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. 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. Therefore, where an SSD only considers writes in its TBW, this workload includes reads in addition to writes as part of the rate, disturbingly. One surprise was that considering the performance improvements, we had expected the 20TB drive to pull more power and generate more heat.

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 Pet Habitats and Supplies, Apparel and Leashes, Training and Behavior Aids, Toys, Aquarium Supplies such as Pumps, Filters and Lights 15 Days Returnable Prevention.

Externally, it appears to be identical to every other Seagate IronWolf drive in the 3.5-inch form factor. In max latency, the 16TB IronWolf Pro posted a range of 1,424.4ms to 11,171.2ms in CIFS, while iSCSI showed 3,229.25ms through 7,665.47ms in the terminal queue depths. That’s a worse workload than the cheapest unbranded SSD available. But it is even less impressive when you realise that Seagate defines the workload as “Annualized Workload Rate = (Lifetime Writes + Lifetime Reads) * (8760 / Lifetime Power On Hours)”

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. 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.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. 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. 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.

Should the drive fail after exceeding these workload limits, Seagate can reject warranty replacement accordingly. CrystalDiskMark: 286.8MBps (read); 279.3MBps (write) Atto: 277.89MBps (read, 256MB); 274.68MBps (write, 256MB)

The standard deviation latency results, the 16TB IronWolf Pro 720.78ms (CIFS) and 584.24ms (iSCSI) in the terminal queue depths. With average latency at 8k 70/30, the 16TB IronWolf Pro showed a range of 10.1ms through 447.9ms in iSCSI, while CIFS showed a range of 6.84ms through 179.93 in CIFS, the latter which was again the best-performing configuration.

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). 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. 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. 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.
