LaCie has been known to give its tech products a touch of fashion, and the 2big Thunderbolt Series is no exception.
The device looks good and sturdy, resembling the rest of the 2big family, including the already reviewed 2big USB 3.0.
The biggest difference from the previous models is that it has two Thunderbolt ports on the back that take the place of any other connection types, so no USB, FireWire, or eSATA.
The drive also now comes with two hard drives of up to 3TB each, for a total capacity of 6TB in RAID 0 (or 3TB in RAID 1). You can replace these hard drives by yourself, but note that doing so will void the warranty.
In my testing the 2big Thunderbolt, being the first dual-bay Thunderbolt drive, proved to be the fastest dual-bay external hard drive on the market. It was, however, noticeably slower than other Thunderbolt devices I've worked with, such as the Pegasus R6.
Still, since the Thunderbolt standard is so much faster than even the fastest internal drive, this "slow" performance actually means the 2big Thunderbolt is about as fast as you can currently take advantage of from an external storage device.
That fact plus much friendlier pricing than usual, at $650 for the 4TB or $800 for the 6TB, make the 2big Thunderbolt a good choice for any owner of a Thunderbolt-enabled Mac.
