MacRumors Forums member abbotsford1980 has revealed the results obtained with his new M1 MacBook Air with a 256 GB SSD in Blackmagicdesign's Disk Speed Test and also what he got with the 2019
My MacBook Air is really slow, beachballing a lot. Tested write speed of about 200 MB/s with Transcend JetDrive 820 (1TB), while it was about 600 MB/s with the original one (128GB). In order to get these results, I use: I noticed that reported JetDrive connectivity is AHCI PCIe x1 (while advertised at x2). The original SSD reports AHCI PCIe x4.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.
M2 15" MacBook Air with 24GB ram and 1/2TO SSD is absolutely not a good deal but nevertheless a wonderful machine. It is that simple. Moneywise, the good deals are the base Macbook pro 14" and the maxed out 16" Macbook pro.ipHPhoL. 681 266 639 471 641 472 726 227
