- x0054 13y agoHow does encrypted SSD perform, compared to unencrypted? My SSD does reads/writes in the 500MB/s range. Does encryption significantly slow down performance?
- tmikaeld 13y agoIt's up to the CPU actually and most CPU's have the AES instructionset by default. In this case, the performance hit is minuscule.

- Groxx 13y agoIt does slow things down technically, but not by much. You won't notice it.
- wyager 13y agoOS X and iOS heavily leverage the AES-NI instruction set (and whatever the equivalent is on ARM), so performance degradation is minimal.
- aaronpeck 13y agoIt's noticeable for sure. My Samsung 830 SSD took a pretty serious hit in transfer rates. New full flash based Mac's like my late '13 retina i7 seems to handle it pretty well, though, there's still a noticeable difference. Worth it? Absolutely. If you do end up doing it - when prompted, I would recommend against saving your encryption key to iCloud.
- kybernetyk 13y agoI don't feel/see any performance loss at all. (I'm developing audio processing software). I guess there is some performance degradation but unless you constantly max out your SSD you probably won't notice anything.
- x0054 13y agoJust turned it on on my 15" 2012 rMBP and it finished encrypting the drive. Before I was getting around 520-540MB/s read/write. Now it's 440-460MB/s. It's not a large hit, slightly noticeable, but worth the security. I am not sure about battery life, but I could not see any one else online complaining.
- tmikaeld 13y agoDo you mean that rubberduck doesn't work or that protecting with encryption doesn't work?
