Seagate IronWolf NAS SATA 6Gb/s NCQ 64MB Cache1 16TB

Product Information

There is one aspect to the IronWolf Pro 20TB that concerns us, and it’s the 300TB per year workload definition.

Should the drive fail after exceeding these workload limits, Seagate can reject warranty replacement accordingly. One surprise was that considering the performance improvements, we had expected the 20TB drive to pull more power and generate more heat.IronWolf Health Management in compatible NAS systems continuously helps to safeguard the health of your data Pet Habitats and Supplies, Apparel and Leashes, Training and Behavior Aids, Toys, Aquarium Supplies such as Pumps, Filters and Lights 15 Days Returnable Seagate brought its 20TB products to market alongside Western Digital, eliminating any special bragging rights on this scale of drive. 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.

Exos ® X16 Hard Drive Provides Solution for High Density Storage Supporting Accelerated Hyperscale Demand and IronWolf 16TB Delivers Highest Capacity for NAS 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

The standard deviation latency results, the 16TB IronWolf Pro 720.78ms (CIFS) and 584.24ms (iSCSI) in the terminal queue depths.

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. 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. 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. Talking about the outside of the Seagate IronWolf Pro 20TB is mainly irrelevant. Externally, it appears to be identical to every other Seagate IronWolf drive in the 3.5-inch form factor. 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

With 4k max latency, the 16TB IronWolf Pro showed 4,896ms and 16,962ms in iSCSI reads and writes, respectively (again behind the 14TB model). In CIFS, the 16TB Pro hit 11,062ms read (last) and 16,273ms (2nd) write. 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. 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. Desktops, Monitors, Pen drives, Hard drives, Memory cards, Computer accessories, Graphic cards, CPU, Power supplies, Motherboards, Cooling devices, TV cards & Computing Components 15 Days Returnable Like the models before it, the IronWolf Pro 16TB is NAS-optimized with AgileArray, a technology that enables dual-plane balancing and RAID optimization in multi-bay environments as well as RV sensors to maintain high performance in multi-drive NAS enclosures. It also allows for advanced power management. In addition, the 16TB Pro is the embedded IronWolf Health Management software application, which provides monitoring, intervention, and data recovery options to further help keep user data safe and secure.

The features go beyond the specification sheet. For instance, Seagate attaches the spindle to both the top and bottom of the case to improve stability. The drives also support the ATA-8 streaming command set for increased performance with large sequential transfers. The technology allows the IronWolf to handle up to 64 data streams simultaneously.But, the WD Red Pro 20TB that’s in direct competition with the Seagate IronWolf Pro 20TB is much cheaper, at least at the MSRP level. 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. We should mention that this definition of workload isn’t unique to Seagate, it’s the same for Western Digital drives, and their workload amounts aren’t different for the Red Pro 20TB. 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.
