Best Uses

    I use this drive primarily as my mirrored backup drive for my iMac with 3TB storage. At present, I have over 1.5TB of data on the computer. Utilizing the iMac's new Thunderbolt port, the computer backs up to the LaCie 2big 4TB in about 15 minutes using SuperDuper backup software.

    The drive is generally quiet except when it wakes at backup time. Its "purr" is loud enough to be heard from the other side of my office. It's not a major problem, but my wife keeps thinking it's the cat.

    The drive is built like a tank. Though I appreciate its solid construction, I wish it were smaller, not because it takes up that much space, but because it commands a certain presence on my desk; Frankly, I'm not that interested in showing off my backup drive. For comparison, it's about 25% taller than my 2TB OWC Mercury Elite-AL Pro RAID and a half-inch wider.

    My biggest complaint about the drive is its signature LaCie big blue power button on the front. It feels dated and corny, but mostly it's glowing all the time that it's on. Because of its size and strength, it can be visually distracting. I've had to turn the front of the drive away from me on the desk, so that it does not shine toward me while I'm working.

    All in all, it's a great drive with the quality LaCie name behind it. The cost is also half as much as some other comparable Thunderbolt RAID solutions out there which is a big plus. The cons list is short and insignificant. If you're looking for a great Thunderbolt RAID solution, this is it.
