Seagate Update Ironwolf Pro Hard Drive Series with a new More Durable Enterprise NT Model
If you have been on the fence for a while about choosing the right Hard drive for your NAS, humming and ahhing about whether to choose a Pro series drive or an enterprise-class drive, then Seagate just made things a little easier for you with the release of the new Seagate Ironwolf Pro NT series of drives. Available now, these are new versions of the 2,4,6,8,10,12,14,16,18 and 20TB Seagate Ironwolf Pro series, but now have had a few build elements tweaked to improve their durability and workloads to be much more comparable to data center class drives – whilst still maintaining the advantages and firmware focus of the Ironwolf Pro HDD series.
What Are the Specifications of the Newer Generation of Seagate Ironwolf Pro?
The difference between the previous/current generation of Seagate Ironwolf Pro HDDs and these newly release NT versions is largely based on their build and design being much close to that of the Seagate EXOS series, which results in a higher sequential performance, longer/higher durability rating and a larger scope of deployment.
Main Key Differences Between Seagate Ironwolf Pro and the New NT Version
- Standard Ironwolf Pro drives can be used in upto 24 Bay enclosures, whereas these new NT drives are data center scale in their deployment and results in limitless enclosure volume support
- Standard Itonwolf dries have a 300TB annual workload, Ironwolf Pro can take 300TB a year and the new Seagate Ironwolf Pro NT series can reach take 550TB of writing per year
- Across the range of capacities of Seagate Ironwolf Pro and the new Ironwolf Pro NT versions, the new NT version is around 15-30MB/s faster on reported sequential performance (likely higher in typical ad-hoc use)
- The Seagate Ironwolf NT series arrives with a reported 2.5 Miliion hours MTBF vs the 1 Million on standard Ironwolf Pro drives
Here is how the two versions of Seagate Ironwolf pro compare side by side on the rest of the specifications
