Reviewing the IronWolf Pro 12TB ST12000NE0007 NAS Drive…

Earlier, we’ve talked about the IronWolf Pro series and test its IronWolf Pro 10TB drive. We’re reviewing the IronWolf Pro 12TB NAS HDD and see how this performs. It should be interesting to observe if this NAS HDD holds similar performance. To give a concise explanation, IronWolf Pro is made for commercial NAS operations. Naturally associated with the “Pro” word, it is recommended for NAS builds up to 16 bay drives, a higher mean time between failures, five years warranty period with rescue support for up to two years, vibration sensors and optimized HDDs for multi-user connections.

Since we already about its features and benefits of the IronWolf Pro earlier, we’ll simply go ahead with the testing.

SEAGATE IronWolf 110 ZA240NM10001 240GB NAS SSD Review

The Seagate Ironwolf 110 SSD is made for small to SOHO NAS arrays. While NAS bays do provide cages with both 3.5"/ 2.5" drives, there are some really small form factor NAS specifically made for 2.5" SATA drives for mechanical and solid-state. There are also 3.5"/2.5" hybrid NAS that uses SSDs as additional caching for the primary storage array. Naturally, this would make a market for NAS specific SSDs. This is the Seagate Ironwolf variant. The Ironwolf 110SSD comes with a set of its marketed features- AgileArray firmware and DuraWrite are two of these firmware specific implementations. These NAS SSDs do that have a 5-year warranty with an included 2-year data recovery support. Though the provision for this data recovery support varies between countries.
