Seagate launches its 20TB IronWolf PRO HDD

Seagate has now announced two highly anticipated 20TB hard disk drives (HDDs), The Exos X20 20TB and the IronWolf Pro 20TB are both conventional magnetic recording (CMR)-based hard disk drives (HDDs) that will be available for purchase later this month for £669 and £559.90, 

While solid-state drives (SSDs) are far faster than traditional hard disk drives (HDDs) in the consumer market, they fall short in terms of raw capacity, which is a critical consideration for enterprise applications. The IronWolf Pro 20TB is designed specifically for high-volume network-attached storage (NAS) workloads, and it can achieve sustained transfer speeds of 285MB/s on a single channel. There are also integrated rotational vibration (RV) sensors and a three-year subscription to Seagate's Rescue Data Recovery Services included with the purchase of the drive.

For hyperscale data centers, the Exos X20 20TB, on the other hand, is the ideal storage solution. Seagate states that the drive was designed with cloud storage in mind and that it has three times the caching performance of comparable devices.Seagate claims that the Exos X20 hard drive may be used in conjunction with the company's recently announced Exos CORVAULT storage solution, which can house up to 106 Exos business drives in under seven inches (18 cm) of available rack space. Heat-assisted magnetic recording (HAMR) technology is already used by Seagate in their 20TB hard disk drives, which the company has made available only to a small number of customers so far. The more cheap models, on the other hand, are expected to find eager buyers in the price-sensitive SMB market.

Exos X20 provides advanced caching that performs up to three times better than systems that solely use read or write caching, thanks to its low latency of 4.16ms and consistent response times. Exos X20 also offers a higher sustained data rate (SDR) of up to 285 MB/s, which is significantly faster than previous models. Exos X20 20TB will be available for list price of $700 and IronWolf Pro 20TB is available for $650.
