Even if x86 CPU is faster than the ARM controller, twice is slower than once.)To see what AES-NI can accomplish, I ran a few benchmarks in VeraCrypt. But the CPU would be encrypting everything a second time after that SSD's ARM processor had already encrypted it once. In a sense, AES-NI is a form of hardware acceleration.But it won't be as fast as having an SED, because an SED is already encrypting anything anyway, so using AES-NI means encrypting everything a second time after it has already been encrypted by the SSD.(I would hazard a guess and speculate that a high-end CPU (say, an Intel Core i7) can perform AES encryption faster than the low power ARM controller in an SSD. In other words, AES-NI is a set of extra software instructions that increase the speed of AES-encryption (or decryption) operations performed by the CPU.So having an AES-NI enabled CPU will increase the speed of all software encryption and decryption, compared to a CPU that performs AES as a generic mathematical operation. Jon and alwinston,So AES-NI is an extension to the x86 instruction set. There is to my knowledge only ONE way to clone a Bitlocker encrypted Win10 SSD to another one and have it still be encrypted, and that's using Casper Secure Disc 4.2 I couldn't find another option.
