LaCie 5Big Thunderbolt 10TB DAS Review

Benchmarks - Black Magic Design DST, Xbench and AJA System Test




Within Mac OS X 10.8.5 we used a 5GB file size with Black Magic Design DST. Above, we have the results with the 5Big Thunderbolt in RAID 0 - this is truly mind blowing as we haven't seen Thunderbolt stretch it legs like this until now.




RAID 1 results were pretty typical coming in at 219 MB/s read and 137 MB/s write.




In our Xbench testing we found yet another hint of the performance of the LaCie 5Big Thunderbolt and just Thunderbolt as an interface for storage solutions. If we take a look at the results, you will notice the 5Big really excels in uncached sequential write with 4K blocks at 1158 MB/s.




RAID 1 results were pretty similar in Xbench as we saw with Blackmagicdesign DST.




AJA System test is one of a few storage focused benchmarks for OS X. Here we have the 5Big Thunderbolt in RAID 0 streaming a 720p video file over 200 frames with read/write speed recorded for each frame.




Above, we have the same test run through with a 1080p video file over 200 frames. Notice we still have the same crash in throughput around frame 10-15, most likely due to the HDDs caching and the RAID overhead.




Above, we have the 720p test repeated with the 5Big in RAID 1. Notice how consistent this test run is compared to the heart monitor pace the RAID 0 was creating.




Again, with 1080p and RAID 1 this time around, the 5Big hold steady performance throughout the entire 200 frame series in writes.
