Seagate’s IronWolf NAS hard drives have gained popularity for NAS systems due to its great reliability and transfer speeds, I’ve been using them in my Synology NAS for over two years and they have never failed me.

Seagate has sent us the IronWolf Pro 14TB drive for our review, it is currently the highest capacity in the market with a 7200RPM spin rate and 256MB of cache, this should be exciting for data heavy users as you will be able to expand more storage with reduced cost, imagine having up to a total of 168TB storage in a 12-bay NAS, that’s an extra 48TB of storage than having a 10TB drive per bay.

Otherwise, you will also receive other data protection features on this model too, such as a 2-year Rescue Recovery Data plan and IronWolf Health.

As Seagate puts it, IronWolf Health has adaptive algorithms that monitor critical drive and health parameters releated to data transfer, performance, readability, writability and overall reliability. (Note: At this time of reviewing, IronWolf Health is not yet made available on the IronWolf Pro 14TB, screenshot is taken from a Synology DS216+II with a Seagate IronWolf 4TB hard drive.)

In other features, the IronWolf Pro hard drive does have a better durability with up to 1.2 million hours of MTBF and is made to handle high traffic data transfers with up to 300TB/year of multi-user optimization, you also get 5 years of warranty as compared to the standard IronWolf drive, making this an attractive purchase should your business depends heavily on mission critical applications and data transfer activities.


Let’s dig into the drive’s actual performance, since Seagate only provided us one unit of the drive, we are running the drive’s data transfer tests on our test bench, as it will also show us the best possible performance of a single drive.

In terms of pricing, the IronWolf Pro 14TB will cost you around RM2798 when checked at Lazada, a RM610 premium over the IronWolf Pro 12TB, which is pretty reasonable considering that you are merely paying RM300 per TB of storage.
