Tested: Windows 11 Pro’s On-By-Default Encryption Slows SSDs Up to 45%::Windows 11 Pro defaults to BitLocker being turned on, using software encryption. We’ve tested the Samsung 990 Pro with hardware encryption to show how the various modes impact performance, and how muc
How bad do Macs slow down with encryption? Or can you even turn it off? They do have a dedicated chip, and section of chip, to handle encryption.
They don’t slow down with encryption to any real degree.
Even before Apple added their dedicated T or M chips, they used the AES instruction set in Intel CPUs for hardware acceleration and the performance impact was within the margin of error (3%) https://archive.techarp.com/showarticle0037.html?artno=877&pgno=1
