Drobo 5C Five-Bay USB-C DAS Review

Final Thoughts


It has been awhile since I used a Drobo appliance, a little over three years since my last review of the 5D. It's nice to see in that time Drobo has stayed true and still delivers the same quality I felt back then. The 5C is a solid unit, a desktop tank especially with drives installed. It is also very quiet for its size and with the USB-C connection, easy to setup and use.



Performance isn't the highest I have seen with USB-C, then again there is no RAID 0 with Drobo. You buy a device like this for data security. We were able to reach 250 MB/s read and write with our Phison SSDs and 220 MB/s read and write with our Toshiba HDDs. IOMeter was a bit harder on the Drobo limiting sequential to 150 MB/s read and 140 MB/s write with SSDs and 150 MB/s read and 135 MB/s write with HDDs.


Workload performance topped 650 IOPs with SSDs followed by 720 IOPs in File Server. That same level of performance was seen through the rest of our workloads and transitioned over to response times where we saw some solid performance from the SSDs at QD128 and the HDDs did well up to QD32.


The Drobo Dashboard hasn't changed too much over the years and thus was very comfortable and easy to navigate. Switching from single to dual drive redundancy is as easy as clicking a box and the resync process is rather quick compared to a RAID rebuild.


Overall, I like the Drobo 5C. It's not much of an upgrade if you have a 5D or 5Dt, but for those new to this market, it provides is a solid first step to securing your data.
