Western Digital's 22TB hard drives are available to buy

pcgamer.com:

The humble hard drive might not be selling as well(opens in new tab) as it used to, but a lot of that is surely due to the ongoing shift towards flash solutions at lower capacities. At higher capacities, the HDD remains king. Western Digital has announced its latest 22TB hard drives, so if you need to store all 58 seasons of General Hospital (no judging!), you’ve got a bigger option.

Western Digital is shipping 22TB WD Gold, WD Red Pro, and WD Purple Pro HDDs. These aren’t consumer-oriented drives exactly, but they are retail drives. The WD Gold is designed for servers and workstations and they're built with reliability in mind. The WD Red Pro is a high-end NAS drive designed for 24x7 multi-user environments. Finally, the WD Purple Pro is designed for multi-stream video recording applications.

All three drives have a 3.5-in form factor, a SATA 6Gbps interface, 512MB of cache and spin at 7200RPM. They have a five year warranty and all are priced at $600 and can be bought directly from WD's online store(opens in new tab) if you're in the USA.

The three drives share the same 10-platter 3.5-inch helium-filled platform that uses energy-assisted perpendicular magnetic recording (ePMR) technology and triple-stage actuators (TSA). The 22TB Gold can reach a very impressive sequential transfer speed of 291MB/s, while the Red Pro and Purple drives hit a respectable 265MB/s.
