According to the tests, the 13-inch 256 GB M3 MacBook Air, also sold in Turkey, has a much faster SSD than the M2 model it replaces.
For those who missed it, the MacBook Air with M2 processor was introduced together with the 13-inch MacBook Pro with M2 processor. He had a sad detail about SSD. As it turned out after the first examinations, just like the 13-inch MacBook Pro model with M2 processor, the 256 GB SSD storage unit of the MacBook Air with M2 processor was replaced by the 256 GB SSD storage of the MacBook Air with M1 processor. SSD It was running slower than the storage unit. Within the scope of the 5 GB transfer test performed in the Blackmagic Disk Speed Test application, the 512 GB SSD version of the laptop reaches 2,187 MB/s writing and 2,824 MB/s reading speeds. The version with 256 GB SSD gives 1,573 MB/s reading and 1,536 MB/s writing values. This situation Mac mini with M2 processor And MacBook Pro It also showed itself in the models. As far as we learned from the investigations 256GB Mac mini based on M2 And New GB MacBook Pro based on M2 models compared to the M1 processor versions they replaced. It offers slower writing and reading speeds. Unfortunately, Apple did not change this situation in the 15.3-inch MacBook Air model that it introduced at WWDC23. The laptop’s 256 GB SSD unit, 512 GB ran slower than 1 TB and 2 TB versions.

Recently introduced new 13-inch 256GB M3 MacBook Air is much faster than the M2 model with 256 GB storage (1.576 vs 2.880 read speed / 1.584 vs 2.108 write speed difference) has an SSD. Because this time Apple is also on the MacBook Air at the bottom. room for dual NAND chips gives. Apple, which received a lot of criticism on this issue, corrected its mistake on the SSD side, but the model is still listed at the bottom. sells with only 8 GB RAM.
