Seagate's HAMR to drop in 2020: Multi-actuator disk drives on the way

In 2020 Seagate will introduce its first multi-actuator disk drives using Heat-Assisted Magnetic Recording (HAMR) tech with 20TB capacities. This was revealed at the Open Compute Project summit, which took place yesterday and today at the San Jose Convention Center. Wells Fargo analyst Aaron Rakers was there and distributed …

Seagate's at it HAMR and tongs for growth as revenues shrivel again

Seagate's first quarter 2018 revenues sank 7 per cent year-on-year to $2.6bn, but the drive biz expects growth and is convinced its heat-assisted magnetic recording (HAMR) tech will help that. GAAP net income was $181m, up 8.4 per cent on last year's $167m. New CEO Dave Mosley's statement spoke of "solid execution and market …

Yeah, keep buying those SSDs, grins Seagate: Your data will be on our disks eventually, muaha

Seagate made a canine evening meal of its third 2017 fiscal quarter – with flattish revenues on the annual compare greeted by a disappointed Wall Street expecting more and marking the shares down 15 per cent. The full year revenue is likely to show an annual decline as well. Chairman and CEO Steve Luczo’s company recorded $2. …

Seagate plans to bring down the 16TB HAMR... soon(er)

Analysis Stifel MD Aaron Rakers went on a Seagate booth tour at SC16 and notes Seagate thinks it is a year ahead of WD and Toshiba with HAMR (Heat-assisted magnetic recording) technology. It is targeting 2018 for HAMR drive deliveries, with a 16TB 3.5-inch drive planned, featuring 8 platters and 16 heads. We assume it will be helium- …

Seagate ready for the HAMR blow: First drives out in 2017

Seagate is reducing its manufacturing capacity while still focusing on high-capacity disk drives for cloud and hyper-scale storage of unstructured data. This means it needs higher capacity drives, requiring new read-write head technology. It is a high-technology, nano-scale, clean room manufacturing process, and drive read- …

Seagate promises to HAMR us all with spinning rust next year

Comment Seagate has revealed fresh data on how it will increase areal density as well as a disk's IO rate from next year onwards. Analyst haus Stifel Nicolaus' MD, Aaron Rakers, attended an analysts' day at which Seagate said it is learning about potential caching techniques to ameliorate the write performance disadvantage of shingled …

Muted HAMR blow from Seagate: damp squib drive coming in 2016

Analysis Seagate R&D bigwig Jan-Ulrich Thiele says the first Seagate prototype drives built with heat-assisted magnetic recording (HAMR) will arrive in late 2016 and have just 4TB capacity, according to Heise.de. This is not quite right as what Seagate says is: "Seagate anticipates shipping a small number of HAMR qualification units to …

Seagate: We'll bring down the HAMR in 2017. But will we give you shingles?

Seagate has been talking about coming disk tech and expects to have a HAMR product in 2017. We have better visibility into Seagate’s view of the ending of the current perpendicular magnetic recording (PMR) era. The ending is delayed by narrowing the tracks so as to cram more of them on a platter. This is called two-dimensional …

6TB - big? Pah! Seagate plans to put out 8TB and 10TB MONSTERS

We got all excited about Seagate's latest 6TB drive but, really, we haven't seen anything yet. It has been revealed that the spinning rust company is anticipating 8TB and 10TB drives later this year. This info came out in the company's third quarter results earnings call, where chairman, president and CEO Steve Luczo was …

Million-dollar new disk tech could be USELESS for array vendors

Blocks and Files We've seen a lot of innovation in disk drive technology over the past year or so, tech into which millions of dollars of R&D as well as large amounts of time and effort have been poured. But from where we're standing at the beginning of 2014, it may ultimately be totally useless for storage array vendors. I'm thinking of …

You can't touch this: It's HAMR time for WD

In September 2012, Seagate boss Steve Luczo gave a presentation using a HAMR technology disk drive. Now, more than a year later, a WD exec has done the same with the company's own HAMR tech drive. There's got to be a joke here: WD exec nailed it with HAMR? If all you have is a HAMR every disk is a nail? (Give it up - Ed) HAMR …

Seagate to storage bods: You CAN touch this (at last). Stop, HAMR time

Seagate plans to demonstrate a coming HAMR disk drive in Tokyo next month. HAMR stands for heat-assisted magnetic recording and is a way of increasing a disk drive's capacity beyond the limits of current perpendicular magnetic recording (PMR) technology. At high areal densities PMFR technology breaks down because each bit …

Seagate's shingle bathers stalked by HGST's helium HAMR-head sharks

A performance-versus-capacity war is brewing in the hard drive industry with Seagate leading on disk-flash hybrids and WD-HGST on helium-filled devices. At a briefing session for tech journos yesterday, Seagate dropped hints of new solid-state hybrid drives (SSHDs) - which combine a non-volatile NAND cache with spinning …

WD HAMRs down shingles on disk drive road map

Analysis Twenty years ago a myriad of hard drive vendors pushing essentially the same technology fought themselves into oblivion. Over the coming years the remaining players will be pushing traditional technology to its limits to extend the life of hard disk technology. While the industry is pretty much standardised on perpendicular …

Seagate: We'll bring down HAMR in 2014 ... this year, you get shingles

Seagate aims to ship enhanced capacity shingled magnetic recording (SMR) disk drives later this year and bring in Heat-Assisted Magnetic Recording (HAMR) technology next year, a full two years earlier than supposed. Possibly this is its riposte to the helium gas attack mounted by WD subsidiary HGST. Shingled magnetic recording …

Seagate strikes trillion bit HAMR blow

Seagate has demonstrated heat-assisted magnetic recording technology with 1 trillion bits per square inch, a 30 per cent improvement in Toshiba's production record of 744Gbit/in2 with its MQ01ABD drive – a 2.5-inch, 5400rpm, SATA II drive. Seagate's highest production areal density is thought to be the 3TB Barracuda, a 3- …

MIT boffin: Salted disks hold SIX TIMES more data

A Singapore researcher claims that disk drives could hold six times more data by adding table salt to a bit-patterned media (BPM) process. This sounds bonkers but there is a pukka press release issued by Singapore’s Agency for Science, Technology and Research (A*STAR) which describes Dr Joel Yang's work. Bit-patterning is a …

TDK fires up LASERS to double hard drive capacity

Japanese disk drive head supplier TDK says it has added a laser heater to its platter licking devices to enable heat-assisted magnetic recording. In non-boffinry speak, this will double disk drives' areal density - and therefore double capacity. All suppliers have to do is come up with the right chemical mix for the platters. …
