LaCie (http://www.lacie.com) has released two new professional storage solutions — the LaCie d2 USB 3.0 and LaCie 2big USB 3.0. Thanks to the inclusion of 3TB hard drives and the performance of USB 3.0, LaCie’s 2big USB 3.0, now available in 6TB, purportedly achieves a 20% speed boost by reaching 306MB/s.

LaCie says that’s the fastest performance of any 2-bay RAID solution to-date. The d2 USB 3.0 also demonstrates a speed increase of 156MB/s with the inclusion of a 3TB hard drive. The LaCie 2big USB 3.0 6TB and LaCie d2 USB 3.0 3TB will be available worldwide, at the beginning of November. Pricing starts at US$349.
