I need a new ext hard drive (boot + all applications and text based docs stored on it... video, music, photos are on separate drives). Choices are: Lacie 2TB Little Big Disk -- Thunderbolt version OR I put a WD Black in a USB 3 enclosure. Obviously the latter choice is half the cost but I'd pay double for 50-75% speed increase. I know Lacie hasn't been the most stellar company in the past though so thinking the roll your own option might be safest. Any one have actual experience with the Lacie here?
