Excerpt: I use this product to back up large photo files on my Mac book Pro and transfer those files to my desktop Mac Pro. The MacBook Pro is the new model with USB3 and Thunderbolt connections, my desktop mac pro is an older model with FireWire 800.
Excerpt: The bad: USB 3.0 is not as fast as it seems on paper. Especially when backing up 250GB+ of data, which takes 2 hours to complete backup and it significantly reduces the computer speed/capacity to complete a task, clearly demonstrated when using Parallels 9 and 10 and or graphics application/s.
Excerpt: I used these external drives to copy four other drives onto one LaCie and then copied the first drive to the second as a safety. I paid more for the thunderbolt which is the fastest connection I have in my mac, because I didn't want my computer running for hours on this process.
Summary: This is the third one of these I have bought over the last year . . . they work perfectly. Very high speed transfer rate for data back-up. I like that it is bus powered, compact and easy to carry around.

Summary: More room than I need and that makes me feel comfortable. It might be my ports on my computer or the cable itself, but this hard drive will disconnect from time to time from my mac book with just a little touch of the chord. Any one have any solutions to that?
