Anand benchmarked FileVault(1) and his conclusion was "Overall the hit on pure I/O performance is in the 20 - 30% range. It's noticeable but not big enough to outweigh the benefits of full disk encryption."

- kgtm 15y agoYes, but that result is most likely on a Sandforce-powered SSD, which sports different transfer speeds based on the payload (compressible/incompressible). Like the GP notes, this is not a problem with SSDs in general.
- culturestate 15y agoThat benchmark is with a stock Apple SSD, which IIRC are not Sandforce-based. To be clear, I'm actually in agreement with Anand and OP - the benefits of FDE far outweigh the consequential I/O hit.
