Announcement of Exos X16 - the first enterprise HDD at 16 TB

On June 4, 2019, Seagate Technology introduced, according to the company, the first enterprise-class hard drives on the market with a capacity of 16 TB. Devices of record capacity are included in the series IronWolf, IronWolf Pro and Exos.

In the sealed area of the Exos X16, filled with helium, there are 9 plates. Helium retains the temperature necessary for normal operation of the hard disk, preventing it from overheating. This makes devices more reliable to operate than traditional "air" HDDs.

Seagate released the world's first 16 TB enterprise hard drives

The new model is made in a 3.5-inch form factor and has a speed of 7,200 rpm. It is claimed that compared to 12-terabyte HDDs, the Seagate Exos X16 hard disk drive by 16 TB at the same size increases the capacity of one rack by 33% in petabyte terms, helping to reduce the total cost of ownership of storage environments.

Exos X16 is designed to use hyperscaled infrastructures, data centers, OEM systems and distributors.

IronWolf Pro and IronWolf drives are designed for multi-user NAS environments and are designed for workloads up to 300 TB/year.

IronWolf Pro is capable of transmitting data at a speed of 250 Mbps, and in IronWolf the maximum indicator is limited to 210 Mbps. The rotation speed is also 7,200 rpm.

All three new Seagate products received 256 MB of cache memory and are equipped with vibration sensors that, together with embedded software, compensate for external vibration interference.

Exos X16 has a price of $629, IronWolf 16TB and IronWolf Pro - $609 and $664, respectively. All drives are guaranteed for a period of three to five years. Sales of the 16-terabyte Exos X16 started in early June 2019.^[1]

Testing Seagate Exos HAMR Hard Drives

On December 4, 2018, Seagate announced the creation of a fully functional enterprise-class formatted drive, made in a standard 3.5-inch form factor, which has a capacity of 16 TB. Seagate plans to release more than 20 TB drives in 2020.

Test samples of 16-terabyte Exos hard drives based on HAMR technology were tested in the same mode that Seagate clients usually use when they install any drives into their information systems. Successful testing has confirmed that HAMR drives support plug-and-play technology and are no different in performance than other hard drives used in typical enterprise application environments. When they are installed in computing complexes of modern data centers, no architectural changes are required, since Exos disks connect in the same way as any other enterprise-class hard drives, Seagate emphasized.

During a modern digital era demand for stores of high capacity constantly grows, including due to formation of enormous data arrays on borders of networks and also as a result of rapid development of applications of artificial intelligence for which for training and obtaining new knowledge more and more large-scale data sets are required. Therefore, easy to install and operate high-performance high-capacity drives become indispensable attributes of the digital transformation of the world around us, Seagate believes.

Seagate has developed HAMR technology to significantly increase the amount of data placed on a single hard drive. As explained in Seagate, the HAMR-implemented carrier magnetization principle significantly reduces the area that is required to accommodate a data bit, significantly increases recording density, and provides a high level of magnetic stability. A miniature laser diode mounted on each recording head heats up the microscopic area of the disk surface, which allows the magnetic polarity of this area to be changed with a high degree of reliability and the data thus recorded. The HAMR drives developed by Seagate will be delivered in a standard form factor. This will reduce the total cost of ownership of information systems by placing a much larger number of terabytes of data in the same space required for smaller conventional hard drives.

"Seagate examines Exos HAMR disk prototypes using a standard set of benchmarks. Tests confirmed the comprehensive compatibility of HAMR drives with modern enterprise systems. We are fully convinced that there is no need for any system changes in the infrastructure, both during their operational testing and when deploying in client IT environments. During the standard integration test suite, Exos HAMR hard drives work just like any other drive. We used the same tests that our customers use to test new drives, to investigate their energy efficiency, determine the correctness of the execution of SCSI commands using the sg3 utilities, compare in the same environment HAMR hard disk drives based on perpendicular magnetic recording technology using smartmontools utilities, Evaluate the efficiency of data write and read operations in random, sequential, and mixed load modes. "

According to the developer's statement, the results of testing HAMR disks in a productive environment confirm the effectiveness of their use in enterprise information systems and complement the results obtained in the framework of laboratory tests of the reliability of HAMR drives. Based on HAMR technology, read-write heads have demonstrated higher reliability and health throughout the lifecycle than today's industry standards, exceeding the specifications of standard hard drives by 20 times.

Announcing the fastest hard drive

In March 2018, Seagate demonstrated, according to the company, the fastest hard drive in the world. It belongs to the Seagate Exos family of enterprise drives.

The device is based on the MACH.2 Multi-Actuator multi-actuator drive technology, which assumes that the reading and recording heads are located in different segments above the plate and work in parallel. This design doubles the number of I/O operations per unit time.

Seagate showcases the world's fastest hard drive

With MACH.2 Multi-Actuator, Seagate has achieved a record rate of 480 MB/s sequential read/write. By March 2018, HDD with a spindle speed of 7200 rpm has a throughput of 235 MB/s, and drives "developing" 15,000  rpm  have 60% lower performance than the new Seagate.

The presented Seagate Exos hard drive is intended for use in data centers, but the manufacturer does not exclude the release of the consumer version.

In addition to high speed, the new HDD claims a high level of reliability achieved thanks to the proprietary HAMR technology (Heat-Assisted Magnetic Recording), when the plates are locally heated to a temperature of more than 400 ° C, which allows increasing the recording density. At the expense of HAMR, the time between failures of one head was increased to 6000 hours, which is about 20 times more than the market needs. By February 2018, the company produced more than 40 thousand hard drives equipped with HAMR.

Seagate did not name the fastest hard drive, nor its cost. The start of sales of the product is scheduled for 2018. It is expected that at first 20 TB versions will be available on the market.^[2]
