    Just out of curiosity, what happens when you use a small process buffer.

    If it's no help go back to your original settings.


    That's a hard drive "Use" meter, it's not unusual what you're seeing. When you start Logic it grab's the audio off the drive filling the buffers, this causes a spike in the drive use meter.


    What's not normal is your comment: " It either just doesnt work or it leaves me with and audio block full of white noise."  This should not happen.

    It's not really a "clip" meter, think of it as a hard drive access meter or hard drive use meter. What would be a sign of very heavy use is if it ran constantly red, then you might see some problems related to pulling all of the audio data off on time. A blip into the red is completely normal.


    The "white noise" or "not working" problem was probably related to the operating system writing swap files to the same drive the audio was on, moving the project fixed that... I think you're ok. Go back to your original setting in Preferences/Audio.

    In case this was missed, as no one directly commented about your settings...


    Assuming you are running Logic 9.x as I didn't see it mentioned specifically by the OP......


    As you have 16GB of RAM you should run Logic in 64bit mode to properly benefit from that extra memory.


    Otherwise you are limiting Logic to roughly 1.8GB  of usable RAM once Logic is loaded and all the various overheads have been taken into account.


    Also, if you are using Kontakt, make sure you then turn off Kontakt's memory server (See Kontakt's Preferences) as it is no longer needed when running Logic in 64bit mode...

    Quit Logic, now select the Logic program icon, press command-I and the info about Logic will pop up, here you will get the option to have 32 bit selected, if it ain't you're in 64 bit mode. Hope that's clear!

    Are you running Logic in 64 bit?

    Just a thought...


    At this stage it may be worth checking the actual speed of your Thunderbolt external drive. Whilst the Thunderbolt interface should be capable of super high data rates, the drive itself may not.


    As a free and quick method:
