Seagate offers mass storage designed specifically for RAID operation in Network Attached Storage (NAS) systems under the brand names IronWolf and IronWolf Pro. This storage family has now grown.
In addition to the previous two hard disk series with capacities of up to 14 TB, there are now also fast, noiseless solid state drives (SSDs) with the name IronWolf 110 SSD.
The advantage of an SSD is also in a NAS unit in far higher transfer rates, the significantly faster random accesses, a lower power consumption and silence. The IronWolf 110 SSD is available in capacities ranging from 240GB to 3.84TB to meet the needs of a wide range of applications, such as additional intermediate storage in a hard drive NAS or maximum performance as an all flash array.
In creating the IronWolf 110 SSD, Seagate relies on 3D TLC flash in combination with a controller that improves flash memory organization for higher and more durable memory performance.
Faster, more economical and more durable with DuraWrite
With Seagate’s DuraWrite technology, the IronWolf 110 SSD offers lossless data compression that effectively saves storage space and increases memory speed, as well as better physical memory utilization through dynamic overprovisioning.
At the same time, power consumption is reduced. It also reduces the amount of write operations, extending the life of the SSD. In addition, the IronWolf 110 SSD reduces the overall power consumption of the NAS, with corresponding energy cost savings for cooling.
As a special feature, the IronWolf 110 SSD offers protection against data loss in the event of a power failure. This is achieved by high-capacity capacitors (polymer tantalum electrolytic capacitors) that provide the power needed to complete a write operation in an emergency.
IronWolf Health Management Monitors and Warns
In NAS systems that support this, overall system reliability improves thanks to the Seagate IronWolf 110 SSD’s IronWolf Health Management (IHM). Prevention, intervention and recovery are equally important for the proactive protection of data. IronWolf Health Management” provides these provisions in the NAS systems in which the IronWolf family of storage devices operate.
This protection system is supported by the Synology, QNAP, Asustor, Thecus and Terramaster NAS units, for example, and protects these systems from disruptions before they can cause damage.
Prevention includes monitoring the system environment, continuously monitoring temperature, shock, vibration, disconnected connections, signal integrity and more. Depending on the NAS operating system, workload diagrams are also available to display traffic related to the NAS on a daily basis.
By analyzing hundreds of parameters, data loss can be prevented in time. If necessary, backup measures are recommended. IHM uses adaptive algorithms for monitoring important parameters of the hard disks with regard to data transfer, performance, readability, writability and overall reliability in order to adapt the recommendations to the environment and use.
Last but not least, Seagate offers two years of Seagate Recovery Services with the IronWolf 110 SSD. In the event of a storage unit failure (such as a disaster), users can use Seagate’s own data recovery and recovery service. In most cases, data is recovered in special rescue laboratories.
The laboratories are protected around the clock with physical monitoring and virtual security measures, and the data is stored behind closed doors with biometric scanners. In addition, the data returned is encrypted, whether in the cloud or on a data carrier. Further information can be found at https://www.seagaterescue.com/rescue-plans.
AgileArray – Technology for optimized continuous operation
The AgileArray technology of the IronWolf hard drives, optimized for RAID systems, is also used in the IronWolf 110 SSD. It includes hardware, firmware and software specifically designed for use in the NAS to optimize the performance and regenerative capability of these systems in the event of a failure. For example, the firmware on IronWolf and IronWolf Pro hard drives is specifically designed for multi-unit RAID operation.
Among other things, this firmware with Error Recovery Control (ERC) prevents the hard disk from making excessively long attempts to rectify errors on its own, which would cause the RAID controller to exclude the drive from the RAID system.
IronWolf up to 14TB Hard Drives
With the new IronWolf 110 SSD, Seagate has expanded its family of IronWolf and IronWolf Pro hard drives, both of which are well known and proven and are specifically designed for use in networked storage devices that accommodate multiple drives. It allows you to flexibly assemble systems that combine IronWolf or IronWolf Pro hard drives with up to 14 terabytes of storage capacity with IronWolf 110 SSDs.
In addition, the flash memories have the same SATA interface as the hard disks. Depending on the requirements of such storage units, the flash drives can assume the function of a fast buffer, or you can opt for the pure high performance of an all flash array.
High performance for continuous operation
The IronWolf and IronWolf Pro hard drives operate with high reliability in continuous operation in NAS systems. In addition, they offer high and highest reliability values and are protected against vibrations by torsional vibration sensors, as they occur in enclosures with several hard disks. This means that up to 24 hard disks can be operated without interference in one housing. The sensors register torsional vibrations transmitted by other hard disks in the network so that they can be compensated.
The IronWolf Pro hard drives are designed for a higher workload rate of 300 TB/year and also offer increased reliability averaging 1.2 million hours between faults (MTBF). The manufacturer gives a five-year warranty on these products and also provides the Rescue Data Recovery Service for two years (for IronWolf hard drives at a moderate additional charge).
