    I have a mbpro 2010 with a 320 gb large iphoto library.

    I want to copy it to my sansung 500 gb ssd evo disk in my mac mini 2012 (quad core 2.6)
    Only drive, I have remowed the 1 tb drive.

    Whats the fastest and safest way to transfer that large file?

    The fastest way is to break it down into smaller chunks and copy those. Try 60-70 GB at a time. That will be faster than copying 320 GB with one copy command.

    Regarding safety, you should already have those files backed up. If you don't have a backup, you're begging to lose those photos.

    Target Disk Mode

    Boot the MacBook into TDM, then plug it into the mini via a FireWire cable.

    I'll second using Target Disk Mode. That's exactly what it's for.

    I've done a lot of this type of thing.

    Gigabit Ethernet is by far the fastest method for copying files among those two computers. Just set up file sharing between the two computers (, and hook them up with an Ethernet cable (assuming they aren't already wired to the same network).

    If you don't have an Ethernet cable, then second fastest would be Firewire 800 via Target Disk Mode as others have suggested.

    If you don't have an Ethernet nor a Firewire 800 cable, then third best would probably be file sharing over Wi-Fi if you have an 802.11N wireless router and a decent connection to both computers.

    Probably dead last would be copying it from the laptop to an external drive, and then copying it all again from the external drive to the Mini. I've had to do that a couple of times, and it's something you set up to do overnight.

    I've also noticed a substantial difference between, say, a files that add up to 500GB vs thousands of files that add up to the same size. Even though it's the same size, transferring that many files can take several times as long as just a few files of the same total size. I'm not familiar with iPhoto library file structure, but if it's thousands of files, I'd ZIP the whole thing first and transfer the ZIP file. Especially over a slow connection, this could save hours.
