You will only get 1400-1500 MB/s read/write speeds as the bus is PCIe 2.0 x4 speed. I have the same limitation on my 2017 MacBook Air with the Samsung 970 EVO that is actually capable of 3500/2500 read/write speeds on a full PCIe 3.0 x4 bus, which the Air does not have on 2017 and earlier. alexplank. • 1 yr. ago. If the benchmarks are to be believed, TB3 SSDs are definitely faster than the internal SSD in the base m2 air. I've seen the benchmarks for the M2 air and my TB3 SSD is close to the the air's 512GB SSD (faster for some tests) and significantly faster than the air's 256GB SSD. I get ~2600 megabytes per second r/W on my I happened to purchased two Macbook Air 11" with 128GB Storage this year, one in late June and another recently. Surprisingly, the later one uses the updated NVMe SSD just like the 12" Macbook (only in a blade form) as opposed to the AHCI PCI-e SSD. The verdict: Although the write speed is equal to the PCI-e ranging from 270MBps to 300MBps The 1TB SSD in the MacBook Air we tested hit a read speed of 2692 MBps on the Black Magic Disk Speed Test (Intel), literally more than twice the 1,301.9 MBps read rate from the Intel MacBook Air.

Capable of moving over 500 megabytes per second, the new hardware triples the system's storage performance, and this all looks great on paper. This burned me… I ordered a m2 pro mini with the base 16gb/512gb. I figured that would avoids the low speed issue people were complaining about in the base air, but I was wrong. Would have probably upgraded if I knew there was a performance delta. Though the Mac mini this is replacing has a SATA SSD, so this is still going to be much faster.
