    About Thunderbolt

    Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices via one simple port and a cable that carries both DisplayPort and PCI Express data. And it’s standard on every Mac.

    PCI Express is the technology that links all the high-performance components in a Mac. And it’s built into Thunderbolt, which means you can get PCI Express speed outside the box.

    Thunderbolt gives you up to 10 Gbps in both directions, allowing for super-fast data transfer between peripherals. You also have enough bandwidth to daisy-chain multiple high-speed devices without using a hub or switch.

    Thunderbolt also provides double the power of USB 3.0, delivering 10 watts to peripherals for improved performance on the go.

    I'm a full time pro photographer and needed more storage. In the past I've used USB2 external drives and copying weddings at 25GB I'm a full time pro photographer and needed more storage. In the past I've used USB2 external drives and copying weddings at 25GB each from my imac took 15-25 minutes ... twice for two separate drives. This did it in 5 in total for both drives on a raid 1 setting.

    Theres no noticeable noise unlike the fan assisted thunderbolt docks which everyone seems to complain about. It comes with a cable and you can replace drives when they either break or when they are full.

    I had a little trouble with the software changing it from raid 0 to raid 1 but after I ejected the uninstaller it seemed to do it just fine. I'd buy another any day of the week.

    I got around 140-150mb read and write in Raid 1 and 290-300mb in Raid 0 if you're all techy and stuff (black magic disk thingy).

    Need external drives with Raid and Thunderbolt - just buy it.
