The cheapest next-gen MacBook Pro has a slower SSD than its predecessor. We’re talking about the cheapest version of the 14-inch MacBook Pro, which uses the Apple M2 Pro chip and has a 512GB SSD – its storage was slower than the storage of the previous generation counterpart on the M1 Pro . That’s what 9to5Mac’s BlackMagic Disk Speed Test proves.
It turns out that the base 14-inch MacBook Pro with a 512GB SSD delivered 2970MB/s reading and 3150MB/s writing, compared to the previous-generation MacBook Pro with the same SSD capacity In other words, the base 2023 model was 39% and 20% slower, respectively.
According to 9to5Mac, the reason seems to lie in the memory chips. Where the previous generation laptop used a drive with four 128GB chips, the version with the M2 Pro has two 256GB chips. Although they are larger than the previous ones, the overall throughput is lower due to the use of fewer channels. That’s why the newer MacBook Pros with more memory don’t have these problems – according to Tom’s Guide, the latest 14-inch MacBook Pro with 2TB of memory delivers 5293MB/s read and 6168MB/s write. A TB costs $600 more than the 512GB version.
The use of SSDs with fewer chips was typical for Apple in the past. For example, the MacBook Air and 13-inch MacBook Pro with M2 chips and 256GB have less fast storage than the M1 versions of the same machines. The situation was even worse since a NAND chip was used in the cases mentioned. Back then, however, we were talking about laptops in a relatively cheap price segment, while the 14-inch MacBook Pro costs at least $1999 and is designed for heavy workloads.
However, the base 16-inch MacBook Pro, which also comes with a 512GB SSD, hasn’t received any such reports, nor has the Mac mini, which has a 256GB SSD. According to journalists, Apple itself has not yet commented on the inquiries. Anyway, MacRumors reports that the Mac mini only has a NAND chip, just like the MacBook Air and 13-inch MacBook Pro. However, the new-generation Mac mini costs $100 less than its predecessor.
