There was a time not terribly long ago when having even a terabyte of data in a single hard drive was unthinkable. Then, it happened, and data density has continued rocketing upward to this very day when Seagate released its first 22TB 3.5-inch hard drive. The new Seagate IronWolf Pro 22TB is available for purchase, and it’s not as spendy as you’d expect. The drive has been heavily discounted from the $599 MSRP to a mere $399.
Even a cheap solid-state drive (SSD) would be much faster than this spinning hard drive, but you can’t beat that capacity or the cost, which works out to about $18 per terabyte. The IronWolf Pro 22TB (model ST22000NT001) is filled with helium, which helps to protect the 10 platters and 20 read-write heads. It uses conventional magnetic recording (CMR) for improved reliability versus shingled magnetic recording (SMR). You might recall Western Digital got in hot water a few years ago for quietly swapping to SMR in its NAS hard drives.
At 7200 RPM with 512MB of cache, the new IronWolf has a maximum sustained transfer rate of 285 MB/s. The latest SSDs, on the other hand, can read data at more than 7,000 MB/s. Still, the IronWolf Pro 22TB is a little faster (7.5%) than Western Digital’s 22TB drive, launched late last year.
Seagate equipped the new 22TB drive with rotational vibration sensors to reduce noise. It idles at 20 dBA and jumps to 26 dBA during active seeking. That’s just a hair quieter than Western Digitial’s drive, which hits 32 dBA for active seek. The Seagate drive can get louder during heavy workloads, reaching as high as 34 dBA.

As an IronWolf product, this drive is engineered for extreme reliability in data center and network-attached storage (NAS) applications. Slap a few of these in a NAS enclosure, and you’ll have an almost unfathomable amount of redundant storage. However, nothing is stopping you from putting the IronWolf Pro 22TB in a desktop PC for local data storage. It has standard connectors for SATA III data and power.
You can find the killer above deal at Newegg, where the new 22TB drive is listed with a non-sale price of $479.99 and marked down an additional $80. Western Digital’s 22TB drive sells close to the $500 MSRP. It’s unclear if this is a Seagate-authorized promotion or if Newegg is just running an unexpected door-buster deal. It suggests NAS hardware on the page with the drive, and those machines are not cheap. If you need a ton of storage and 22TB just won’t do. Seagate has promised to launch 30TB drives later this year.
