Two series, two target groups: The new 28 and 30 TB hard drives from Seagate are designed for continuous operation - either in NAS systems or in professional storage infrastructures.
Those who store large amounts of data - such as video editing projects, photo collections, backups or virtual machines - reach their capacity limits with conventional hard drives. Seagate has introduced four new models that offer significantly more storage space at 28 and 30 terabytes. According to the manufacturer, the «IronWolf Pro» and «Exos M» series rely on proven technology and are designed to be particularly reliable, but are aimed at two different target groups.
Both series use the 3.5-inch format and offer a SATA interface with six gigabits per second. The height is 26 millimetres and the weight is around 695 grams.
«IronWolf Pro» series
The models in the «IronWolf Pro» series are designed for NAS systems in continuous operation. Both models - with 28 and 30 terabytes - are based on conventional magnetic recording (CMR) and are optimised for use in multi-bay systems. The drives are designed for an annual workload of up to 550 terabytes. The average operating time between failures is specified as 2.5 million hours.
The hard drives operate at 7200 revolutions per minute and achieve transfer rates of up to 275 megabytes per second. An integrated vibration sensor is designed to ensure stable performance even when several drives are operated in parallel. The power consumption is 8.3 watts in operation and 6.8 watts in idle mode. The «IronWolf Pro» is designed for 24/7 operation.
A special feature of the series is the «IronWolf Health Management». It enables status monitoring and provides information on prevention and error handling.
«Exos M» series
The «Exos M»series has a similar technical structure, but is designed more for use in scalable data centres, cloud systems and big data environments. CMR technology, helium filling and 512 megabytes of cache are also used here. The «Exos M» uses disks with a density of three terabytes per disk for the first time. This enables the high capacity with the same design.
The performance data largely corresponds to that of the «IronWolf Pro»: 7200 revolutions per minute, up to 275 megabytes per second transfer rate, 2.5 million hours average operating time. The power consumption is 9.5 watts in operation and 6.9 watts in idle mode. This hard drive is also designed for continuous operation, supports hot-plug functionality and offers comparable energy efficiency.
