Seagate launches 20TB SkyHawk NAS drive for surveillance



Seagate expanded its surveillance line of hard drives with the announcement of a new 20TB SkyHawk HDD. Designed for use with surveillance and other security systems, this latest addition to the SkyHawk family allows for even more data to be saved per drive in a NAS, DVR, or NVR environment.

Seagate already has 20TB hard drives, which makes this announcement that little bit less appealing to those who aren’t interested in a home or business security setup. Like Seagate’s Exos X20 and IronWolf Pro hard drives (some of the best NAS drives), the SkyHawk 20TB drive contains ten 2TB platters with helium gas.

The latest SkyHawk drive will spin at a maximum speed of 7,200 RPM and have the usual 6Gb/s SATA interface. With the latest 20TB model, the entire SkyHawk family consists of 8TB, 10TB, 12TB, 16TB, 18TB, and now 20TB. There’s 256MB of cache and a maximum data transfer rate of 260MB/s.

While the 20TB SkyHawk falls a little short compared to IronWolf Pro and Exos counterparts, this surveillance drive does have support for multi-bay network-video recorders (NVR) as well as AI-enabled NVR with up to 64 high-definition video streams. More interestingly the drives have a workload per year of 550TB.

To provide peace of mind, Seagate offers a limited five-year warranty, which is standard for such an HDD. The 2 million hours mean time between failures (MTBF) rating is also pretty good. I’ve yet to see 20TB surveillance drives from Western Digital, so Seagate has a small lead for the time being.

Seagate will sell the 20TB SkyHawk surveillance drive for £449.
