Call the doctor! WDC's new 14TB spinner has shingled write scheme

WDC has released an Ultrastar 14TB disk drive with host application software managing its shingled writing scheme. It is the world's first 14TB disk drive, and is helium-filled, as usual at these greater-than-10TB capacities. The disk uses shingled media recording (SMR) with partially overlapping write tracks to increase the …

Seagate's Kinetic drives: They're moving... but in what direction?

Comment It was just 18 months ago that we were all writing about the release of new object-based hard disk drives from Seagate: Kinetic. The idea was that the drives didn’t use traditional storage protocols like SAS and SATA, but instead stored objects written and retrieved over Ethernet. Effectively, each drive is a large key-value …

Spinning rust fans reckon we'll have 18TB disk drives in two years

We could see nine platter helium-filled disk drives because the manufacturers can cram more thinner platters inside a helium-filled enclosure. According to a TrendsFocus report, current disk platter separator components could be eliminated and enable eight or nine platters to be used in the same 3.5-inch enclosures that …

Official: Seagate notebook drive has shingles

Seagate has delivered on its September 2015 technology announcement with a thin drive for notebooks that uses shingled magnetic media to get to a 2TB capacity level. The 2.5-inch Mobile HDD is 7mm thick (thin?) and weighs 3.17 ounces (90g). It has two platters, a 12MB cache and a 6Gbit/s SATA interface. The peak IO rate is …

Radian inflicts shingles on poor, unsuspecting Flash drives

Radian Memory, startup pusher of faster SSD software, claims its SSD-managing software can work with host-managed shingled disk drive software to make an SSD-SMR disk combination quite exciting. We'll see. Shingled Magnetic Recording (SMR) disk drives gave higher capacity than normal drives by overapping wide write tracks, …

Shingled drives get SpectraLogic archive down to 9 cents/GB

Spectra Verde DPE is a Shingled Magnetic Recording (SMR)-based NAS disk platform for high-density bulk storage at costs as low as 9 cents/GB raw. Shingled drives have sets of overlapping write tracks with side-by-side narrower read tracks to increase density. The downside is that a whole set of write tracks have to be …

So what exactly sits behind Google’s Nearline storage service?

Comment How is Google’s retrieval service for non-essential data, Nearline, with its three-second retrieval latency, viable at the same cost as Amazon’s Glacier, when it uses tape with a 3-5 hour retrieval latency? Tape is cheap – but slow – and Google can't be using the stuff for Nearline. We think Nearline uses either Blu-ray …

HGST shimmy shimmy shingles its way to a 10TB spinning rust drive

HGST has cracked the 10TB barrier with a shingled helium drive for active disk archives. Think of it loosely as a shingled He8. Like the He8, the Ultrastar Archive Ha10 is a helium-filled drive in which platters spin with less friction and vibration than in an air-filled drive. The same physical drive enclosure can hold more …

Aggressive HGST hurls flashy humdingers at online archiving

Comment Holy Moly, HGST is getting ambitious. It's building an active archive platform product in competition with some of its OEMs and its aiming to rewrite server clustering with a flash fabric - oh and develop helium-filled disk drives - and shingled drives with its own slant - and thinking of Phase Change Memory chips with DIMM …

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 …

Never mind software-defined HYPE, 2014 will be the year of REALLY WEIRD storage boxen

Storagebod As as we come to the end of another year, it's worth looking forward to see what – if anything – is going to change in the storage world next year, because this year has pretty much been a bust as far as innovation and radical new products are concerned. So what is going to change? I get the feeling not a huge amount will. …

Now Seagate posts declining results. Can new tech lift it upwards?

Seagate announced disappointing quarterly results but its underlying trends are positive as it makes big bets on new technologies. In the quarter ended September 27 Seagate’s revenues were $3.5 billion ($3.7 billion a year ago) with profits of $427 million ($582 million a year ago). The annual compare is coming off the tail- …

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 …

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 …
