Seagate Increases Ironwolf Pro NAS Hard Drive Capacity to 22TB and Partners with QNAP

Seagate has caught up with its rival, Western Digital, by launching its first hard drive with a storage capacity of 22TB (ST22000NT001). The IronWolf Pro is targeted towards NAS systems and uses conventional recording technology (CMR). Seagate has also announced a partnership with QNAP, a leading provider of network-attached storage (NAS) systems, to provide enterprise-grade NAS solutions.

The IronWolf Pro 22TB hard drive is a significant upgrade from the 20TB version, utilizing 10 platters that can hold 10 percent more data each. The hard drive uses helium as a filler, which reduces flow effects in the HDD housing, making it possible to use multiple magnetic disks in the same format.

According to the data sheet, the maximum throughput remains unchanged at 285 MB/s, which means that the SATA interface is more than adequately dimensioned. The DRAM cache holds 512 MB, and the power consumption increases slightly to an average of 6 watts when idle and 7.9 watts when active. The series is equipped with torsional vibration sensors for use in the NAS network with many other HDDs.

In systems with multiple drive bays, the so-called AgileArray technology with “two-plane balancing and time-limited error correction” ensures first-class RAID performance. The workload rating is 550 TB per year, and the MTBF is estimated at a high 2.5 million hours, with the maximum number of uncorrectable read errors at 1 per quadrillion bits read (1 per 10^15). The HDDs are designed for continuous use and come with a 5-year guarantee and a 3-year data recovery service.

Seagate’s partnership with QNAP aims to provide enterprise-grade NAS solutions to businesses of all sizes. With the increase in demand for data storage, QNAP has been leading the charge with its range of NAS solutions. The partnership with Seagate will allow QNAP to integrate Seagate’s hard drives into their NAS systems, providing customers with a reliable and cost-effective storage solution.

Seagate Ironwolf vs Ironwolf Pro

Seagate’s IronWolf and IronWolf Pro hard drives are both designed for use in Network Attached Storage (NAS) systems. The IronWolf series is aimed at home and small office users, while the IronWolf Pro series targets enterprise users who need high reliability and performance. The Pro series offers additional features such as a higher workload rating, longer MTBF (Mean Time Between Failures), and torsional vibration sensors for use in systems with multiple drive bays. The IronWolf Pro also comes with a longer warranty and data recovery services. However, the IronWolf series is more cost-effective and suitable for less demanding use cases. Overall, both series offer excellent performance and durability for NAS applications, and the choice between them depends on specific requirements and budget.
