IronWolf vs IronWolf Pro

IronWolf vs IronWolf Pro


The biggest difference between the two is this:

  • IronWolf was designed for NAS drives in homes, SOHOs, and small businesses with up to 8 drive bays.
  • IronWolf Pro, on the other hand, is for businesses and digital artists who need extremely high performance from their NAS servers with up to 24 drive bays.

The larger Ironwolf drives, starting at 8 TB and higher, spin at 7200 rpm, while the smaller capacity models spin at 5400 or 5900 rpm, as can be seen in the comparison table above. But the 7200 rpm speed applies to all IronWolf Pro drives.


When selecting a NAS hard drive, capacity is an important factor. Thus, this part is about IronWolf vs IronWolf Pro for capacity.

Unlike Seagate Exos or FireCuda series, the IronWolf series is limited to 3.5-inch hard drive storage. IronWolf series drives offer a staggering number of storage options, starting at just 1TB (the Pro series starts at 2TB) and going up to 20TB per drive. IronWolf includes 1

TB, 2TB, 3 TB, 4TB, 6TB, 8TB, 10TB, 12TB, 14TB, 16TB, and 18TB, while IronWolf Pro includes 4TB, 6TB, 8TB, 10TB, 12TB, 14TB, 16TB, 18 TB, and 20TB.


Although both IronWolf and IronWolf Pro drive deliver excellent performance, the IronWolf Pro offers some benefits for high-end users looking for a high level of reliability.

At 4TB capacity, the Pro drive offers an additional 40MB/s transfer speed (up to 220MB/s for the Ironwolf Pro vs. 180MB/s for the Ironwolf) and double the cache. The Pro variant also boasts an average lifespan of 200,000 hours longer than the standard IronWolf. It provides faster access to your work files and, less backup time, a 20% longer average lifespan.

But in real life, which drive is faster will depend on your type of enclosure or rack. The IronWolf will likely lead in smaller compartments, while the Pro version will perform better in larger cases or storage racks. This can be attributed to the vibration optimization of the Pro version.

Reliability and Warranty

The Pro drives also have a higher workload rating of 300TB/year, compared to 180TB/year for the Ironwolf. Overall, Seagate seems to be less reliable at lower capacities. IronWolf provides a three-year limited warranty, while IronWolf Pro a five-year limited warranty.


The Ironwolf has a noise level rating of 23-32dB, which is low enough to place the NAS hard drive in your living room or in your study. Not all IronWolf Pro drives are as quiet because the professional audience that the Pro drives target does not really care much about sound levels. But they still stay under a pretty quiet 32 dB level.

How Much Space Should You Leave on SSD?

When a drive is filled to capacity, it can cause a variety of problems for Windows systems that are designed to function with a certain amount of empty space. The system may become slow or unresponsive, and it may be difficult to install new programs or save files. But just how much empty space do you really need?  Let’s say you have a 100GB hard drive. Windows will take up about 20-30GB, depending on which version you’re using, so you’ll have around 70GB left for your files.

And as a general rule of thumb, you should have at least 15% of your drive’s capacity free at all times. So in this case, you’d want at least 10GB of free space. Of course, if you have a lot of large files, you may need more space. And if you never delete anything, you may eventually run out of room. But as long as you keep an eye on your free space and make sure you have enough, you shouldn’t have any problems.
