The graphs show the average of 5 cycles of random transfers ranging in size from 4K to 1024K. QuickBench's Standard Test was used to measure small random file transfer performance. Test 'mule' was a 2011 iMac 3.4GHz Core i7 running OS X Lion 10.7.2. LBD NoteHD = LaCie Little Big Disk Thunderbolt enclosure (two 500G Hitachi Travelstar HDDs in RAID 0 mode) PR4 NoteHD = Promise Pegasus R4 Thunderbolt RAID enclosure (two 500G Hitachi Travelstar HDDs in RAID 0 mode) LBD Hybrid = LaCie Little Big Disk Thunderbolt enclosure (two 500G Seagate Momentus XT Solid State Hybrid HDDs in RAID 0 mode) PR4 Hybrid = Promise Pegasus R4 Thunderbolt RAID enclosure (two 500G Seagate Momentus XT Solid State Hybrid HDDs in RAID 0 mode) LBD 6Gssd = LaCie Little Big Disk Thunderbolt enclosure (two 120G OCZ Vertex3 Max IOPS 6Gb/s SSDs in RAID 0 mode) PR4 6Gssd = Promise Pegasus R4 Thunderbolt RAID enclosure (two 120G OCZ Vertex3 Max IOPS 6Gb/s SSDs in RAID 0 mode) Settings were 4.0GB File Size, 2048x1556 10-bit RGB Video Frame Size, 335 frames, file system cache disabled.

Then for perspective, we included two models of notebook hard disk drives (HDDs).ĪJA System Test was used to measure how fast you can capture and playback HD video. To stress both enclosures to the limit, we used dual 6Gb/s solid state drives (SSDs).

We wanted to know if two striped drives in the LaCie Little Big Disk (LBD) Thunderbolt would transfer data as fast as the same two drives in the Promise Pegasus R4.
