Space–Saving Versatility
Designed by Neil Poulton with a sturdy aluminum body, the
LaCie 2big USB 3.0 easily integrates into any Mac or PC
environment. With upright, horizontal, stacked or rack-mounted
configuration options, the 2big USB 3.0 offers significant space–

Power Savings
The unique, fanless aluminum heat sink design has 60%
more surface area, which provides the most efficient heat
dissipation, keeps it ultra-quiet, and protects the hard
disk. The LaCie 2big USB 3.0 helps you to reduce power
consumption by switching to idle mode after a determined
inactivity time. You can schedule a deep sleep on/ off mode
according your needs, and the 2big USB 3.0 can be switched
back to operating mode from the client side.

*Maximum interface transfer rate = theoretical bus bandwidth, whereas burst transfer rate = maximum drive speed.
Performance depends on the RAID mode selected and burst transfer rates vary from one computer to another and may vary
slightly from one drive to another. Average speed is usually lower depending on host configuration.
**1TB (Terabyte) = 1000GB. 1GB = 1,000,000,000 bytes. Total accessible capacity varies depending upon operating environment
(typically 5-10% less). Capacity varies depending upon RAID mode.
***Calculations are based on 1080i 60 (8-bit) for uncompressed HD video, NTSC DV 25 standard-definition 720x486, 29.97 fps
for digital video; and an estimation of Digital SLR resolution of 10 megapixels for RAW photos of 12MB. These calculations are only
estimations and may vary with the codec used.
Windows XP does not support hard drives with capacities greater than 2TB.
