In addition to MTBF and WRL, the new version even improves the maximum access speed.
Seagate recently quietly updated the IronWolf Pro series of hard drives, but it did not launch the long-awaited 22TB capacity version. In fact, everything remains the same, but the new version is shipped. The specifications show that the functionality is slightly different. It can be said that the increase in quantity does not increase the price.。
The IronWolf Pro series of hard disks that were launched and sold earlier, the complete model naming rules of the products are as follows: ST20000NO000 (20TB), after representing the brand and capacity NO This code, the new version is changed to NT（Such as ST20000NT001）。
Players have a few feelings, the first ismean time to failure (MTBF), increased from 1.2 million hours to 2.5 million hours (2 million hours for capacity of 10TB and below). Next, the Workload Rate Limit (WRL) will increase accordingly.The new version is relaxed to 550TB/year, while the old version is 300TB/year.
In fact, not only that, except that the maximum continuous transfer rate marked by 20TB is maintained at 285MB/s, and the rest of the capacity versions are increased by 6~30MB/s. Among them, the anti-seismic ability of the 18TB version has also changed, but this part is not easy to quantify and compare, so let’s ignore this small difference for the time being.
Finally, IronWolf Pro is applied to storage devices such as RAID. The old version suggested that the number of slots should not exceed 24bay, and the new version cancels it and changes it to unlimited.but Seagate has not changed the product mix at the same time, and still provides 2-20TB capacity options, including 5-year limited warranty and 3-year data rescue, and the market price strategy seems to be consistent.
The improvement of the above-mentioned zero-to-zero total specifications allows IronWolf Pro to be on par with its own enterprise-level model, the Exos series. Of course, there are still some differences in detailed functions and firmware adjustments. As for why Seagate will be updated in this way, it needs to be explained by the official, so we can’t make wild guesses.
