I met with LaCie this morning to talk about its upcoming Little Big Disk Thunderbolt storage solution. Unlike the Promise Pegasus R4/R6, the Little Big Disk only accommodates two 2.5" drives. LaCie will be offering both HDD and SSD options, although capacities will top out at 2TB for the HDD version and something much smaller for the SSD version.

The front of the chassis features a blue orb that lights up during disk accesses. It'll glow red if there's a problem with the setup. The orb also doubles as a power switch. There's no internal RAID controller, the drives rely on software RAID through OS X and by default will be configured as a RAID-0. 

Although Thunderbolt can deliver up to 10W, the controller, cable and drives together end up exceeding that limit so LaCie will be bundling an external AC adapter with the Little Big Disk. Around back there are two Thunderbolt ports that allow you to daisy chain up to six of these Little Big Disks. 

LaCie will be shipping the LBD this quarter. Pricing is TBD but we're eagerly awaiting our chance to review the chassis.
