a reading speed of 2924.6MB / s. The writing speed of the M2-equipped MacBook Pro (256GB / SSD) is 1551.3MB / s, and the reading speed is 1479.1MB / s.
Below is the result of measuring the data transfer speed of SSD using another benchmark software '
On average, the SSD of the M2-equipped MacBook Pro (256GB / SSD) has a read speed of about 50% and a write speed of about 30% slower than the M1-equipped MacBook Pro (256GB / SSD). Become.
As a result of disassembling the M2-equipped MacBook Pro (256GB / SSD), it has only one 256GB NAND flash storage chip, but in the case of the previous model M1-equipped MacBook Pro (256GB / SSD), It seems that two 128GB NAND flash storage chips are installed. MacRumors, an Apple-related media, said, 'Multiple NAND flash storage chips installed in parallel may have contributed to the increase in speed.'
However, the data transfer speed of SSD is slow only for the base model M2 equipped MacBook Pro (256GB / SSD), and the SSD of M2 equipped MacBook Pro (512GB / SSD) is the same data transfer as M1 equipped MacBook Pro. It seems that it is speed. MacRumors wrote, 'The data transfer speed of the M2-equipped MacBook Pro (512GB SSD) is equivalent to that of the M1-equipped MacBook Pro because it has two 256GB NAND flash storage chips.' increase.
It's unclear why only the M2-equipped MacBook Pro (256GB / SSD) has only one NAND flash storage chip, but MacRumors cites the possibility of cost and supply constraints. If the data transfer speed of SSD is slow, it may affect you when performing common tasks such as 'transfer files to external drive', which also leads to poor performance when using SSD as virtual memory. MacRumors recommends 'choose 512GB or more storage' or 'wait for the M2-powered MacBook Air to be available in July' if you want to buy an M2-powered MacBook Pro.
