Seagate Cool Wolf IronWolf Pro series hard drives are quietly revised, improving durability and other indicators.

Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com February 20 news, Seagate recently quietly updated the IronWolf Pro series of hard drives, although did not promote a large capacity of new products, but the new version specifications show that it has been upgraded in terms of durability, it can be said that the increase does not increase the price.

The full model naming rules of the original IronWolf Pro series products adopt the format of ST20000 NE 000000 (20TB). After representing the brand and capacity, NE has been changed to NT (such as ST20000 NT 001).

In terms of parameters, the new version is mainly different in terms of life, for example, the average failure time (MTBF) has increased from 1.2 million hours to 2.5 million hours, while the work load rate limit (WRL) has also been raised to 550TB / year (the old version is 300TB / year).

In fact, not only that, except for the maximum continuous transmission rate indicated by 20TB to maintain at 285MB/s, the other capacity versions have increased the range of 6~30MB/s varying, and the anti-seismic capability of the 18TB version has also changed, but this part of the specification is not easy to quantify and compare, and CTOnews.com can not say how to improve it.

Finally, Seagate changed the recommended number of storage devices such as the RAID from "no more than 24bay" to "unlimited". However, Seagate has not changed its product lineup and has maintained an optional 2~20TB capacity, with a five-year limited warranty and a three-year data recovery service, and the pricing remains the same.
