The latest capacity of the Seagate IronWolf Pro line is a solid addition to the company’s Guardian Series. This NAS-specific drive gives users the highest capacity possible at relatively inexpensive price tag, while results from our performance charts reaffirm that the line is a good choice for SOHO, SME markets and creative professionals. Though it has many of the same features as the non-Pro line, the IronWolf Pro offers some expanded specs including its support of up to a 24-bay storage device (compared to 8 bays for the non-Pro version) and 1.2 million hours MTBF (compared to 1 million MTBF for the non-Pro version). The next benchmark tests the drives under 100% read/write activity, but this time at 8k sequential throughput. In iSCSI, the 16TB IronWolf Pro hit 128,123 IOPS read and 55,688 IOPS write, while CIFS saw half the IOPS in read performance with 62,165 coupled with 43,612 IOPS write In the following section of this review, we will show the 16TB Seagate IronWolf’s performance in both iSCSI and CIFS configurations and will compare them to other IronWolf models. Seagate supplied StorageReview with 8 samples of their new NAS HDDs, which we configured in RAID6. All the drives were tested in our NETGEAR ReadyNas 628X.

But working the maths a little, taking 300TB and multiplying that by the five years of warranty yields an operational guaranteed limit of 1500TB. Divide that by the capacity, and the total bytes transferred is only 75TB per TB of capacity. Overall, the Seagate IronWolf Pro 16TB NAS HDD is a reliable NAS drive that features great performance in specific configurations, while its massive capacity gives users the (budget-friendly) flexibility they need to grow as their data requirements expand. The IronWolf Pro is available in a wide range of other capacities, including 14TB,12TB, 10TB, 8TB, 6TB, 4TB, and 2TB. This allows the IronWolf Pro to fit into pretty much any organization’s or creative professional’s budget, which adds a ton of flexibility. In addition to its 5-year limited warranty, the IronWolf Pro line comes with a 2-year subscription to the company’s Rescue Data Recovery plan, a service that provides data recovery from mechanical, accidental, or natural disaster incidents. Seagate IronWolf Pro 16TB NAS HDD Specifications Standard Model Number This design is exclusively a SATA 6GB/s connected drive, and can be used in any PC or NAS that accepts SATA drives of that spec. The IronWolf Pro is an NAS family of HDDs designed for 24×7 performance in a multi-drive environment. For this review, we will be looking at the new 16TB model, which expands on the 14GB Pro from earlier this year. This makes for a whopping 384TB inside an 24-bay NAS, allowing users to store a huge amount of data without having to add any expansion units. This is certainly great for creative professionals, SOHO users and all types of growing businesses that work with large datasets, as it offers them a more cost-effective way to scale as data requirements grow. The Seagate IronWolf line features the usual 6Gb/s SATA interface, 7200rpm spindle speed and 1.2 million hours MTBF.

CrystalDiskMark: 286.8MBps (read); 279.3MBps (write) Atto: 277.89MBps (read, 256MB); 274.68MBps (write, 256MB)

The previous 18TB IronWolf Pro could read and write sequentially at about 260MB/s, and the 20TB achieved more than 285MB/s in most tests. That’s nearly a 10% improvement, almost the same margin as the increase in capacity. Prevention. Enjoy a seamless, superior NAS experience as IHM monitors your system environment and offers preventative actions to secure 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 I also read the article twice, there are a bunch of affirmations that I completely disagree with, it's not even a different point of view, it's just a point of view based of presenting a situation and a reality in a given time (example Seagate increased product quality, but prices also shot up). It's always the same thing, prices go up to get the executives bigger bonuses, nothing else. That being said, there are fortunately other competitors in the market.If you are reading this review and are already bored with the numbers, we apologise in advance. Because this drive is all about the numbers, the good, bad and ugly. What we see here is the reality of technology with moving parts, where each operation the drive performs contributes to its ultimate failure, much like the playing of a vinyl record. Should the drive fail after exceeding these workload limits, Seagate can reject warranty replacement accordingly. It comes with 256MB of cache, a five-year warranty and three years of Rescue Data Recovery Services. MTBF (Mean Time Between Failure) is 1.2 million hours, and the yearly workload is 300TB.

Therefore, where an SSD only considers writes in its TBW, this workload includes reads in addition to writes as part of the rate, disturbingly. In standard deviation, the 16TB IronWolf Pro showed reads and writes of 619.791ms and 1335.448ms in iSCSI, respectively, and 53.92ms and 1746.24ms in CIFS. Oddly, while idle, the 20TB pulls a little more power than the 18TB, 5.5W from 5.2W, but critically when it is running, it uses less power. Down from 8W on the 18TB to 7.7W on the 20TB, its standby power level is also less.

Looking at our throughput test which measures 4k random performance, the 16TB IronWolf Pro fell behind in iSCSI performance with 853 IOPS write and 527 IOPS read, as it was out performed by the 14TB model. In CIFS, the 16TB IronWolf Pro posted 683 IOPS write and an impressive 4,774 IOPS read. Alongside its IronWolf Pro, Seagate also makes a 20TB EXOS design that we’ll be covering shortly, aimed at the same slice of the Enterprise market that the UltraStar DC HC560 was created.

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.Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. These profiles have been developed to make it easier to compare to our past benchmarks, as well as widely-published values such as max 4K read and write speed and 8K 70/30, which is commonly used for enterprise drives. Our next test shifts focus from a pure 8k sequential 100% read/write scenario to a mixed 8k 70/30 workload. This will demonstrate how performance scales in a setting from 2T/2Q up to 16T/16Q. In CIFS, the 16TB IronWolf Pro started at 582 IOPS while ending at a leading 1,415 IOPS in the terminal queue depths. In iSCSI, we saw a range of 395 IOPS to 571 IOPS.
