Western Digital is planning to use Microwave Assisted Magnetic Recording (MAMR) instead of Heat Assisted Magnetic Recording (HAMR) to produce hard drives with capacities of up to 40 terabytes by 2025:

WD has selected MAMR (Microwave Assisted Magnetic Recording) as its new HDD recording technology, which the company claims can enable up to 40TB HDDs by 2025. WD's rapid transition to MAMR is somewhat surprising, but the technology has been in development for nearly a decade. It certainly stands in contrast to Seagate's plans for using the laser-assisted HAMR (Heat Assisted Magnetic Recording) as the route to higher storage density.

The transition to the new recording process isn't immediate, but WD plans to have initial products shipping by 2019, and it had working demo models this week at its event in San Jose. The improved recording technology is needed to keep HDDs cost-competitive with the surging SSDs, but economics dictate that SSDs will never replace HDDs entirely, especially as the volume of data continues to grow exponentially; WD predicts that HDDs will account for ~90% of data center storage in 2020.

The technology announcement reportedly took the storage industry by surprise and MAMR doesn't have the same issues that have delayed HAMR:

WD pointed out that MAMR requires absolutely no external heating of the media that could lead to reliability issues. The temperature profiles of MAMR HDDs (both platters and drive temperature itself) are expected to be similar to those of the current generation HDDs. It was indicated that the MAMR drives would meet all current data center reliability requirements.

Based on the description of the operation of MAMR, it is a no-brainer that HAMR has no future in its current form. Almost all hard drive industry players have a lot more patents on HAMR compared to MAMR. It remains to be seen if the intellectual property created on the HAMR side is put to use elsewhere.

Will we have 100 TB by 2032?

AnandTech Interview With Seagate's CTO: New HDD Technologies Coming 17 comments

AnandTech interviewed Mark Re, SVP and Chief Technology Officer of Seagate, to talk about plans for upcoming hard disk drive (HDD) technologies.

Although shingled magnetic recording (SMR) lowers write speeds, a number of techniques help reduce the impact, such as banding together SMR tracks into certain zones with perpendicular magnetic recording (PMR) zones covering the rest of the drive rather than shingling, or adding more SLC NAND and DRAM cache. Seagate will be expanding its use of SMR to increase density in client drives, not just "cold storage" drives, but will be using partial SMR/partial PMR and caching in order to mitigate write performance issues.

For the moment, Seagate won't be using helium outside of products for capacity-demanding datacenter customers (such as the Seagate Enterprise Capacity 10 TB HDD). The company can reduce fluid flow forces inside air-filled HDDs using purely mechanical solutions. On the other hand, Western Digital has introduced helium-filled drives aimed at consumers and has a marketing name for its technology (HelioSeal).

Seagate HAMR Hard Drives Coming in a Year and a Half 9 comments

When will the HAMR drop? Supposedly in late 2018:

Seagate last week made two rather important announcements regarding its current and upcoming hard drives. First, the company said that it had shipped 35 million HDDs based on shingled magnetic recording (SMR) technology. Second, the manufacturer confirmed plans to launch commercial hard drives based on its heat-assisted magnetic recording (HAMR) technology by the end of 2018, the first time the company set a precise launch timeframe for such HDDs.

[...] This is not the first time that Seagate has made a HAMR-related announcement, but this is the first time when the company has set a particular launch timeframe for such drives. Previously, Seagate has implied that the first HAMR-based HDDs would feature a capacity of 16 TB, which is a significant increase from 12 TB hard drives due to be released in the coming weeks. Given the fact that data centers cry out for high-capacity drives, it is inevitable that HAMR-based HDDs with increased performance and higher capacities will be in high demand. Keeping in mind that late 2018 (by "late" companies usually mean the fourth quarter) is over a year away, Seagate is not sharing details about experimental deployments of HAMR-based HDDs that may be planned for 2017/early 2018.

An upcoming Western Digital 14 TB 3.5" HDD will store 1.75 TB per platter.

Glass Substrate Could Enable Hard Drives With 12 Platters 67 comments

Using a glass substrate instead of aluminum could allow 12 platters to be crammed into a 3.5" hard disk drive enclosure:

Even if many modern systems eschew classic hard drive storage designs in favor of solid state alternatives, there are still a number of companies working on improving the technology. One of those is Hoya, which is currently prototyping glass substrates for hard drive platters of the future which could enable the production of drives with as much as 20TB of storage space.

Hard drive platters are traditionally produced using aluminum substrates. While these substrates have enabled many modern advances in hard drive technology, glass substrates can be made with similar densities, but can be much thinner, leading to higher capacity storage drives. Hoya has already managed the creation of substrates as thin as 0.381mm, which is close to half the thickness of existing high-density drives.

In one cited example, an existing 12-terabyte drive from Western Digital was made up of eight platters. Hoya believes that by decreasing the thickness of the platters through its glass technology, it could fit as many as 12 inside a 3.5 inch hard drive casing. That would enable up to 18TB of storage space in a single drive (thanks Nikkei).

When that is blended with a technology known as "shingled magnetic recording," 20TB should be perfectly achievable.

Toshiba is reportedly planning to release a 14 TB helium-filled hard drive by the end of the year.

Toshiba Will Adopt Western Digital's Microwave-Assisted Magnetic Recording Approach for Hard Drives 6 comments

Toshiba plans to boost its hard drive capacities by using Microwave-Assisted Magnetic Recording rather than Heat-Assisted Magnetic Recording. The company could use the technology to produce an ~18 terabyte hard drive:

Toshiba, like Western Digital, is going to use Microwave-Assisted Magnetic Recording (MAMR) to escape the inability of current PMR tech to go beyond 15-16TB disk drive capacity. [...] Seagate has chosen to [increase capacities] using heat (Heat-Assisted Magnetic Recording or HAMR). Proponents of the MAMR approach say HAMR stresses the disk surface and read:write heads rendering the disk unreliable in the long-term. Seagate disputes this and has demonstrated long life HAMR read:write heads.

Western Digital has chosen MAMR for its future technology and now we know Toshiba is doing the same.

[...] MAMR uses 20 - 40GHZ frequencies and the [Spin Torque Oscillator (STO)] bombards a bit area with a circular AC microwave field, lowering its coercivity and enabling the bit value to be written (magnetic polarity changed as desired.)

It is reckoned that MAMR could lead to 4Tbit/in2 areal densities, beyond the 700 to 1,000Gbit/in2 used currently, and leading to 40TB drives.

Toshiba and Showa Denko Produce 18 TB MAMR Hard Drives 6 comments

18 TB HDDs: Toshiba Collaborates with Showa Denko for MAMR HDDs

Showa Denko K.K. (SDK) announced on Thursday that it had completed the development of its microwave assisted magnetic recording (MAMR) platters for next-gen hard drives. The company is set to ship platters to Toshiba, which plans to start sampling of its new 18 TB nearline HDDs later this year. In addition to MAMR media, Showa also plans to release disks based on the heat assisted magnetic recording (HAMR) technology in the future.

The new 3.5-inch platters from SDK feature a 2 TB capacity and a new magnetic recording layer whose coercivity can be lowered using microwaves (see our brief description of the MAMR technology). SDK is not specifying which magnetic alloy or substrate it's using for its 2 TB media, but according to Western Digital, both should be very similar to those used for today's platters based on the perpendicular magnetic recording (PMR) technology. Which for Toshiba and its consumers means predictable pricing and reliability.

SDK says that Toshiba is set to use nine 2 TB platters for its 18 TB MAMR-based nearline HDDs, which will begin sampling later this year (and which will probably be commercially available in 2020).

Seagate to Stay the Course With HAMR HDDs, Plans 20 TB by 2020, ~50 TB Before 2025 28 comments

Western Digital recently announced plans to use Microwave Assisted Magnetic Recording (MAMR) to build its next generation of hard disk drives instead of Heat Assisted Magnetic Recording (HAMR). WD promised that initial drives will ship in 2019, with 40 terabyte drives available by 2025.

In response, Seagate has reiterated its plans to produce HAMR hard disk drives in the near future. The company says that its first HAMR drives will ship around 2018-2019 (40,000 have already been built and are being tested by leading customers), at capacities of 16 TB or more. From there, Seagate expects to develop drives storing around 50 TB "early next decade", and eventually drives with capacities of up to 100 TB by combining HAMR with bit-patterned media and two-dimensional magnetic recording (PDF):

HDD technology has become somewhat boring. Innovation has slowed, but that's largely because we've reached the limits of PMR (Perpendicular Magnetic Recording), which is the key underlying HDD recording technology. Over the last two years, we've seen a few interesting new technologies that let us cram more bits into the same old 3.5" HDD, such as SMR (Shingled Magnetic Recording). Unfortunately, the new tech comes with slower performance and often requires radical system changes if you want to unlock the full performance. That isn't worth the small capacity improvement unless you're deploying tens of thousands of HDDs.

[...] WD's MAMR relies largely upon proven technologies, which is a plus, but Seagate claimed that it's already producing the more exotic HAMR drives on the same production lines as its existing PMR-based drives. It also said that it has already built a strong supply chain for the new materials.

Both WD and Seagate have solid arguments for their chosen technologies, but the market will determine the winner. Both technologies will undoubtedly provide similar characteristics to today's HDDs, such as endurance, reliability, performance, and power specifications, so cost will be the true differentiator. As always, cheap and good enough will win. The HDD industry settled on PMR recording in 2005, and all three big vendors continue to use the same underlying technology. The move to two different technologies should make for a more exciting HDD future. Seagate plans to provide an update on its progress in early 2018.

Toshiba Announces its Own Helium-Filled 12-14 TB Hard Drives, with "Conventional Magnetic Recording" 13 comments

Toshiba is sampling a 9-platter, 14 terabyte hard disk drive that uses "conventional magnetic recording", aka the traditional perpendicular magnetic recording (PMR) with no shingling:

The new series comes with both 14TB and 12TB disks that wield nine and eight platters, respectively. Toshiba also becomes the only company with a nine-platter drive with 18 heads. Each platter packs 1.56TB of data storage.

Competing HDD vendors (WD and Seagate) have used helium designs for several years, so Toshiba has largely been considered late to adopting a helium design. Toshiba fills the 3.5" drives with helium instead of air and uses a laser sealing process to contain the gas. The helium reduces internal air turbulence from the spinning disk. In turn, it reduces vibration and provides power, performance, and reliability advantages. It also allows the company to use thinner platters, which facilitates the additional ninth platter.

While Toshiba may be the last HDD vendor to market with a helium HDD, the company did it in style. The MG078ACA, which carries a tongue-twisting name because it is destined for the data center, currently weighs in as the densest HDD on the market using conventional recording techniques. That represents a 40% increase in density over Toshiba's previous-gen 10TB models.

[...] Toshiba currently has 24% of the HDD market share according to Coughlin and Associates, which comes in third to Seagate (36%) and Western Digital (40%). The company has been surprisingly resilient and has clawed back market share over the last year. The addition of a class-leading 14TB model should help it gain even more market share over the coming year.

Both drives have a 5 year warranty.

1.8 TB 9th-generation PMR platters are possible and could be used in a 16 TB Toshiba HDD late next year. Will we see 2 TB per platter without the use of HAMR/MAMR or shingles? Combine that with 12 platters (using a glass substrate), and suddenly you can have a 24 TB HDD.

Seagate Plans 36 TB HAMR HDDs by 2022, 48 TB by 2024 11 comments

Seagate HAMRs out a roadmap for future hard drive recording tech

Seagate has set a course to deliver a 48TB disk drive in 2023 using its HAMR (heat-assisted magnetic recording) technology, doubling areal density every 30 months, meaning 100TB could be possible by 2025/26.

[...] Seagate will introduce its first HAMR drives in 2020. The chart [here], from an A3 Tech Live event in London, shows Seagate started developing its HAMR tech in 2016 and that a 20TB+ drive will be rolled out in 2020.

The last PMR drive appears in 2019/20 with 16TB capacity. Seagate's current highest-capacity drive is a 14TB Exos 3.5-inch product.

There is a forecast of areal density doubling every 2.5 years, and Seagate shows two other HAMR drive capacity points: 36TB in 2021/22 and 48TB in 2023/24. Capacity goes on increasing beyond 2025, with 100TB looking likely.

The firm makes the point that HAMR drives will be drop-in replacements for current PMR drives. Seagate will actually develop performance-optimised HAMR drives with MACH.2 multi-actuator technology – two read/write heads per platter – and capacity-optimised drives with shingled magnetic recording (SMR). These are shown in a [second chart].

Seagate Announces a 14 TB Helium-Filled PMR Hard Drive 12 comments

Seagate has announced a 14 terabyte helium-filled hard drive that uses perpendicular magnetic recording (PMR) rather than shingled magnetic recording (SMR). Toshiba announced a similar drive in December:

Seagate this week formally introduced its first hard drive with 14 TB capacity aimed at cloud datacenters that does not use shingled magnetic recording. The new Exos X14 HDDs are filed with helium and are based on the latest-generation PMR (perpendicular magnetic recording) platters, running at 7200 RPM.

[...] The Exos X14 is Seagate's response to Toshiba's MG07ACA HDD with 14 TB capacity announced last year, although until we recieve further information, we cannot do a direct comparison. The major benefit of both drives is their increased capacity that enables datacenter operators to store 3360 TB of data per rack (compared to 2440 TB with 10 TB HDDs), which is a key advantage for companies that need to maximize their storage capacity per square meter and per watt, while meeting other TCO objectives. Another indisputable win of 14 TB hard disks from Seagate and Toshiba (vs. HGST's Ultrastar Hs14) is their conventional magnetic recording technology, which ensures predictable writing performance and permits drop in compatibility of the HDDs with existing storage applications.

The author guesses it will have nine ~1.55 TB platters, like Toshiba's version. 9th-generation and beyond PMR platters that can store 1.8 TB or more may be seen before the technology is phased out:

[November 2017's] top-of-the-range enterprise-class 3.5" HDDs from Seagate and Western Digital can store up to 12 TB of data. They are based on eight 8th generation PMR platters featuring ~1.5 TB capacities. Toshiba is a little bit behind its rivals with their 10 TB units featuring seven 8th gen platters with 1.43 TB capacity. With the arrival of the 9th gen PMR platters in 2018, hard drive makers will be able to increase the capacities of their eight-platter models to 14 TB, while designs with seven platters can go up to 12 TB.

Seagate HDD Roadmap: 50 TB by 2026, 100 TB by 2030, Then 120+ TB 15 comments

Seagate: 100TB HDDs Due in 2030, Multi-Actuator Drives to Become Common

Seagate is on track to deliver ~50TB hard disk drives by 2026, ~100TB HDDs by 2030, and 120TB+ units early next decade, according to the company's recently revealed product and technology roadmaps. To hit capacity targets, Seagate will have to adopt new magnetic recording technologies. To ensure the high performance of its future drives, the company plans to leverage its multi-actuator technology more broadly. This tech doubles the performance of its hard drives, and it could become a standard feature on some of the company's product lines.

[...] Today's [heat-assisted magnetic recording (HAMR)] media is expected to enable drives featuring 80TB ~ 100TB capacity, according to developers. But, for 3.5-inch HDDs with a ~105TB capacity and 5 ~ 7Tb/in2 areal density, new ordered-granular magnetic films will be needed as grains will get very small and tracks will get very narrow. But ordered-granular media is expected to be a relatively short stop before 'fully' bit patterned media (BPM) technology comes into play with an 8Tb/inch2 areal density.

[...] A straightforward way to increase the [input/output operations per second (IOPS)]-per-TB performance of an HDD is to use more than one actuator with read/write heads, and this is exactly what Seagate is set to do. Using two actuators instead of one can almost double throughput as well as IOPS-per-TB performance, which is tremendously important for data centers. Furthermore, doubling the number of actuators also halves the time Seagate needs to test a drive before shipping, as it is faster to inspect eight or nine platters using two independent actuators, which lowers costs.

Western Digital Shipping 14 TB Helium-Filled Shingled Magnetic Recording Hard Drives 18 comments

Western Digital is now shipping 14 TB hard drives. The products use shingled magnetic recording (SMR), which can slow down re-writes:

Western Digital has started to ship its new HGST Ultrastar Hs14 hard drives, promoted as being suitable for cloud datacenters and for hyperscale developments. The capacity increase from its predecessor, the Ultrastar Ha10, from 10TB to 14 TB offers a significant performance improvement. The new 14 TB HDD is based on shingled magnetic recording technology, which is a system that naturally focuses more on sequential write performance. These drives will only be available with host management, which means it will not be available to general consumers, but only to select customers of HGST.

The HGST Ultrastar Hs14 relies on Western Digital's fourth-generation HelioSeal enterprise platform which integrates eight platters and features various internal components specially designed for such hard drives. The new helium-filled HDD has a 7200 RPM spindle speed, a 512 MB cache. and numerous enhancements when it comes to reliability and durability of the drive. As with other HGST enterprise-class HDDs, the Ultrastar Hs14 is rated for 2.5 million hours MTBF and comes with a five-year warranty.

      Hard drives may be on the way out for client computing systems, but, they will continue to be the storage media of choice for datacenters. The Storage Networking Industry Association has the best resources for identifying trends in the hard drive industry. As recently as last year, heat-assisted magnetic recording (HAMR) was expected to be the technology update responsible for increasing hard drive capacities.

      One of the common misconceptions amongst readers focused on consumer technology relates to flash / SSDs rendering HDDs obsolete. While using SSDs over HDDs is definitely true in the client computing ecosystem, it is different for bulk storage. Bulk storage in the data center, as well as the consumer market, will continue to rely on mechanical hard drives for the foreseeable future.

      The main reason lies in the 'Cost per GB' metric.

      Home consumers are currently looking at drives to hold 10 TB+ of data, while datacenters are looking to optimize their 'Total Cost of Ownership' (TCO) by cramming as many petabytes as possible in a single rack. This is particularly prevalant for cold storage and archival purposes, but can also expand to content delivery networks. Western Digital had a couple of slides in their launch presentation yesterday that point towards hard drives continuing to enjoy this advantage, thanks to MAMR being cost-effective.

      Despite new HDD technology, advancements in solid state memory technology are running at a faster pace. As a result SSD technology and NAND Flash have ensured that performance enterprise HDDs will make up only a very minor part of the total storage capacity each year in the enterprise segment.
