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.

The biggest leap from USBfor a noise free thunderbolt solution
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. …

Important: Only use WD Caviar® GreenTM hard drive assemblies to replace the drives in your My Book Thunderbolt Duo device enclosure. Using any other hard drive assembly voids the warranty for your My Book Thunderbolt Duo.

Could I buy another one of these at a later date to double the capacity ?
- Asked by James G
Yes, in theory. You can add the second drive and set the two up as a Raid BUT you will need to tempo Yes, in theory. You can add the second drive and set the two up as a Raid BUT you will need to temporarily store all the files you've collected on the first drive somewhere else, since the process erases both drives. Just transferring the files could take hours and there are different flavours of Raid depending whether you need speed or security so it is worth reading up on it before you decide. In any case, why not just keep two separate drives? When the older one fails, as it eventually will, you'll then have to face other issues to recover your data. Better to keep two separate drives, IMHO, or buy two to begin with. …
