About Ironwolf and Ironwolf Pros

Seagate Ironwolf and Ironwolf Pro HDD lineups are for NAS storage like WD RED and Red Pro series HDDs. The sub-series segmentation between the two brands is somewhat similar on paper. Ironwolf variants are made NAS in home/ SOHO and small businesses which typically consists of 1 to 8-bay NAS units. Naturally, they’re aiming towards the same customer base. Ironwolf Pro has higher feature sets as meant to operate in NAS with up to 24-bays, with 300TB/ year multi-user optimisation, higher Meantime Between Failures (MTBF), included data rescue service and therefore 5-year warranty.

Ironwolf NAS HDDs have 1 million MTBF and 180TB/ year multi-user optimization. It provides a three-year warranty and does not pre-include its data rescue plans.

About the Ironwolf 14TB…

This is the Ironwolf 14TB ST14000VN008 HDD drive, its highest capacity storage drive with 7,200 RPM. Apart from its elusive pricing, it would attract some type of users who will need 12.7 TB formatted mechanical drive in a single package.  All of this while maintaining its MTBF lifespan.

This Ironwolf and the Barracuda Pro 14TB use an aluminium chassis which are sealed tight to keep the helium inside. Helium helps to reduce resistance between the platters during operation and therefore better performance as its spindle’s rotational speeds are more effective against friction.

Storage Capacity

Many of such users are prosumers who store a lot of content for entertainment and professional reasons. The main on-paper specification shows the Seagate Ironwolf having 7200 RPM speeds, unlike WD Red which is in 5,400 RPM. While both companies can match capacity storage in mechanical drives, Seagate managed to get the upper hand.

Seagate’s ‘AgileArray’ is a combination of NAS specific features. This includes vibration tolerance, RV sensors, Multi-user optimization, RAID optimization and others. Seagate also has an embedded Health Management software which is used by some NAS to provide additional data about these HDD’s health status. It works in addition to S.M.A.R.T. functions and has six error code indicators:

The NAS which supports the newer codes gives information from the RV sensors and the SMART scan.

Internal Subcomponents

Seagate Iron 14TB Ironwolf uses the NANYA NT5CC128M16IP-D1 cache chip. Just like the Barracuda Pro 14TB, the thermal pads were practically glued in a sense that removing it will damage it beyond the point of reuse.

The system that I am using is to test most of the hardware. The same operating system, choice of SATA III port (SATA_1), version of the benchmark software and the testing method is maintained throughout the graph.

Operating System Windows 10 Pro 64-bit
Processor+ Cooler Intel i7 4790k + Noctua NH-U12S
Motherboard Gigabyte Z97X-Gaming GT
RAM 8 GB Kingston DDR3 HyperX
Primary Storage 240GB SanDisk Extreme II SSD
Source Storage 3 TB WD Red WD30EFRX
Power Supply ANTEC 1200W Quattro
PC Case Lian Li A70F

The testing methods are as follows:

AS SSD and ATTO Benchmark

Futuremark Storage Benchmarks: and PCMark 8 V2 Storage Test

AIDA64 Average Read/Write Access Tests: 64KB Block Size

Sequential Data Performance Test (4K Aligned and 512 KiB)

Random Data Performance Test (4 KiB and 256 KiB)

Transfer Test

AS SSD Benchmark

Test the sequential or random read/write performance without using the cache. AS SSD Benchmark reads/writes a 1 GByte file as well as randomly chosen 4K blocks. Additionally, it performs the tests using 1 or 64 threads and it determines the SSD’s access time.

Two extra benchmark tests examine the drive’s behaviour when (1) copying a few big files, a lot of small files and a mixture of file sizes by using cached copy functions of your OS as well as (2) reading/writing data depending on the data’s compressibility.

Data Throughput


ATTO Benchmark

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host bus adapters (HBAs), hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

PCMark 8 Storage Test

Use the PCMark 8 Storage benchmark to test the performance of SSDs, HDDs and hybrid drives with traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games. You can test the system drive or any other recognized storage device, including local external drives. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices.

More than just a capacity increase

Professional usage of storage drives is a major factor due to the 4K+ content and RAW images they have to store. This includes a series of raw footage, unedited and final end product archived in NAS. There are those who archive a lot of data, therefore large capacity storage in a single drive is vital. The 14TB is as big as it can get for now. Earlier it was 10TB and 12TB. These, however, make the transition towards capacity, performance and reliability Helium HDDs can only provide.

The main upside is the provision of 7,200 RPM class performance for non-pro series NAS HDDs, unlike with WD whose Red series provide 5,400 RPM class speeds. WD might catch up, but nothing yet so far.

About temperature and power…

The maximum operating temperature for the Ironwolf 14TB 008 HDD is the 70c. Higher tolerance to heat is one of the requirements of a NAS-specific drive. Helium added in an HDD casing with a total of 14TB worth spindles is the end result.

Typical use case

In a desktop use, the Ironwolf 14TB HDD operates between 35 degrees to 40 degrees Celsius, according to the HDD’s SMART data. A single bay NAS such as the successor models to the Synology DS112J has a slim form factor and relies on a 40mm fan to deliver airflow. Helium-filled HDDs are a boon here.

Storage Vs. Price

Unfortunately, it does translate to a higher cost. But there are lower capacity Ironwolf HDDs available with 7,200 RPM-class performance.

  • The highest storage capacity drive available at the time of writing this review
  • 7,200 RPM (Vs. 5,400 RPM WD Red) performance for ‘non-pro’ NAS HDD drives
  • Helium-filled drives perfect for NAS for silent and cool operation
  • Highest capacity storage drives traditionally discourages the mass from purchasing
