Data Storage Media

300 gigabytes in the size of a DVD? 276

Posted by Hemos from the what-does-the-future-look-like dept.
Rollie Hawk writes "Although storage space is no longer the premium it once was, physical backups and external media have been slow to catch up. While recordable DVDs may be fine for backing up a single workstation, large servers are still forced to rely on swappable drives and tape backups. But holographic disc technology could be changing all of that in the very near future. Holographic Versatile Discs (HVDs) have been in the works for some time now by various companies, including InPhase Technologies (formerly part of Lucent) and Japan's Optware (which claimed to have made the first recording of a movie on a holographic disc last year). InPhase's HVDs, scheduled for release in 2006, are said to hold 300GB of data, 60 times that of a conventional DVD with only a slight increase in size. That translates to more than a day's worth of HD-quality video. Not to mention the drives themselves can read and write at ten times the speed a normal DVD drive. One of InPhase's partners in HVD research, Maxell, is working towards even more storage on a 1.6TB disc."

    Turner Network Television recently aired [tgdaily.com] a commercial off of the InPhase Tapestry drive. Maxell built that drive for InPhase.

    Data backup has become very expensive for some of my customers. The amount of data a company of even minimal size (50 employees) goes through in a day blows my mind. We've been investing every option but none are cost effective (except when a hard drive goes).

    My dilemma is that as backup storage (such as the HVD) gets bigger, it seems that hard drives quickly outpace the new form of backup storage. 1.6TB discs sound great, yet I'm weary of having that much data on an easy to break/burn/steal disc. 300GB is more feasible as I can see making a few copies of the backup "just in case."

    Nonetheless, the write speeds listed don't seem all that great, and what interfaces will let us copy data at those speeds? Moving 1.6TG of data off of a server without slowing down user access (24 hours per day with offshore employees) sounds like it will still take hours and hours to back up (if not longer). A recovery stage would take even longer.

    For now, I'm happiest with redundancy backups. I don't like mirroring or RAIDx/y or clusters (too many nightmares over the 15 years I've worked with all of it), but having a server dupe itself daily has given us the best turnover and safety margins we've seen, as well as being very cost effective compared to use-once media or (shudder) tapes.

      Let me introduce you to Mr. Tape Drive. This reel of magnetic tape is quite possibly the largest method of data backup used, and last I checked, it takes hours and hours (if not longer) to do full data backup of disks. This is why most companies implement RAID 1 or 5 solutions and use tape backup as a weekly or monthly system.

      Once again, the post-office will become the king of high latency high bandwidth. Hollywood should quake in their boots over this, not on-line file sharing.

        If these things are inexpensive enough ond can imagine peer-to-peer postal networks popping up. Say you record half of something on on DVD, and you send it to someone. They send you back half of something, and then you send the other half and so-on. tit for tat.

      The problem with the above concept is that it requires the sender and the receiver to actually haveing something each other actually wanted to exchange. But if the disks get big enough you could easily put many things on them increasing the probability that one or more things on their will be something someone else wants to share. It costs you no extra postage to send 1 thing as 100 things now.

      So this might blow that wide open. And sharing 100 to 1000 movies per 32 cent stamp, or sharing every single top 40 song for the last 100 years on a single Disk and it wont take long before everyone has every song and movie.

      Well, full disclosure first: this is what I do all day, every day. Backup and recovery, that is.

      So a few comments, because some of your thoughts worry me a bit:

      Backup is expensive. Backup is insurance. Ideally you never need to recover, which means that all that money spent on backup is "wasted". That is life. It is an operational cost of doing business, that many businesses pay because they recognize that the risk of not having one outweighs the expense of doing it. But there it is. And I do recognize that smaller businesses (less than 1000 employees) usually have a harder time understanding the costs and justifying them. So how do you define "cost effective" in backup? There is no conceivable way that it can be run as a profit center and make money. Backups cost the business money, just like their insurance policy. How much is your data worth? That is the core question. How much is it worth? How much will you lose if you don't have access to it for some period of time?

      Point number two is that the massively dominant mechanism for backup today is tape. I would venture to guess that 99.9% of business with more than 1000 employees backup to tape. And it is easy to break, burn, and steal. Again, that is life. We implement reasonable measures to ensure that it doesn't happen, but best practices say to make two copies of any tape: one for onsite, one for off. And yes, if you are concerned about data security (credit card transaction processors, banks, etc.) encrypt the tape. Yes it is expensive, and yet it is worth it. It is not "cost effective" except when you think that you may be out of business if your courier blows it, looses the tape, and the world finds out; just ask CardSystems Solutions. That is the context in which cost effective needs to be understood.

      Further, what interfaces let you copy data at those speeds? Well there are more options than I can outline in this post: multiple SAN interfaces? Multiple LAN segments? RAID array snapshots? Host based mirroring? etc. Lots of options, all with good and bad things about them. But again, RAID arrays are used by 99.9% of businesses with more than 1000 employees. Server duplication is *not* backup. It may suffice for disaster recovery, but it has two enormous problems: it does not preserve data as it used to be at a given point in time (say, at financial quarter end), and it does propogate errors. Corrupted tablespace? You just replicated corruption. User just deleted files? While they just got deleted remotely too. Redundancy accomplishes several things, but none of them are backup. No auditor would be satisfied with that, and if they company is traded publicly, the CIO would likely be fired if that strategy was revealed to the public.

The same way they have loaner equipment for many different types of new tech (cutting lasers, backup systems, network appliances) for large corporations. It's a perk for clients, a PR tease, and a way to get quotes from "CTO of BigCorp" to be used in their sales literature.

    It's not just that it's a fast drive. It goes well beyond the current method of spinning the disc faster and(or) putting the data closer together to increase performance.

    "Unlike other technologies, that record one data bit at a time, holography allows a million bits of data to be written and read in parallel with a single flash of light," says Liz Murphy, of InPhase Technologies. "This enables transfer rates significantly higher than current optical storage devices."

    That's pretty wild for a single "head" drive. I wonder if this could translate into devices similar to hard drives using similar methods. Hard disks are what I feel is holding back system performance. It's almost always the biggest bottleneck in a system, and has been more or less at a platoe for years, mainly because magnetic media can only do so much in a serial manor.

    • HDD will always be a bottleneck because they require actual physical movement. Even on the high end it is still thousands of times slower than you can move electrons through a bus. The only hardware solution to the problem is to compensate with allot of caching, or start using solid state storage. This is partly why Google stores data on huge banks of RAM.
      • And what's to stop us from switching to solid-state storage?

        You can already get flash drives as big as what, 8 gig? My laptop has only 40gig HDD, and that's plenty for me. I'd go down to 20 or 30 in a flash (ha ha) if it meant switching to steady-state.

    From the Wikipedia link:

    "The article notes that the transfer rate is at an average of 1 gigabit/second. That is equal to 0.125 gigabytes/second, or 128 megabytes/second, which is a large leap over earlier storage mediums, whose transfer rates are generally measured in Kilobytes/second. In comparison, a 56x CD-ROM drive transfers at up to 8.4 Megabytes/second, and 16x-speed DVDs transfer at 22 Megabytes/second."

    That is impressive indeed. But I have a question regarding the random errors etc due to statistical variation. How much resources do you have to devote for error correction (eg parity bit etc) ? And wouldn't it be very power consuming to do error correction at such a high data transfer rate ?

      Plenty of people already do error correction at line speed on gigabit communications links with low power costs. To someone developing coding schemes, storage devices can just be modeled as another communications channel.
    • You think actual drives do error correction at the rate you cite? Whenever an error occurs, the rate drops by a factor of ~100, the time to retry and blah blah. The transfer rate is only good if there is no error, like on any other device.
      • Yes, they do. You have to distinguish between the multiple layers of error correcting and detecting codes applied to the media. Modern designs often intentionally accept a relatively high BER at the physical level to gain increased density. These errors get corrected in a hardware decoder at line rates.
    • In comparison, a 56x CD-ROM drive transfers at up to 8.4 Megabytes/second, and 16x-speed DVDs transfer at 22 Megabytes/second.

      Hmm. I hadn't ever thought about DVD's reading that much faster than CD's. It's off topic, but for certain games that required data off the CD (and that don't use copy protection): couldn't you get a pretty good performance increase by taking the files from the CD and just burning them onto a DVD? Lots of wasted space but DVD-R's have gotten dirt cheap these days anyways.

    I could imagine that those things would be great for doing backups, but: Will they be reliable ?

    When writable DVDs and DVD burners got affordable I was thrilled at first: Finally being able to backup several GB of data to one not too expensive disk instead of on a stack of CD-Rs ! But then reality hit: Compatibility problems between individual brands of burners and brands of media, quality problems with media, even worse durability than CD-Rs; altogether more or less a total gamble if you want to do backups with that stuff. Now my DVD burners collect dust or are mostly used as CD burners only. So what is a high capacity medium good for if it is not reliable besides making expensive coasters and wall clocks ?

The results they got strongly depended on the combination of burner and media, and considering that even brand name media often is manufactured by changing OEMs makes selection of a working combination mere luck.

      That depends on your definition of high capacity, but if you're happy with the amount of data that would fit on a DVD-R, then your answer is DVD-RAM. It's significantly more durable, and it's the only format that drives can read and write at the same time. The +/- RW format disks die eventually, but I've not yet had a DVD-RAM die on me.

    In 1982, I had an Atari 400 (5MHz 8bit 6502) with a tape drive which cost $500. I upgraded its 16KB RAM to 48KB (replacement) for $500, and the tape to an 88KB (double sided) floppy for $500. Now I can get a P4/3.0GHz for $300, a $104 300GB HD, and 1GB RAM for $60. That's 1440x the CPU bandwidth, 16.4Mx the storage, 10.4Mx the memory for a dollar - which is itself worth less than half its value (in noncomputer goods) of a quarter-century ago. And the HD is 1/10th the size (volume), while the other components are about the same size. So it's clear that storage technology has advanced the most during the "PC revolution", by a factor of a thousandfold. The only competing tech is the transformation of my $500 300bps modem and $50:month Compuserve account to a $50 6Mbps DOCSIS modem at $50:month, which is 20-200Kx cheaper for WAN.

    I'm all for putting that 300GB into a cheap, tiny device. All the other cheap, even mobile networked computing has created mainstream demand for archive, beyond memory and storage. But I'm betting on it not because storage tech is somehow lagging. I'm betting on it because that industry is by far the highest performing personal computing innovation we've got.

      The 400 and 800 were tied to the NTSC clock, and were 1.8mhz.

      I still have all that stuff in storage, but the serial cables to plug it all together have gone bad over the years.

    I'm a little confused by some of the responses I'm seeing here. It seems most people think that this new technology would be a bad thing? The largest complaint I've seen so far is: "What if I lose the disk?" I don't know about you guys, but for me this isn't much different then anything else in the world. If your backup is important... don't lose it!

    If needed, I have some handy solutions to solve the "How do I not lose my disk" problem.

    1. Put it some place that you can remember.
    2. If it's super important, make two backups.
    3. Tie a string around your finger to remind you to always remember where you put your disk.
    4. Ask somebody more responsible than yourself to watch over it for you.

    And if none of these work...

    5. Buy a small cable. Run the cable through the hole in the center of the disk. Buy a small padlock. Padlock the cable around a large object. Make multiple copies of the padlock key and tape them in various places.

    Obviously this is not practical, but it is about as practical as thinking that a new technology is bad because you might misplace it.

    Even if it fits in current enclosures, it will never be a consumer-grade product like DVD-RW is now. Home DVD-RW for home theater just dropped below $100, and internal drives for desktops are under $30. Blu-Ray/HD-DVD could get there in 5 years (doubtful, as HD will remain a premium item for most of that time).

    Until there is a demand for prerecorded media with 300GB on it, there won't be the impetus to make these items cheap. They'll remain in the computer-room-only expensive category.

    What might make this technology fly is not a 300GB, 13cm platter, but a PSP UCD-sized disk for portable media with, day, 20GB on it. However, I suspect that falling flash memory prices will overtake this too quickly for it to have much impact on portable media players, camcorders, etc.

    It will be valuable and marketable to the server room customers, but don't expect Dell to include these babies in a $399 desktop for at least 6 years.

    In holographic media, read and write operations are usually done using different laser wavelengths. You use a "recording" wavelength to record an interference pattern in the media, and a "reading" wavelength which will diffract into the interference pattern and restore the original image.
    These wavelengths need to be different because holographic materials work like photographic films. If you try to read the hologram with a wavelength to which the holographic material is sensitive, you will destroy the interference pattern, and therefore the data.
    Wikipedia states that a 532nm laser is used for both reading and writing operations. That means they use a different way to store the hologram. Would anyone have more information about this ?
  • I'm sorry, but this sounds more than a little problematic. At ten times the write speed of a normal DVD, it sounds like buffer underruns would be the rule rather than the exception, unless you were able to use a medium-sized hard drive as a buffer. That means that you're looking not so much at the problem of disc errors from the drive's own hardware, but rather from disc errors because existing hardware can't keep up with it. It would be nice if write speeds could be decreased for compatibility, but this

    So instead of having to install a bank of hard drives just for single 120-minute movie in uncompressed digital format, you can reduce it all to a single HVD disc plus protective caddy weighing at most 5-6 ounces. This could drastically cut the cost of digital theater projection, since all you need is a small player connected by a high-data rate cable to the digital projector itself. You also have the major advantage of drastically reducing media duplication and shipping costs, too.

    This is moronic. This is annoying. I am beside myself with frustration. (Well, not really. --I don't actually care.)

    The fundamental truth of the matter is that the technology which is readily possible, and the technology which is actually made available to the public, are decades apart. After all. . , why nip the spirit of profit in the bud when you can produce and sell entire production runs of stone-age computer tech one incrementally advanced stage after another? Heck, this keeps the economy 'healthy' during peace times, ensures jobs and an appetite for more and more junk technology. "Planned Obsolescence" is reality.

    When everybody gets all excited about the big "new" thing, I groan. We're being led on and sold crap because there are miles and miles of money to be made between now and when the really good stuff is released, which of course, only happens when it doesn't matter anymore.

    So who cares? Just let me have enough technology to do what I need to do. Those needs were well met about five years ago, so honestly, I don't really care about any new so-called 'advances'.
