Western Digital Red 4TB HDD RAID Report

By: Tyler Bernath | RAID in Storage | Posted: Apr 23, 2014 2:04 pm

Final Thoughts




Well there we have it; the WD Reds do perform quite well in RAID. At the drives' peak, we measured close to 550 MB/s read at QD32 in our four-drive RAID 0 array. With RAID 5, we achieved a peak rate of 400 MB/s, which was on par with the three-drive RAID 0. As far as write performance went, we had a peak rate just over 400 MB/s with our four-drive RAID 0, while RAID 5 was closer to 375 MB/s.


Read response times for the WD Reds were at their best with RAID 10, but not far behind was the four-drive RAID 0 array, and even RAID 5 was knocking on the door as well. Over with write response times, we found the single-drive configuration to have the highest response time, next to the RAID 5 array. The best times were found with the four-drive RAID 0 and three-drive RAID 0 arrays.


Power Consumption of four drives came in around 22.2 watts at its peak during sequential testing, while random came in at 18 watts. Three drives consumed 17 watts during sequential workloads and just under 14 watts with random. Single and our two-drive RAID 0 came in at 6 watts and 11.5 watts.


In closing, I will say that the Reds are a great drive for those of you wanting to build storage servers, or just want to run a few drives in RAID for the increased performance or redundancy. Power consumption of the Reds is next to reliability with these drives being the most efficient on the market. If you want to see more hard drive RAID reviews, please do let me know; I do, however, have a few 4TB Seagate NAS drives that I will be testing, so you can look forward to that in the coming months.
