The Drobo 5N2 is not directly comparable to any other NAS I have tested due to the lack of iSCSI. In my conventional testing, I would use iSCSI to achieve the highest levels of performance from the appliance or the Drobo I used a mapped network drive.
Starting things off we have Intel NASPT, a staple of NAS testing for most. As you can see, I did test both redundancy modes and found very little performance hit to be taken. At the peak, this solution could hit 114 MB/s in playback with the lowest performance coming from File Copy to the NAS at 52 MB/s.
ATTO Disk Benchmark was up next and it gives us an idea of the sequential performance of the NAS. At the peak, we are seeing 118 MB/s read at 128K and write performance was steady at 117 MB/s from 256K through 1M.
NAS Performance Tester simply throws single large file sizes at the NAS to test performance with a large amount of data. As you can see above, read performance starts off a touch under 100 MB/s but quickly takes off reaching a peak of 114 MB/s. Write performance from the start is at 115 MB/s and hold that throughout the test.
Looking at dual redundancy, we have similar performance. Read start off at 87 MB/s reaching a peak of 112 MB/s while write starts at 117 MB/s and holds.
Last, we have a couple of charts for CrystalDiskMark. Read performance at QD1 hovers around 110 MB/s read and 93 MB/s write while QD32 increases that to 118 MB/s read and 117.5 MB/s write.
Dual redundancy doesn't affect the 5N2 much at all, results here were similar at 117 MB/s read and write.
