Seagate demos HDD that can do 480 MB/s With MACH.2 Multi-Actuator technology

Seagate demos HDD that can do 480 MB/s With MACH.2 Multi-Actuator technology

This HDD makes use of what is called MACH.2 Multi-Actuator technology, basically two magnetic heads and a bit of technology that sounds familiar to raid. 

Multi-actuator technology involves dividing a disk drive's platter reading and writing head stack into upper and lower halves and operating them in parallel to increase the drive's overall IO speed mentions cdrlabs. Seagate demonstrated up to 480MB/s sustained throughput - the fastest ever from a single hard drive, and 60 percent faster than a 15K drive;

The technology doubles IOPS performance in a single hard drive by using two independent actuators that can transfer data to the host computer concurrently. Seagate's engineering team also demonstrated reliability of its HAMR (Heat-Assisted Magnetic Recording) technology hard drives. Seagate revealed that its HAMR read/write heads have achieved unprecedented results in long-term reliability tests that surpass customer requirements by a factor of 20.

HAMR is a way of shrinking a disk drive's magnetised bits beyond the limits of current PMR (Perpendicular Magnetic Recording) tech, in which progressively smaller bits become unstable with error-prone bit values. The industry's standard specification for nearline hard drive reliability anticipates that a drive will be able to transfer 550TB per year, or 2750TB total over a five-year period. On a hard drive with 18 read/write heads, each head is expected to transfer 152TB reliably over five years. Seagate's development team has now demonstrated a single HAMR read/write head transferring data for 6000 hours reliably, equaling 3.2 Petabytes of data transferred on a single head. That's more than 20 times the amount of data required by the spec.

Seagate's OCP partners have begun integration development with both HAMR and our MACH.2 Multi Actuator technologies. Both technologies will be implemented in the near future in Seagate Exos enterprise hard drives. Actually Seagate's first 20TB multi-actuator disk drives based Heat-Assisted Magnetic Recording tech will be launched in 2020, according to Seagate. Seagate will first introduce a 14TB drive with multiple actuators in 2019, using a PMR technology drive. This is expected to be a high-capacity drive with more performance than single actuator drives. It will be followed by a multi-actuator HAMR drive with 20+TB capacity in 2020, followed in turn by 30+TB drives in 2021/2022 and 40+TB around 2023. Single-actuator HAMR drives are set for release with a 20+TB model in 2020, a 30+TB drive in 2021/2022 and a 40+ TB one in 2022/2023.

Seagate believes it can maintain a 10x $/GB gap between HDDs and SSDs through the leverage of next-generation technologies such as HAMR to drive to 2Tbpsi areal density (supporting 20TB HDDs) and ultimately 10Tbpsi (100TB HDDs), supporting a forecasted nine-year areal density CAGR of +30 per cent.

Western Digital and Toshiba are also including multi-actuator technology in their roadmaps. WD has chosen to pursue the development of the MAMR (Microwave-Assisted Magnetic Recording) technology to boost capacity beyond PMR limits.

Most standard drives people buy are only light duty. You can see this in the specifications, they are rated at 2400 hours a year. Surveillance drives I think are brilliant for backup, they are designed to be used 24/7 with constant writes. They only run at 5900 rpm for efficiency and reliability. You can also go Enterprise drives but they cost more.

I’ve had good luck with WD and okay luck with Seagate. But this is really cool honestly. If the price is right it would be a great game drive.


It wouldn't be much different for games as games generally load assets in small files.

This technology will still suck in small read/write ops compared to SSD, not to mention access time is slow

I agree ssd's improuved loading times is due to how much faster they are on average seek time comparing to an hdd

for home PC, sure. but the price of several terabytes of storage in SSD would be unreasonable.

100% agreed.

One of these drives would be awesome for a game stream drive and movie drive in my server.
