In response to VeeJay <maanjee@gmail.com>: > > Does *disk encryption* causes a *performance* penalty for Data > Access/Read/Write, etc? Any kind of encryption causes a performance penalty. However, if your CPU is powerful enough, it's possible (even likely) that the CPU is still able to encrypt faster than the disk can write the data. The result would be that you won't notice the penalty unless you've got other CPU-intensive tasks running that reduce the amount of CPU available to the encryption process.
