View attachment 760495. Read speed is reduced by 31% and write speed by 11%. I know the 2017 model has different faster storage but reductions will occur, but not necessarily the same percentages. I have seen quite wide range of reported results for the effect of Filevault, including larger reductions.
I have the Macbook Air M2 in two configurations: base and 16/512. The base model is perfectly fine for normal use, like browsing the web, email, office, that kind of stuff. File transfers are not the fastest when copying from USB sticks, but other than that you notice very little even when it starts swapping to disk when RAM is full.
interesting 1300 read and writes on the 512GB 2020 MBA. I am a little disappointed. I get 1900 writes and 2700 reads on my 2018 mac mini 500GB, I get 1800 and 1900 on my 500GB 2017 MBP. I think 1300 speeds matches my old 256GB 2016 13" MBP.
The Retina 15" mid 2015 supports 4x lanes PCIe 3.0 speed eg. up to 3000MB/s. The early 2015 Retina 13" supports 4x lanes PCIe 2.0 speed. They do both natively support hibernation on NVMe SSD.

In the 2015 MacBook Air, it runs at a measly 1.6 GHz, but the Turbo Boost can reach up to 2.7 GHz. The large Turbo Boost of the MacBook Air makes it seem competitive, but will it ever really reach that clock speed? The base M2 Air has noticeably higher 4k random read speeds than the M1 Air, and marginally higher 4k random write speeds. Pulling results for some of the most common Mac configs. For consistency, all results are the average of 5 random read/write attempts of a 1 GB payload, QD1: Base M1 Air. Random 4K Read: 40.29 MBps. The “high-end” version of each model gets a CPU speed bump option (a 1.8GHz i5, in both cases, for $150 in the 11" and $100 in the 13"), and the high-end 11" model has a 256GB SSD option for .
