Final Thoughts


As we mentioned in the beginning of the review, the 12TB model didn't appear to use anymore power than the 10TB, according to the specifications. Looking at the raw data from my own testing I do see a touch more being used in random read and random write is much more stable than the 10TB, which gets a bit erratic from here. Moving through random write we maintain around 5.6 watts and then we see a transition period between random and sequential where the drive is using around 6 watts and then full sequential at 7.1 to 7.3 watts.

So overall, we still have the same reliability as the previous 8 and 10TB models with Agile-Array and RV sensors to watch the drive. Using this solution in a compatible NAS system will get you access to 200 measurements of the drives health with IHM and power requirements haven't changed any if at all. For those upgrading from 10TB drives in a four-bay platform that's an additional 6TB of capacity in a RAID 5 or 4TB in RAID 6 with no additional cost in power requirements.

The 12TB model offered a good amount of performance improvements over the 10TB in most of my testing. ATTO improved substantially at lower file sizes whereas the 10TB was non-existent and at 4K and higher we saw some marginal improvements of 10-15 MB/s. Random read and write showed a solid 100 IOPs advantage to the new 12TB solution and Sequential workloads enjoyed a 25 MB/s advantage over the previous 10TB IronWolf. Mixed workloads averaged a 75-100 IOP advantage moving to the 12TB solution.


The current market for 12TB drives is quite interesting. Seagate is heavily dominating this space with three models available at the time of this writing. WD does have 12TB solutions in the Gold but realistically it's not comparable to the IronWolf or Barracuda platform at all. With that said, Seagate has a solid drive with the 12TB IronWolf, it offers a performance and power advantage over previous 10TB solutions and even more so if you are still using 4 or 6TB solutions.

The Bottom Line: The Seagate IronWolf offers class leading performance and capacity while offering a feature rich platform for NAS users wanting reliability.
