REVIEW: LaCie Little Big Disk
Originally posted Friday, April 18th, 2014 by rob-ART morgan, mad scientist
LaCie is shipping their Thunderbolt 2.0 version of the Little Big Disk. It's completely new inside the familiar 'finned' enclosure with dual PCIe solid state blades. We jumped at the opportunity to benchmark not just one, not just two, but THREE of them in a RAID 0 set. Check out the progression in transfer speed as we added a second and third drive -- each connected to a different Thunderbolt 2.0 bus.
LBD TB1 = LaCie Little Big Disk Thunderbolt 1 (two internal 6Gbps SATA 256G SSDs striped)
LBD TB2 = LaCie Little Big Disk Thunderbolt 2 (two internal 512G PCIe flash blades striped)
LBD TB2*2 = Two LaCie Little Big Disk Thunderbolt 2.0 (four internal 512G PCIe flash blades striped on two different Thunderbolt ports -- Bus 1 and 2)
LBD TB2*3 = Three LaCie Little Big Disk Thunderbolt 2.0 (six internal 512G PCIe flash blades striped on three different Thunderbolt ports -- Bus 0, 1 and 2)
All LBDs were connected to a 2013 Mac Pro MD878LL/A Desktop.
SIMULATED 4K VIDEO CAPTURE and PLAYBACK
We used AJA System Test to test file level sequential transfer speed of a 16GB test document. It also simulates capture and playback of a 4096x2160 10-bit RGB video. (HIGHEST number means FASTEST in Megabytes per Second.)
DIRECT I/O SEQUENTIAL TRANSFER
We used the Custom Sequential test in QuickBench to measure the 10 sustained 1GB transfers with 5 iterations. (HIGHEST number means FASTEST in Megabytes per Second.)

WHERE TO BUY THE LACIE LITTLE BIG DISK THUNDERBOLT 2
Order direct from LaCie. (At the time of this posting, they were in scarce supply so there was no 'click to buy.')
Eventually it will be available from Other World Computing and other resellers. Amazon still has the LaCie Little Big Disk Thunderbolt 1 (dual striped 256G SSDs) we tested.
