When Seagate launched the Barracuda Pro in late July, they also launched and rebranded their entire lineup of HDD solutions. The Surveillance drive became the Skyhawk, SSHD is now FireCuda, and the NAS HDD is now called IronWolf.

With the rebranding comes a new 10TB Helium solution for both the SkyHawk and IronWolf lineups, and with the latter in house today, we are going to run it through some testing. The IronWolf takes advantage of a number of technologies that increase reliability in multiple drive arrays including AgileArray, a multi-part system that includes the likes of AccuTrack that gives tolerance for vibration in multi-bay environments along with rotational vibration sensors and dual-plane balancing.

Taking a closer look at the specification sheet above, the IronWolf uses the VN identifier whereas the Barracuda Pro used DM as its identifier. The interface is SATA 6Gb/s, and this solution is ready for one to eight bay systems and 180TB/Yr. Sustained performance is said to be around 210 MB/s with a 7200RPM spindle speed and 256MB cache.

Load/Unload cycles sit at 600K with a MTBF of one million hours. Power starts with a typical current of 1.8A and 6.8 watts, and down to 4.4 watts at idle and 0.8 watts in sleep. MSRP of the 10TB Seagate IronWolf comes in at $469.99 with a three-year warranty.

Pulling off the PCB, we have an Avago branded controller in the center with a Smooth motor at the top. 256MB of cache comes from Winbond.

Benchmarks - Test System Setup and ATTO Benchmarks

Tyler's Test System Specifications

ATTO - Baseline Performance

Version and / or Patch Used: 2.34

Seagate IronWolf 10TB NAS HDD Review 20 | TweakTown.com

We start off testing, just as we did with the Barracuda Pro. ATTO is a standard for performance testing and in read the IronWolf was a touch under the 'Cuda Pro, hovering at 220 MB/s from 64 to 8M transfer sizes.

Seagate IronWolf 10TB NAS HDD Review 21 | TweakTown.com

Write performance started around 64kb transfer size with a hair over 200 MB/s and it finished up at a touch over 220 MB/s.

Benchmarks – 4K Random Performance & Latency

IOMeter – 4K Random Performance with QD

Seagate IronWolf 10TB NAS HDD Review 22 | TweakTown.com

Read IOPS start all four of our drives under test around 160. As we move higher into QD, the drives start to separate, where the IronWolf becomes the quickest drive at QD16.

Seagate IronWolf 10TB NAS HDD Review 23 | TweakTown.com

Write IOPS were off to a quick start with the IronWolf pulling in a hair under 600 IOPS at QD1 and 575 IOPS at QD32.

Seagate IronWolf 10TB NAS HDD Review 24 | TweakTown.com

The latency results had the IronWolf show a consistent step with the Enterprise Capacity and 'Cuda Pro.

Seagate IronWolf 10TB NAS HDD Review 25 | TweakTown.com

Write latency too was consistent from a few ms at QD1 to 57ms at QD32.

Benchmarks – Sequential Performance & Latency

IOMeter – Sequential Performance with QD

Seagate IronWolf 10TB NAS HDD Review 26 | TweakTown.com

Sequential performance for the IronWolf started out at 190 MB/s at QD1 and ramped to a peak of 225 MB/s at QD32.

Seagate IronWolf 10TB NAS HDD Review 27 | TweakTown.com

As for write performance, QD1 showed solid performance at 210 MB/s, while moving through to QD32 the IronWolf produced 200 MB/s.

Seagate IronWolf 10TB NAS HDD Review 28 | TweakTown.com

Read latency put the IronWolf a touch below the Enterprise Capacity.

Seagate IronWolf 10TB NAS HDD Review 29 | TweakTown.com

Write latency was the highest of the three Seagate solutions.

Benchmarks – Workloads

IOMeter – Workload Performance with QD

Seagate IronWolf 10TB NAS HDD Review 30 | TweakTown.com

Database started off with nearly 175 IOPS at QD1 and finished at QD32 with 300 IOPS.

Seagate IronWolf 10TB NAS HDD Review 31 | TweakTown.com

File Server showed similar performance at QD1 with all drives, while at QD32, the IronWolf was a touch above the EnCap at 330 IOPS.

Seagate IronWolf 10TB NAS HDD Review 32 | TweakTown.com

Email Server proved to be one of harder workloads for the IronWolf, starting out at 190 IOPS at QD1 and ending with 300 IOPS at QD32.

Seagate IronWolf 10TB NAS HDD Review 33 | TweakTown.com

Web Server had all the drives up and running again starting near 150 IOPS and ending at 500 IOPS; the IronWolf did quite well in this workload.

Seagate IronWolf 10TB NAS HDD Review 34 | TweakTown.com

Workstation peaked just over 300 IOPS for the IronWolf.

Latency with QD

Seagate IronWolf 10TB NAS HDD Review 35 | TweakTown.com

Diving into the response times of Workloads testing, Database reached a peak of 110ms at QD32.

Seagate IronWolf 10TB NAS HDD Review 36 | TweakTown.com

File Server touched a high of 90ms after starting out around 8ms at QD1.

Seagate IronWolf 10TB NAS HDD Review 37 | TweakTown.com

Email Server for the IronWolf hit 105ms at QD32, slightly lower than the EnCap 10TB.

Seagate IronWolf 10TB NAS HDD Review 38 | TweakTown.com

Web Server, being one of the best workloads for the Seagate solutions, the IronWolf had a low 8ms starting point and reached 63ms at its peak.

Seagate IronWolf 10TB NAS HDD Review 39 | TweakTown.com

Workstation ended at 103ms at QD32 about 95ms higher than where it started at 8ms QD1.

Power Consumption and Final Thoughts

Power Consumption

Our custom power testing samples each drive for a period of three minutes, across each workload. In order to offer more granularity, we sample the power in one-second intervals.

Seagate IronWolf 10TB NAS HDD Review 40 | TweakTown.com

With the launch of the 10TB helium based solution, Seagate has ramped up their performance per watt.

The IronWolf falls perfectly into line with this as it uses slightly less power in random read and write (around 5.5 watts) while moving to sequential workloads power switches between 6.5 and 7 watts.

Final Thoughts

The IronWolf in its 10TB configuration brings a solid jump in capacity over previous 8TB NAS solutions. For those running multiple bay configurations, this means an extra 4TB for two bay users and 8TB for four bay users. A high-level of build quality is certainly present with this solution; I actually had four drives in house during testing, and I found solid consistency and no drive failures - and that was after a lot of end to end testing.

The performance wasn't quite as high as the Barracuda Pro, but it was certainly admirable, especially in sequential and random workloads. Peak performance for sequential came in at 220 MB/s read and 200 MB/s write while IOPS topped at 610 read and 550 write. In enterprise workloads, the IronWolf was right with the 'Cuda, hitting 300 IOPs in Database and Email Server, while File Server topped 350 IOPs, and Web Server was by far the best at 500 IOPS.

Overall, the capacity increase alone is going to be enough for most to jump on this solution, but for those that need a bit more encouragement, Seagate is offering a solid amount of technology in this solution with AgileArray, and its 180TB per year rating is one of the highest on the market.

Growing up in a small farm town, tech wasn't around, unless it was in a tractor. At an early age, Tyler's parents brought home their first PC. Tyler was hooked and learned what it meant to format a HDD, spending many nights reinstalling Windows 95. Tyler's love and enthusiast nature always kept his PC nearby. Eager to get deeper into tech, he started reviewing.
