Hard drives will use microwaves and lasers to store 60TB or more | Upscaled

  • With 16TB and 18TB drives, we're nearly hit the limits of how much data we can cram onto a hard drive platter. But a pair of new methods for writing data may enable a leap forward in capacity: heat-assisted and microwave-assisted magnetic recording, HAMR and MAMR (collectively called energy-assisted, or EAMR). Hard drives may feel old fashioned compared to flash SSDs, but these new methods use some cutting edge physics to cram as much as 60TB of data into a hard drive.
    All three of the big hard drive makers, Western Digital, Toshiba, and Seagate, are developing versions of this technology, and the first consumer drives just shipped.

      I don't think that is a smart idea.
      When one drive fails you want to rebuild the RAID. But there is chance higher than 50% that you get an non-correctable sector read error when reading more than about 12 TB. You would need 3 Disks.

  • @giornikitop5373
    @giornikitop5373 3 ปีที่แล้ว +3

    nice explanation. the main problem is, as capacities go up, transfer speeds must go up too because having to read let's say 10TB from a mechanical disk will take you several days to complete and the risk for fail is big. hdd speeds have not changed much. these new technologies are awesome, but if speeds are not within reason for the capacity, one of the biggest problems in storage, still remains even for archived data.

    Why is it that all the reporting on hard drives is about capacity? Seagate, for example, has developed a technology called Mach.2 with which they have increased IOPS and MB/s. This does not make their HDDs into SSDs, but at least more interesting if you want a compromise between capacity, price and speed.

      For the primary use, in datacenters, it isn't a problem. They still use HDDs because is still cheaper per GB than SSD, and they can balance traffic so no disk needs to run faster.
      In fact, this could be a nice option for having some sort of tape storage (now there are options up to 185TB!) replacement for information that doesn't require really long term storage or needs to be access fast.

The consumer demand for hdd is very low right now and enterprise is able to buy drives at a much higher cost, the enterprise derived consumer hdds are more expensive that way. These huge hdds are not very viable for daily consumer use. I would argue, that if you have the demand for a raid with 32gb drivey, you are most likely going to be able to suffer the cost, you are buying enterprise equipment none the less.

    All audio tape recorders use some form of bias when recording voice or music on tape. This is necessary for two reasons: one, to erase what is already recorded on tape; two, to ensure that even the most feeble sound is correctly recorded.
    This is normally achieved with a pre magnetization frequency (>100 KHz) applied with an "erase head" to the tape; and by applying the same frequency to the "record head", in addition to the audio signal to be recorded. The high frequency signal applied must be strong enough to override the magnetic reluctance (related to the coercivity you mention in the video) of the tape, and the various magnetic hysteresis. This high frequency signal must increase with the resistance to magnetization of the tape (the bias for a metal tape is 250% the signal necessary for a normal Fe-Cr tape).
    This is the first time I see a bias signal added to a digital recording. Using a radio frequency bias, in my view, is better than using heat. But this is the opinion of one, of course.

    While my day to day storage is on SSDs, I still use HDDs for backups and mass storage.
    A 15Tb HDD is still 10 times less expensive than an SSD of equal storage.
    And you should never store anything "in the cloud" that you would not want shared with everyone in the world - including your wife, daughter, mother and boss. Because "the cloud" really means, "someone else's server". And you are completely at the mercy of someone else's server security.

    The overriding concern of placing this much data on one device is recoverability. Unless I/O speeds are proportionally increased, the amount of time needed to extract/rebuild the data from a drive that was predicted to fail (via SMART) or had already failed (in some RAID config) could challenge the ability of the remaining like sized drives whose MTBF’s would be comparable at that moment. Even if only one drive prematurely failed and collective MTBF were not in play, how long would it take to reconstruct a RAID 5 or “10” array constructed from numerous 50TB drives? A long time even at highest SATA bus rates available today.

    This technologies are amazing, but one have to wonder if they even make sense. Right now we can create a 100TB ssd with easy. Clearly they are expensive, but most of the money go to the fact of they are unique. The Curie temperature is for Pierre Curie, one of his many contributions. I was a shame that he died so young, in his prime. Together with his brother (engineer) they were a magnificent couple of the experimental sciences.

    Something I don't understand, to heat a substrate above its curie point you need mm microwaves or infrared in the 100's nanometers wavelength but the tracks are less than a 50nm width. Can you explain how a laser shining an IR light in the 1000 nm would bring the current track at curie point without erasing all the neighbor tracks. The only wavelength able to target a 50-nm track would be in the gamma ray range but gamma ray do not heat a surface they just go thru it, and are pretty nasty to human without proper shields.

    I get the impression hard disk drive prices have remained overinflated. There was a time when prices would halve when higher capacities were released but even an 8TB drive is quite high in cost considering it’s quite old. Perhaps allowing companies to buy their competition out was not a smart move as there isn’t a need to be competitive anymore and they can easily keep prices inflated. I suspect these will have enterprise pricing for a long time as there seems to be a movement to take high capacity storage out of reach of consumers budgets forcing users to subscribe to cloud storage tightly linked to certain apps like Apple Photos + iCloud, Lightroom + Adobe CC storage etc

    Sounds like a bit of old magnetic technology from 100 years ago creeping in. Excellent. Back in the days of recording magnetic tape we needed an ultrasonic magnetic 'bias' signal that was applied with the audio signal being recorded. This got around the magnetic hysteresis problem for weak audio signals so the audio-frequency magnetic signal recorded on the tape was not butchered by the magnetic hysteresis in the magnetic medium. This is just like tapping the edge of the paper when demonstrating how a bit of powdered iron would align with the field of a permanent magnet underneath the paper. The tiny bit of mechanical energy from vibrating the paper helped the iron particles to finally settle into their correct places. That's how ultrasonic bias worked back in the day. What you described for the magnetically assisted methodology you were speaking of seems conceptually identical to old ultrasonic bias to me.

    I still don’t get why they can’t stripe data across the platters physically on top of each other so they can do simultaneous reads and writes off of every platter surface. So like an 8 platter HDD should be able to read/write 4 times faster than a 2 platter HDD. This seems like it’d make more sense than having two actuators.

    HAMR sounds like a philosophical descendant of the old super floppy drives.

    Are SSDs really more reliable? IMHO not. I have 4 HDs that I have had running for almost 20 years without turning them off. Of the 6 SSDs that I have had none of the originals still exist as all 6 have failed while still under warranty. Of the hundreds of HDs I have had in the past 30 years, I have had only one has failed while under warranty. I can usually predict when a HD is going to fail by the sound it makes. The only thing that SSDs have going for them is speed.

    Good luck with a HDD that needs 2 years to be written fully, assuming you write to it nonstop at the maximum speed.

    This feels like Sony's MiniDisc on steroids. MDs use a laser to heat up the magnetic material to its Curie point and use magnetic field to write data. The data on MDs is read with a laser head like a CD though.

    I seriously don't understand why sequential throughout doesn't increase with an increase in density. Are they only squeezing the tracks closer together and not making the "bit pitch" (along the track) smaller?
