    Hello,

    I have slow performance on my system with AES encryption.

    I hava only a copy rate of 120 MB/s between my very fast SSD and my AES encrypted RAID.

    General question: When the system use the AES CPU Feature, can I see it with the task "System"
    I see in the taskmonitor the task "system" use only 10% CPU.
    I run under Windows 7 x64 SP1

    The Performance Benchmark in VeraCrypt says: 2,5GB/s
    What it mean, GigaByte or GigaBit

    When I test it unencrypted, I have really fast copy speed between SSD and unencrypted RAID Volume, round 2400MB/s. I mean really 2400 Megabyte.

    Where is my problem?

    Thank you

    I solved my problem.
    It was the GData VirenScanner.

    There is a mini driver in there, that have problems with really fast diskdrive (M.2 NVMe SSD oder RAID Sets)
