In standard deviation, Seagate IronWolf posted its best read performance when configured in iSCSI with 464.47ms, while recording its best write performance in CIFS with 1,898.31. Prevention. Enjoy a seamless, superior NAS experience as IHM monitors your system environment and offers preventative actions to secure your data. The new Seagate IronWolf 12TB capacity is certainly a great addition to the company’s line of NAS, offering impressive performance while promoting total cost of ownership. With this massive 12TB model, the new IronWolf capacity helps organizations who want the smallest physical footprint per TB as possible. To further its compatibility NAS environments, Seagate has optimized IronWolf line with AgileArray and is built with dual-plane balancing and RAID optimization in multi-bay environments. This HDD is also designed to thrive under 24/7 operation, featuring a workload rate of 180TB per year with an MTBF of 1 million hours.

Drive balance with Rotational Vibration (RV) sensors - manages multi-bay vibration for long-term consistent performance and reliability RAID performance optimized - maximizes responsiveness and uptime with NAS-aware Error Recovery Control The IronWolf 12TB was only slightly slower than its Barracuda cousin in our copy tests. The ES.2 shows the kind of slow sustained performance many users are used to.

Compare

In the following section of this review, we will test 8 Seagate IronWolf 12TB HDDs performance in both iSCSI and CIFS configurations inside a Netgear 628x (RAID6). Results of iSCSI 4k average latency were more or less that same, with the IronWolf just behind its Pro brethren at 392.454ms while reads hit an average of 428.802ms. CIFS connectivity showed similar write performance (433.843ms), though read activity was more than double the latency (820.944ms).

Note that we did not spot any statistically relevant difference in the seek times between the BarraCuda Pro and the IronWolf. Capacity caveats Recovery. In the event of failure, rely on a secure environment for data recovery with Seagate® Rescue Data Recovery Service (2-year service included with IronWolf Pro).

Pricing, Warranty & Endurance Seagate's IronWolf comes in eight different capacities, and that's not counting the IronWolf Pro lineup. Seagate only uses helium with the two highest capacities, while the 6TB to 12TB models are the only drives with a 7,200-RPM spindle speed. Those models also have the best UBER (uncorrectable bit error) rating. Rotational vibration (RV) sensors are the biggest dividing line for the IronWolf series. The 3TB, 2TB, and 1TB drives don't come with RV sensors, which can hamper performance in a large array. Looking at standard deviation, the IronWolf showed its best performance in the endunder CIFS connectivity with a solid 384.04ms (which was second place, just behind its Pro brethren); however, iSCSI showed much better burst performance with 20.97ms (vs. CIFS’s 61.15ms). The IronWolf continued it great RAID6 iSCSI performance in average latency, posting a range of 9.07ms through 394.62ms. The next best drive was the Pro version of the Seagate line, posting 403.45ms.

As far as CrystalDiskMark 5 is concerned, the IronWolf and BarraCuda Pro might as well be the same drive. IronWolf Health Management in compatible NAS systems continuously helps to safeguard the health of your data We're focusing on the 12TB IronWolf, but the 10TB model tags along for the review. Both share the same performance specifications. The four high-capacity 7,200-RPM models provide 210 MB/s of throughput. The remaining four drives deliver 180 MB/s of throughput due to their 5,400-RPM spindle speeds. Features Seagate's AgileArray technology is a suite of features designed to provide a better user experience. Here's how the company describes the features:

Enjoy peace of mind with 3 years Data recovery

It’s always exciting to see Seagate release a new product on the NAS market, as their previous releases have always been well-received, including the 10TB IronWolf model we reviewed almost a year ago. As such, 12TB IronWolf is the company’s highest capacity, performance-driven NAS HDD to date. Designed to excel in always on, always accessible 24/7 storage servers, the new IronWolf allows businesses to get the most out of their storage devices while being optimized for NAS environments with AgileArray, Seagate’s specific set of hardware, firmware and software features that promote the best possible NAS experience. The IronWolf HDD family is also equipped with dual-plane balancing and RAID optimization in multi-bay environments and offers enterprises with highly efficient and advanced power management capabilities. This article sounds like an apology to why Seagate's trust should be restored. If the 8Tb drives failed in a short amount of time, the similar products with bigger space might just do the same thing. Changing the segment name to make us think those products won't fail again is just a frivolous marketing stunt. There are too many problems with Seagate's drives: predictive failures that happen a few weeks later, the platters are bad quality, firmwares that are often buggy, and probably planned obsolescence, are just enough redflags as to why this company is not serious enough to stay in that business' segment.
