I have AMD Quad-Core Phenom II 955 @ 3.2GHz (It can go up to 3.8 if needed).
I may get high performance SSD (500 MB/s write/read) and if I encrypt the whole volume how much of a performance hit would I take?
Yes, encrypting 7200rpm HDDs won't have no performance hits because they are slow anyway. But if I encrypt a SSD what should I be looking at? My CPU got to get memory from SSD -> Decrypt -> RAM then RAM -> Encrypt -> SSD. In-game performance won't be hurt that much as they run from RAM but the loading times will.
However if I can only decrypt at 300 MB/s or something it will be very bad since I be getting a SSD for the performance.
Of course, one day I will upgrade my CPU again. But that's after I get a 2x SSD enclosure, 2x SSD, among other things and a laptop supporting USB3.
Little side question. USB3 will support 500 MB/s? I assume so since the spec of USB3 but I like to see your opinions.
