Sony Releases Quad-Layer 128 GB BD-R XL Media
Sony is about to start selling the industry's first 128 GB write-once BD-R XL optical media. The discs will also be the first quad-layer BDXL media formally aimed at consumers, but bringing benefits to professionals that use BDXL today.
Although the general BDXL specifications were announced back in 2010 for multi-layered write-once discs with 25 GB and 33.4 GB layers, only triple-layer BDXL discs with a 100 GB capacity (generally aimed at broadcasting, medical, and document imaging industries) have been made available so far. By contrast, quad-layer 128 GB media has never seen the light of day until now.
As it turns out, increasing the per-layer capacity of Blu-ray discs (BDs) to 33.4 GB via a technology called MLSE (Maximum Likelihood Sequence Estimation) was not a big problem, and most of today's BD players and optical drives support the BDXL standard. However, increasing the layer count to four while ensuring a broad compatibility, signal quality across four layers, yields, and some other factors slow downed release of 128 GB BDXL essentially by eight years.

Streaming hasn't completely killed the optical disc. The Blu-ray Disc Association has completed the Ultra HD Blu-ray specification. New Ultra HD Blu-ray discs will support 3840×2160 "4K" resolution at up to 60 FPS using H.265/High Efficiency Video Coding. It also supports the larger Rec. 2020 color gamut, which allows for colors of greater saturation to be reproduced. 10-bit per channel color depth is supported, increasing the number of possible colors to ~1.07 billion (10243) from ~16.8 million (2563).
The specification defines discs with capacities of 66 GB and 100 GB. This means that the 33 GB per layer, triple-layer technology of 100 GB BDXL discs will reach consumers.
Tom's Hardware notes:
With a new spec also comes new Ultra HD Blu-ray players, which is a bit of a concern. Fortunately, these new players will have backwards compatibility with Blu-ray discs. However, those who have been using a traditional Blu-ray player for some time will just have to replace it with a model that plays Ultra HD Blu-ray, and those who use the PlayStation 4 or Xbox One for Blu-ray content are stuck unless they want to add another space-hogging box to the living room.
Licensing for Ultra HD Blu-ray begins this summer, but just like 4K content and TVs, it will take some time to see wide adoption. The TVs are already here, but the amount of content needs to increase in order for users to justify the cost of purchasing new 4K devices.

Did you notice that Samsung hasn't made a peep about Blu-ray players at CES or other recent trade shows? There's a good reason for it: the company is exiting the category in the US. Samsung told Forbes and CNET that it's no longer introducing Blu-ray players for the country.

The problem is they are rapidly being eclipsed by newer tech. Yes you can buy 100GB triple layer BD-XL now, but look at the price tag, then compare to a flash drive. If they can't move these new 128GB blanks at a price competitive with 128GB flash sticks they are going to have a problem. It is a chicken and egg, lowering cost requires volume but volume manufacture needs people willing to buy. And all of the larger BD blanks are write once, flash is at least "write a few times before it craps" media. The claim is optical media stores longer but we, by definition, have no actual track record with any of these new formats. The fact the spec already calls for (translated from tech to English) making scientific wild ass guesses as to what was originally recorded, that they are riding the ragged edge of being able to recover the data a moment after it is first written does not inspire confidence that it will still read decades later.

They say these discs will run $10-11 each. 128 GB USB stick or microSD storage seems to be in the $20-30 range, so it is competitive, ignoring the Blu-ray drive needed. Also ignore hypothetical higher data retention for the optical disc, or the question of rewritability.

Not if you buy whatever is on sale that day. Today it is Samsung 128GB for $17.23 at NewEgg. And by the time these new BD discs actually show up in volume flash will have almost certainly dropped again. There is also the transfer speed advantage most of these newer flash sticks have over optical media.
Buy yeah, optical needs to up their game and go TB or bust. Until recently optical media's attraction was being bigger than other commonly available storage devices. That stopped being true with BD. Think about it. When CD-ROM came out the yuge 600+MB storage was game changing, enough people were quite willing to put up with slow access, high cost and for several years requiring pressed "mastered" media. Was living in Dallas and we had at least TWO stores specializing in only CD-ROMs. One, simply called "The CD-ROM Store", is where I got my first Yggdrasil Linux install media. When DVD hit in the late 1990's putting several GB on a disc was again a big win. By the time BD showed up, 25-50GB was already meh and in 2019 128GB is going to be super meh. Upper end phones have 128GB and probably another 256 in the MicroSD slot if they have one.

Most people don't have a few thousand TBs of data to store. The economics of storage have also been changed a lot by cloud providers. I back up my laptops to a FreeBSD NAS and then use zfsbackup-go to store the data in Azure (encrypted using PGP). That costs $10/TB/month for cold storage, a bit under $2.5/TB/month for archive storage (archive storage may take a few hours for recovery). Azure can provide such cheap storage because they buy really, really cheap disk drives with high failure rates and put error correcting codes across devices [sigops.org]. You need a lot of independent drives to be able to do that kind of reliability above the device level and so that's hard for anyone to compete with locally. Companies like AWS and Backblaze are constantly trying to push their costs down to compete and that helps keep the cost low for the entire market.
Optical disks have failed as backup media for the last few generations for a few reasons. The first is that the CD-R was the last optical disk that, at launch time, could back up an entire consumer hard disk. When DVD was announced, about 20GB was larger than most hard disks but by the time DVD-R (and the three competing kinds of rewriteable DVD) were released they were initially single-sided, single layer (4.7GB) and hard disks had grown to around 40GB. Blue Ray launched at 25GB/side when disks were hundreds of GBs upwards. I actually bought a BD-RE drive and a little stack of disks for it almost 10 years ago - I've never even got the disks out of the pack because nothing I want to back up fits on a single disk and the effort of doing something like par2 archives spanning multiple disks is too high.
The second thing that hurts optical disks is the high cost of the drives. BD-RE is now pretty cheap, but at launch time the drives typically cost about the same amount as a decent-sized disk. This means that you need to be storing at least 2-3 disks worth of data for it to make sense to buy a writeable optical drive. CD and DVD readers helped get economies of scale up by having a useful second function: being able to play audio CDs and video DVDs on a computer. BD screwed this up by putting such insane licensing restrictions around their broken DRM scheme that hardly anyone ever bothered. If it had been easy to play and rip BD disks then this might have been different. This is exactly the same problem that tape has had: the drives are so expensive that they don't make economic sense for small users, which means that they never get the economies of scale, and that keeps the costs high for the entire lifetime of the device.
These disks are costing a bit over $10 each. That gives me 128GB of backups, but with no redundancy. If you want off-site backups, you need to find somewhere else to store them and, realistically, if you care about your data then you're going to want to store either multiple copies or error correcting codes. If you're storing them off site, then the recovery time includes the time to get them back from wherever they're stored, so archive storage is a similar latency, so they're competing with $2/TB/month. That means that the cost of the disk (alone, not including the cost of the drive) would buy you about 3 years of cloud storage for the same data. You can write to the cloud storage from any number of devices independently, you don't have to change disks, the redundancy is handled for you (and you can pay for more if you're paranoid - I don't, because the probability of Azure losing data at the same time as the RAID-Z setup in my NAS dies seems vanishingly small - the main threat model that I care about is a thief breaking into my house and stealing everything that looks like a computer), and the physical storage is handled for you.

Relied on a two laser configuration that never became affordable. As far as I remember hearing the tech all worked, but after the failure of HD-DVD, which they were most compatible with, the holographic disc standard was decided to not have a future with hard disk and flash drive capacities taking off. They would have used red/green lasers instead of the blue/purple lasers of the bluray based tech. One laser had to be higher wattage for the holographic phase change, while the other was used for reading both traditional and the new media.

Ten or fifteen years ago I would download various TV episodes and movies to my PC. Every 2 or 3 months I'd cleanup my hard drive, and burn them to DVD+R single layer disks. Back then I had a DVD player that could read DIVX and XVID, so it worked great. The main downside is it would take several hours to group all the files, rename, and burn one disk at a time.
At some point buying the blank disks and spending a Saturday afternoon archiving files wasn't worth it anymore - hard drives were too cheap. Since then I moved onto a synology NAS, and more recently a qnap NAS. No renaming, burning, searching for the one disk you are missing buy can't find - just navigate the network drive and you will find it.
On a related note, I still have yet to have a drive or player in my house that will play BluRay disks. Between streaming and all the various HD file formats available on certain corners of the internet, I highly doubt I will ever have a need for one. But then again I do like sticking it to Sony...

Another thing is the failure mode of flash and HDDs, more often than not it is the controller hardware sitting between the motherboard and the actual bits that fail, not the bit surface.
In contrast optical media, much like floppies of old, can easily be moved between RW hardware if it fails.
Now if we had optical media that behaved like a floppy (drag and drop, written and deleted sector by sector), optical media may be an interesting option again.

However those at least have one purpose: Providing individual or customized production runs of media for people who want a physical copy as proof of license/ownership.
The currently available models are DVD, 25GB BD-R, and 50GB BD-R. 100GB BD-Rs are only available as standard optical media, but the costs are in-line with the M-Discs, despite the much shorter expected lifespan of the media. Given the burn times of the current optical media, the only people it makes sense to purchase these or the drives are people who need semi-immutable data in the event of an apocalypse scenario, who might need to survive both EMP and gaussing magnetic blasts. In those events however, either the equipment needed to interface with the media will be destroyed whether hard disk or optical, or the devices will be kept somewhere insulated enough not to be affected either way. At that point the only benefit to the optical media is that it might last a few hundred years if necessary without significant data corruption. Only the drives and computer systems wouldn't last that long due to flash cell degradation. And since rom alternatives aren't available on all but the oldest hardware, getting a bootstrap environment to reflash newer devices if their firmware is corrupt would be next to impossible, even with the documentation.
Technological bootstrapping kits needs to be a techie priority lest some event happen that pushes us into a modern dark age. Enough of our technology is proprietary or insufficiently documented that recreating the intervening bits, or the bits needed to recover newer devices or processes would be impossible without reinventing the wheel, assuming tech crashed back to a 1950s or earlier level.

Whenever the M-DISC version comes out, they should theoretically last well past a century with almost zero probability of the type of "bit rot" you're talking about, which happens to cheaper media like organic dye based discs. I had a nice complete box set of Stargate SG-1 DVDs I got from Cosctco about ten years ago. A few years later at least a third of them were full of glitches or unreadable. M-DISC (Millennial disc) is interesting because it claims to use a non-organic, mineral based substrate that is highly resistant to damage from UV, moisture or temperature variations that will quickly destroy normal optical discs. Seems to mostly Verbatim marketing them.
Besides M-DISC media and some "gold archival" stuff, I haven't seen any optical media that claims to reliably hold data more than a decade at the very most. Sadly, the same goes for offline spinning hard drives and all flash media and SSDs. Many solid state drives will start to lose data within a few months, hard drives within a few months or years. Well, there's tape media, which should last quite a long time and be readable even with a few errors if you use error correcting formats. But getting into tape in a useful capacity is very expensive.
Then again, M-DISC is quite costly as well. Ten regular 100GB BD-XL discs are $50 ($5 each), just five M-DISC 100GB BD-XL discs cost $85 ($17 each). I won't be surprised if the 128GB M-DISC BD-XL will cost about $20-25 per disc. Still, in my research I haven't found any other reasonable alternatives for truly long term archiving of large amounts of data.
But yeah, don't even bother with the non-M-DISC version of any optical media. And the largest capacity gold archival media I know of is just basic 4.7GB DVD-R discs. Not that useful these days.

The cheap, probably garbage discs that I *can* find, which in my experience probably won't last ten years if they're sealed, untouched, in a vault...those discs are still more expensive per gigabyte when buying in packs of a hundred than a large hard drive. Hard drives can fail too, but in my experience getting one to last a decade shouldn't be difficult, especially if it's powered down.
Hard drives are also going to require less physical space than that stack of discs, so they'd give better bandwidth for that 747 too. Plus you won't have to sit through "Please insert disc number 103 of 200..." while writing your data! And it's re-writable, which is a nice bonus...
