Seagate Unveils 14 TB Consumer HDDs: BarraCuda Pro, SkyHawk, IronWolf, & IronWolf Pro
by Anton Shilov on September 11, 2018 2:00 PM EST
Seagate on Monday introduced a portfolio of consumer-oriented 14 TB hard drives. The new HDDs belong to the BarraCuda Pro, SkyHawk, IronWolf Pro, and IronWolf series, and rely on the same helium-filled platform that powers the datacenter-oriented Exos 14 TB HDD introduced earlier this year.
As our review of the BarraCuda Pro 14 TB published earlier this week describes, all the new drives are based on Seagate’s helium-filled platform featuring eight 1.75-TB PMR platters with a 1077 Gb/in2 areal density coupled with two-dimensional magnetic recording (TDMR) heads. The HDDs also feature a 7200 RPM spindle speed as well as 256 MB of multi-segmented cache. Despite increase of areal density, the new desktop hard drives offer exactly the same sequential data transfer rate (250 MB/s) as their 12 TB predecessors. Meanwhile, like all helium-filled hard drives, the new 14 TB HDDs are very energy-efficient and consume just 6.9 W in operating mode, which is in line with previous-gen 12 TB drives.
While the new BarraCuda Pro, SkyHawk, IronWolf Pro, and IronWolf hard drives featuring 14 TB capacity use the same platters, heads and other components, they are still very different products aimed at different applications.
The BarraCuda Pro HDDs are designed for desktops, which is why they are rated for a 300 TB/year workload, but do not feature extensive protection against vibrations (unlike server-grade HDDs), yet they come with Seagate’s Rescue data recovery services.
By contrast, the Skyhawk drives are aimed at surveillance systems that usually employ multiple HDDs, which is why the HDDs feature advance protection again vibration. As such, these drives are optimized to work for 24/7 and can record data from up to 64 HD cameras. Seagate rates Skyhawk HDDs for 180 TB/year workloads.
Moving on to IronWolf 14 TB and IronWolf Pro 14 TB hard drives for NAS. Both models are outfitted with rotational vibration sensors and feature the IronWolf health management technology. Meanwhile the IronWolf Pro version aimed at enterprise NAS, also has top-and-bottom attached motor, and comes with a five-year warranty. Besides, the IronWolf Pro is also considerably faster than the IronWolf when it comes to maximum sustained transfer rate (250 MB/s vs 210 MB/s).
