Apple MacBook Pros based on the new M2 Pro SoC have started to become available. While it is not uncommon to find lower capacity drives to be somewhat slower than higher capacity ones, it looks like the new entry-level M2 Pro MacBook Pro 14’s SSD is considerably slower than the one in the M1 Pro-based MacBook Pro 14. This is a repeat of what we’ve seen before with the M2-based MacBook Pro 13 and its M1 equivalent.
According to Daniel from ZONE of TECH on YouTube, the 512 GB SSD in the MacBook Pro 14 with M1 Pro is actually 18% faster in writes (3,450 MB/s) and 50% faster in reads (4,081 MB/s) than the new 512 GB MacBook Pro 14 (2,929 MB/s write and 2,703 MB/s read) with M2 Pro in the AJA system test disk benchmark using a 16 GB 10-bit 4K test file.
The reviewer feels that this could be the case of Apple using single SSD modules similar to what we’ve seen in the 256 GB MacBook Air and MacBook Pro with the M2 chip.
Findings from 9 to 5 Mac also confirmed the use of fewer, higher capacity NAND in the M2 Pro-based MacBook Pro 14. According to the publication, in the case of the M1-powered MacBook Air, the base 256 GB storage was split between two 128 GB Kioxia NAND modules . Therefore, a 512 GB variant would use four such NAND chips — two on each side of the logic board.
In the M2 generation, however, Apple started using higher density NAND, which meant the base variant of the MacBook Air had only a single 256 GB module working in isolation.
9 to 5 Mac‘s tests show a 20% reduction in writes and a near-40% reduction in read speeds in the Blackmagicdesign Disk Speed benchmark. Opening up the 512 GB MacBook Pro 14 reveals only a visible 256 GB NAND chip along with an unpopulated space for use in higher storage configurations. The other 256 GB flash is on the underside of the logic board.
While denser flash is welcome, the perceivable difference in speeds from a previous generation Mac is somewhat disappointing. That being said, the speed impact may not be felt in real-world usage. ZONE of TECH observed that the M2 Pro-powered MacBook Pro 14 can actually be faster in tasks like file copying although Lightroom imports were 2.25x slower with the newer machine.
The net experience with M2 Pro still seems somewhat faster despite the slower SSD given the overall performance advantage over the M1 Pro-powered MacBook Pro, although for most workflows it’s just splitting hairs. Most users are unlikely to notice the SSD performance fails unless they are into long sustained read/writes. Right now, the only workaround is to opt for a MacBook Pro with at least 1 TB of storage at checkout.
Given the nominal performance differences and the slower flash, it might actually make better economic sense to opt for the M1 Pro-powered MacBook Pro if you’re looking at entry-level variants and save a decent amount of cash particularly with refurbished ones. Stay tuned for our full review for more on that.

Although a cell and molecular biologist by training, I have been drawn towards computers from a very young age ever since I got my first PC in 1998. My passion for technology grew quite exponentially with the times, and it has been an incredible experience from being a much solicited source for tech advice and troubleshooting among family and friends to join Notebookcheck in 2017 as a professional tech journalist. Now, I am a Lead Editor at Notebookcheck covering news and reviews encompassing a wide gamut of the technology landscape for Indian and global audiences. When I am not hunting for the next big story or taking complex measurements for reviews, you can find me unwinding to a nice read, listening to some soulful music, or trying out a new game.
