    Hi,

    I'm about to install Sonnet Tempo SSD PCI card into my MacPro running Parallels.

    Parallels will be streaming Audio Samples from the Sonnet. Will the reads be significantly slower due to Parallels?

    ps: The reason i don't just run in bootcamp, is because of the fan noise (osx fan management is n ot present when running WIN7 via bootcamp.)

    thanks in advance,

    best,
    SvK

    Doesn't have to be. Not sure about Parallels but most virtual machines have a way to mount a "raw"/"native" unshared device to the hosted OS. If the card was a native NTFS file system that the OS mounts the drop off would be negligible. (Assuming Parallels has enough resources to run smoothly independent of that disk and have modern VTx support in the CPU. )

    If the Windows "disk" accessing is really a Mac HFS+ file then the overhead is likely tolerable but higher. (again assuming there isn't significant other stuff running in OS X that is hogging resources. )


    lack of drivers ? Is this a relatively standard Apple configuration?

    Unless your using 3rd party software, OS X does not control the fan speeds, the SMC does. :)

    But yes, virtualisation slows down (only a little bit) read/writes to connected drives (atleast VMWare does).
