WD Red Pro 22TB NAS 3.5" Internal Hard Drive - 7200 RPM Class, SATA 6 Gb/s, CMR, 512MB Cache, 5 Year Warranty

Product Information

So, you can imagine how excited we were to slide them into one of our Supermicro servers, put them through our gauntlet of tests, and see what they are capable of outputting. The Ultrastar DC HC570 22TB data center HDD with OptiNAND™ technology is the next leap in data density. IronWolf Pro 22TB, which features a spindle speed of 7,200 RPM, wields a 512MB cache and delivers maximum sustained transfer rates of up to 285 MB/s.

It’s the pinnacle of the product stack with the very highest capacities, the highest sustained transfer rates, and all of the top features — like the new ArmorCache — for performance and reliability. Some WD HDDs do stand out internally, including the 22TB Gold, as they have an onboard iNAND and a controller for the flash due to WD’s OptiNAND technology, which we covered previously with the WD Red Pro. It’s made for multi-drive, high-performance environments where uptime and data integrity are of paramount importance. From my understanding under power loss situations it allows them to use disk rotational energy to create electricity allowing the disk to flush volatile memory cache and prevent data loss by using said electricity to allow for a 'proper' shutdown. Neilbob said:I'm not too sure why the performance had to be mentioned as a con, or at all for that matter.This is also true of the Red Pro, available at 22TB for even less than the surveillance-oriented Purple Pro. Its OptiNAND and ArmorCache technologies have unique performance and reliability benefits, but it is not ideal for raw storage. WD has two downloads on its site for HDDs: the Western Digital Dashboard and Acronis True Image for Western Digital. WD clearly believes that SSDs are the best solution for gamers, and for pure gaming that's absolutely correct, but gamers don’t just game.

The humble hard drive might not be selling as well as it used to, but a lot of that is surely due to the ongoing shift towards flash solutions at lower capacities.

WD Gold™ drives are available in capacities up to 24TB utilizing the OptiNAND™ technology's capacity-enabling feature. Since May 2022, Western Digital has the largest hard disk drive on the market, the 26TB Ultrastar DC HC670, one which is only available for data center clients because it is host-managed drive that is not drop-in replacements for CMR HDDs (more on that in our interview with WD’s Ravi Pendekanti, SVP of HDD Product Management).

Besides the new 22TB model, the WD Gold line is available in capacities as low as 1TB, making them ideal for a wide range of demanding storage environments.
