As always, with our storage reviews, before we move on to the benchmark results, let us briefly discuss the physical attributes of this hard disk drive first. The IronWolf Pro ST12000NE0007 12TB is your quintessential 3.5" hard drive from Seagate; the top of the drive is bare metal with a dull silver finish, and a large label placed across the middle. That said, the label has been updated to reflect Seagate's latest product branding, and the addition of color graphics make everything all the better. It is also nice to see the return of unique names, including IronWolf for NAS HDDs, FireCuda for SSHDs, BarraCuda for desktop HDDs, and SkyHawk for surveillance applications. The IronWolf Pro we are reviewing today weighs in at 705g each, or about 1.55lbs. This is exactly the same as the BarraCuda Pro ST12000DM0007 12TB according to the latest specifications sheet, both of which are equipped with relatively thin platters. On the label, you will spot information like its 12TB drive capacity, model name, serial number, model number, part number, firmware revision, manufacturing date, bunch of regulatory logos, and that it is a product of Thailand. The Seagate IronWolf Pro series come with a five-year limited warranty.
Turning the Seagate IronWolf Pro ST12000NE0007 12TB around, and you will see a green printed circuit board that interfaces between its SATA 6Gb/s interface and the physical mechanical components. Mechanically, the Seagate IronWolf Pro ST12000NE0007 12TB is a 7,200RPM drive with eight high density platters inside. The drive is helium filled for reduced resistance, which means more platters can be stacked in the same amount of space along with reduced power consumption. With these high-density platters using traditional perpendicular magnetic recording technology as opposed to performance-penalizing technologies like shingled magnetic recording, this should translate to great performance in our benchmarks. You will see 10.9TB in Windows. The rated power consumption is 0.8W standby, 5.0W idle, and 7.8W active operating power, which is really good. It is rated the same as the 10TB model and consumes marginally more active power than the 8TB model, which is excellent.
As far as electronic components are concerned, the Seagate IronWolf Pro ST12000NE0007 12TB features an Avago DS01 drive controller. To control the motor, a SMOOTH/Seagate branded chip labeled 78060 V5 gets the job done. A massive Samsung K4B2G1646F-BCK0 DDR3-1600 256MB IC acts as part of the multi-segmented cache for the drive, as shown in our photo above.
Before we delve into the benchmarking, I would like to spend a little bit of time discussing the unique characteristics of the Seagate IronWolf Pro ST12000NE0007 12TB NAS drive. What makes a NAS drive, a NAS drive? From a hardware perspective, usually, it will feature optimized consumption. Since file servers are designed to be turned on 24/7, reduced power consumption can make a significant difference on your power bill, especially if you have many drives. Reliability enhancements are also made with what Seagate calls AgileArray. AgileArray dual-plane balancing refers to the disk being physically balanced properly to reduce excessive vibration and noise in a multi-drive configuration, such as your network attached storage system. The IronWolf Pro 12TB also comes with rotational vibration sensors to mitigate vibrations from other hard drives in a network attached storage environment. Thanks to its improved vibration tolerance, the ST12000NE0007 will play nice even if you have up to sixteen drives running concurrently in the same system. Its mean time before failure (MTBF) is rated at 1,200,000 hours, with a 300TB per year workload rate limit. Compared to the vanilla IronWolf, the non-Pro version only supports up to eight concurrent drives, MTBF rated at 1,000,000 hours, and 180TB per year workload rate limit.
As with all NAS drives, the Seagate IronWolf is ERC enabled. If a drive is not ERC enabled, it may be dropped out of a RAID array unexpectedly down the road. ERC stands for 'Error Recovery Control', which is Seagate's name for a feature that limits a hard drive's error recovery time to seven seconds (Western Digital calls it TLER; HGST calls it CCTL). According to Seagate, desktop hard drives may enter deep recovery mode, and could take twenty seconds or longer to deal with a bad sector. During this time, the hard drive will not respond. Because of this, RAID controllers may mark the drive as unreliable, because it has failed to respond within a set period of time.
For small NAS environments, most people probably will not need hardcore enterprise grade drives, which are usually quite expensive. TLER and related RAID array configuration problems are more crucial with demanding business environments than a home or SOHO NAS setup with just two or three drives. Linux software RAID that your network attached storage system implements is much more lenient with consumer desktop drives. Personally, I have run RAID 5 arrays in my QNAP systems from 2010 to 2014 using regular disks with absolutely no problems at all. However, drives like the Seagate IronWolf Pro ST12000NE0007 are specifically tested for compatibility, designed for reliability in this operating environment, and comes ERC enabled from the factory to ensure you will not experience related issues down the road. With a price comparable to desktop drives, the Seagate IronWolf series is simply a no-brainer if you are looking to fill up your file server.
