Was it always like this with Windows and SW Bitlocker then? On the Mac, for more than 10 years Filevault FDE has been unnoticeable in terms of a performance hit. I remember that back then, before Macs had SSDs they also offered FV that only encrypted the user folder.

- acdha 3y agoI’d want to see real benchmarks to make sure that’s not due to a confound (e.g. updates used to be slowed by things like Homebrew having huge numbers of files in the /usr/local directory which were inefficiently moved & restored by the installer). Every time I’ve tested it the difference has been negligible.

There is not an additional performance hit with FileVault. 1. https://support.apple.com/guide/security/data-protection-overview-secf6276da8a/web https://support.apple.com/guide/security/data-protection-ove... 2. https://support.apple.com/guide/security/volume-encryption-with-filevault-sec4c6dc1b6e/web https://support.apple.com/guide/security/volume-encryption-w...
- mickelsen 3y agoWow! So this explains why setting it up later down the road is almost instant on Macs with T2 or M1/M2? Because IIRC with <2016 macs there was a long wait if you already have been using that disk for a while.
- speedgoose 3y agoThanks, that's good to know.
