About Ironwolf and Ironwolf Pros

Seagate Ironwolf and Ironwolf Pro HDD lineups are for NAS storage like WD RED and Red Pro series HDDs. The sub-series segmentation between the two brands is somewhat similar, atleast on paper. Ironwolf variants are made NAS for home/ SOHO and small businesses which typically consists of 1 to 8-bay NAS units. Naturally, they’re aiming towards the same customer base. Ironwolf Pro has higher feature sets as meant to operate in NAS with up to 24-bays, with 300TB/ year multi-user optimisation, higher Meantime Between Failures (MTBF), included data rescue service and therefore 5-year warranty.

Ironwolf NAS HDDs have 1 million MTBF and 180TB/ year multi-user optimization. It provides a three-year warranty and does not pre-include its data rescue plans.

About the Seagate Ironwolf 14TB…

This is the Ironwolf 14TB ST14000VN008 HDD drive, its highest capacity storage drive with 7,200 RPM. Apart from its elusive pricing, it would attract some type of users who will need a 12.7 TB formatted mechanical drive in a single package.  All of this while maintaining its MTBF lifespan.

This Ironwolf and the Barracuda Pro 14TB use an aluminium chassis that is sealed tight to keep the helium inside. Helium helps to reduce resistance between the platters during operation and therefore better performance as its spindle’s rotational speeds are more effective against friction.

Storage Capacity

Many of such users are prosumers who store a lot of content for entertainment and professional reasons. The main on-paper specification shows the Seagate Ironwolf having 7200 RPM speeds, unlike WD Red which is in 5,400 RPM. While both companies can match capacity storage in mechanical drives, Seagate managed to get the upper hand.

Seagate’sAgileArray’ is a combination of NAS specific features. This includes vibration tolerance, RV sensors, Multi-user optimization, RAID optimization and others. Seagate also has an embedded Health Management software that is used by some NAS to provide additional data about these HDD’s health status. It works in addition to S.M.A.R.T. functions and has six error code indicators:

The NAS which supports the newer codes gives information from the RV sensors and the SMART scan.

Internal Subcomponents

Seagate Iron 14TB Ironwolf uses the NANYA NT5CC128M16IP-D1 cache chip. Just like the Barracuda Pro 14TB, the thermal pads were practically glued in the sense that removing them will damage it beyond the point of reuse.

Cooler Master MasterBox NR200P SFF PC Case Review

The Cooler Master NR200P is a very interesting SSF PC case. It provides for motherboards in mini-ITX/ mini DTX layout, a layout which maintains the vertical length of the mini ITX while providing a longer width. Along with the SFX/ SFX-L spec power supplies, this case is to provide some interesting configuration options. miniITX cases come with some expected compromises. But with advancements in design from processors, chips all the way to layout and form factor specs, it reduces that compromise significantly.  In the end, we will see cases like these.
