Above, we have the results of our single client workload (NASPT). With the Drobo 5D, your data is never not protected. Because of this, there is no option for any equivalent to RAID 0. As such, we tested the Drobo 5D in BeyondRAID single drive redundancy mode to garner the most performance from the unit.
In our single client testing, you can see the 5D did quite well. File copy from the NAS came in at 129 MB/s with to the NAS at 48 MB/s. Video playback and record was very impressive throughout with speeds topping 150 MB/s.
Random and Sequential Workloads
Our 4K Random read/write workload consists of sixteen threads all at QD16, results our measured in IOPS (Input Output Operations per Second). Above we find the 5D capable of 613 write IOPS and 142 read IOPS.
Our Sequential read/write workload is centered on 1MB transfer sizes again with 16 threads and a Queue Depth of 16. Here we find the 5D capable of 114 write IOPS and 64 read IOPS.
As you may have noticed, we don't have comparable units in our chart at this time, but keep an eye out as we have a few more appliances from LaCie and WD in house that share the Thunderbolt interface.
