On December 3, Seagate officially launched two 20TB high-capacity HDDs, Exos X20 20TB and IronWolf Pro 20TB, both of which have already achieved mass production. This also fulfills the promise made by Seagate a few months ago that these hard drives will be used for large-scale data centers, small and medium-sized enterprises, and NAS applications.
It is reported that these two hard drives are based on the Conventional Magnetic Recording (CMR), with up to 10 discs packed inside the helium-filled technology, a single disc is 2TB, the rotation speed is 7200PRM, and the cache is 256MB.
Among them, the Seagate Exos X20 20TB large-scale enterprise and large-scale data center provide two interfaces of SATA 6Gbps and SAS 12Gbs, optional SED self-encryption. It also has an ultra-low latency of 4.16ms and an enhanced cache function, so the performance is very powerful. In terms of reliability, it supports Seagate Secure security technology and provides a 5-year limited warranty. The mean time between failures reaches 2.5 million hours, and the annual data write volume reaches 550TB.
The IronWolf Pro 20TB is mainly for small and medium-sized enterprises and NAS applications. It is equipped with a rotating vibration (RV) sensor, which provides vibration resistance, reduces delays, and enhances the performance of the NAS system. In terms of reliability, the mean time between failures is reduced to 1.2 million hours, and the annual data write is reduced to 300TB, and there is also a 5-year limited warranty.
As for the price information, the two new 20TB hard drives, the Exos X20 and the IronWolf Pro will be shipped within this month. The prices are $670 and $650.
It is worth mentioning that Seagate is also increasing the production of hard drives using Mach.2 technology. Previously, Seagate’s Chief Financial Officer Gianluca Romano said at the 2021 Global Virtual Technology Conference, Seagate is developing the second generation of HAMR technology, the capacity of the new hard drive may be increased to about 30TB.
