If that isn’t fast enough, combine two of them into a RAID (using two TB ports) for a combined performance of 3800 MB/s write and 4400 MB/s read. And it’s not a small difference: The new M2-based laptop has SSD read speeds that are 50 percent slower, while write speeds take a 30 percent hit. Max Tech took apart the 13-inch MacBook Pro and This is definitely right, my Early 2015 MBP 13" was able to provide almost 700-800MB/s write and 1400MB/s read at the time like it was new, in 2016-2017 etc. However nowadays it is almost 500MB/s One notable detail confirmed by The Verge is that the $1,199 base model equipped with 256GB of storage has a single NAND chip, which will lead to slower SSD speeds in benchmark testing, but real-world performance may vary. Last month, it was discovered that the 256GB model of the 13-inch MacBook Pro with the M2 chip has up to 50% slower SSD Further confirmation came this afternoon from Mac-centric website 9to5Mac, which also noticed slower performance with the new base model MacBook Pro.The publication used the Blackmagic Disk Speed Only the MacBook Air's time of 3:43 came close. According to Apple, the 128GB PCI-based flash memory in the 2015 MacBook Pro is up to two times faster than last year's model, and in our testing The M2 Max edition of the same model managed very similar scores, at 5,319MBps for reads, 6,402MBps for writes. These speeds are a big jump from the previous generation for write speeds, it Lastly, we ran the Blackmagic disk speed test to measure the 15-inch MacBook Air’s SSD performance. It achieved a 2,793 MBps read speed and 3,145 MBps write speed. Those speeds put it above the KkunH.
