The lowest version of the 14-inch MacBook Pro with the M2 Pro processor for SSD speed is worse than its predecessor.
Tested with BlackMagic software, the lowest configuration option of the 14-inch MacBook Pro M2 Pro gives a slower SSD speed than its predecessor.
Specifically, the 512 GB SSD on the device has a read speed of about 2,970 MB/s and a write speed of 3,150 MB/s. Meanwhile, the SSD read speed of the 14-inch MacBook Pro M1 Pro is 4,900 MB/s, and the write speed is 3,950 MB/s.
That means on the lowest version of the 14-inch MacBook Pro M2 Pro, the SSD read speed is about 39% slower, the write speed is 20% slower than its predecessor with the M1 Pro chip. The cause of the difference may be the memory chip.
According to 9to5Mac , the 512 GB version of the 14-inch MacBook Pro M1 Pro is equipped with 4 NAND chips (each with 128 GB capacity), while the M2 Pro model uses only 2 chips (256 GB each). With the same capacity, SSDs with less NAND chips are slow due to their poor ability to read and write data in parallel.
This isn't the first time Apple has released a computer with fewer NAND chips than its predecessor. MacBook Air M2 and MacBook Pro 13-inch M2 256 GB both have slower SSD speeds than their predecessors, because they only have one NAND chip instead of two.
The Mac mini M2 with 256GB SSD also has a NAND chip, but compared to the previous generation, the device's starting price is $100 cheaper .
According to the test, the 256 GB Mac mini M1 has a read speed of 2,854 MB/s and a write speed of 2,733 MB/s. Meanwhile, the SSD of the Mac mini M2 256 GB has read and write speeds of 1,482 MB/s and 1,431 MB/s, respectively.
According to The Verge , that's not a big deal because the MacBook Air and 13-inch MacBook Pro are in the mid-range segment. Meanwhile, the 14-inch MacBook Pro starts at $2,000 for high-demand needs.
It is not clear how many NAND chips the 16-inch MacBook Pro version M2 Pro with 512 GB SSD uses. A slow SSD can affect file download speeds and performance when using certain apps.
The higher options of the MacBook Pro 2023 all have faster SSD speeds than the previous generation. test In Tom's Guide's , the 2 TB SSD on the MacBook Pro M2 Pro gave a read speed of 5,293 MB/s and a write speed of 6,168 MB/s.
Of course, slow SSD speed doesn't mean the 14-inch MacBook Pro has poor performance. 's evaluation 9to5Mac shows that the device still has enough bandwidth to play 12K ProRes video at 60 fps, performing faster than the 13-inch MacBook Pro M1 in most tasks.
