Benchmarks show that MacBook Pro with M2 has a much slower SSD data transfer speed than MacBook Pro with M1 –GIGAZINE

WWDC22Among them, Apple is the next generation of SoC for Mac”M2And a new model equipped with M2MacBook Air and MacBook Proannounced. The “256GB” SSD-equipped model, the base model of the new M2-equipped MacBook Pro, has a much slower data transfer speed than the 256GB SSD of the previous generation M1-equipped MacBook Pro-equipped base model. explained.

YouTube channels such as Max Tech and Created Tech are standard software for measuring the throughput of storage such as hard disks and SSDs.Blackmagic Disk Speed ​​TestUsed to measure and compare the data transfer speed of the 256GB SSD installed in the base model of the 13-inch MacBook Pro M2 and the 256GB SSD base model of the 13-inch MacBook Pro with the M1 predecessor. .

Below is Max Tech’s SSD test result for the M2-equipped MacBook Pro (256GB/SSD) and the M1-equipped MacBook Pro (256GB/SSD) using Blackmagic Disk Speed ​​Test. The M1-equipped MacBook Pro (512GB/SSD) read speed is 2,900MB/s, while the M2-equipped MacBook Pro (256GB/SSD) has a read speed of 1446MB/s, which is about 50% slower.

The write speed of the M1-equipped MacBook Pro (512GB / SSD) is 2215 MB / s, while the MacBook Pro equipped with the M2 (256 GB / SSD) is 1463 MB / s, which means that the speed is reduced by about 34%.

Below are the results of an SSD benchmarking program using Blackmagic Disk Speed ​​Test by Created Tech. Again, the MacBook Pro (256GB/SSD) equipped MacBook Pro has a write speed of 2046.3MB/s and a read speed of 2924.6MB/s. The write speed of the M2-equipped MacBook Pro (256GB/SSD) is 1551.3MB/s, and the read speed is 1479.1MB/s.

Another standard program,”Aja Test Lite SystemThe result of measuring the data transfer speed of an SSD using “” is as follows. The write speed of the MacBook Pro equipped with the M1 (256 GB / SSD) is 2207 MB / s, and the reading speed is 2822 MB / s. The write speed of the MacBook Pro (256 GB / SSD) equipped with the M2 is 2366 MB / s, and the reading speed is 1096 MB / s.

On average, the SSD of an M2-equipped MacBook Pro (256GB/SSD) has a read speed of about 50% and a write speed of about 30% slower than a MacBook Pro equipped with an M1 (256GB/SSD).

As a result of disassembly of the M2-equipped MacBook Pro (256GB/SSD), it only has a single 256GB NAND flash storage chip, but in the case of the previous M1-equipped MacBook Pro (256GB/SSD) model, it appears that two are installed 128GB NAND flash storage chips. “Multiple NAND flash storage chips installed in parallel may have contributed to the speed increase,” said MacRumors, an Apple-linked media.

However, the data transfer speed of the SSD is only slow for the base model M2 equipped with the MacBook Pro (256 GB / SSD), and the SSD of the M2 equipped with the MacBook Pro (512 GB / SSD) is the same as the M1 equipped with the MacBook Pro. It seems to be speed. MacRumors writes, “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.” a plus.

It’s unclear why the M2-equipped MacBook Pro (256GB/SSD) will only have a single NAND flash storage chip, but MacRumors notes that there may be cost and supply limitations. If the data transfer speed of the SSD is slow, it may affect you when performing common tasks such as “moving files to an external drive”, which also leads to poor performance when using the SSD as virtual memory. MacRumors recommends “Choose 512GB or more of storage” or “Wait until the MacBook Air running M2 comes out in July” if you want to buy a MacBook Pro running M2.
