View Full Version : 400GB Blu-ray disc.

People were impressed when Konami and Kojima Productions managed to fill up an entire dual-layered 50GB Blu-ray disc with Metal Gear Solid 4. But 50GB discs? That's so passé. Pioneer has just developed a sixteen-layer Blu-ray disc that holds 400GB of data (!). With this kind of disc, your PS3 hard drive could be copied five times over, just for the heck of it.
Unfortunately, this impressive tech will not be compatible with your current PS3. However, the specifications used to manufacture these 400GB discs will allow any future reader that supports these discs to be backwards-compatible with older Blu-ray discs. We can already see the future: Final Fantasy XV on PS4, with over 2 weeks of cutscenes.

This is insane. Shame it won't work on PS3 though, PS4 here we come. It's gonna cost quite a bit if they put this in tech in PS4.
This is quite old news but still this is amazing for a disc, who needs hard drives when you have these.
It won't work because you'd need to manually redesign/adjust the laser in the drive. Being able to read/burn onto 16 layers is pretty damn impressive.

It all means nothing if they don't jack up the read speeds with it. Yeah more layers is impressive but give us a damn high read speed to go with it.

I agree. you can't make something this good and not speed it up, maybe technology just hasn't caught up yet.
I think the usual Blu-Ray drives you can get for your PC, read data from the disc faster than the PS3 drive can. Not sure, but if they had to make modifications to actually enable to laser to read 16 separate layers, I'd sure damn put a speed improvement on the top of the list.
It would take a hour or more (2<) with the usual speed to read something this size
One tiny scratch on that and you can kiss that disc goodbye.
MAKE SCRATCH-RESISTANT DISCS, DAMMIT.
I remember when CDs used to run near-perfect when you threw them through a brick wall. 10 times.

Blu-Rays are already scratch resistant. :P
I want them to be damage resistant, pl0x.

God mode Blu-Ray discs.
Blu-Rays are already scratch resistant. :PProve it to me. >:G

Hard-coating technology
Because the Blu-ray Disc data layer is closer to the surface of the disc, compared to the DVD standard, it was at first more vulnerable to scratches. The first discs were housed in cartridges for protection.
TDK was the first company to develop a working scratch protection coating for Blu-ray Discs. It was named Durabis. In addition, both Sony and Panasonic's replication methods include proprietary hard-coat technologies. Sony's rewritable media are spin-coated with a scratch-resistant and antistatic coating. Verbatim's recordable and rewritable Blu-ray Disc discs use their own proprietary hard-coat technology called ScratchGuard.

None of my games or Blu-Ray moves have even a single tiny abrasion. If a disk is dirty you can just rub it on your shirt and it still looks brand new.
Well, I meant like a video of someone taking a key to their disc and then playing it flawlessly.

I mean obviously it's not like they're hard coated with diamonds, but they can still get beat up pretty badly.
Thanks!
That's pretty good, to my surprise.

Think of the movie resolution they can get with 400GB. Amazing really.
Think of the hardware you have to develop to read movies at such high bitrates.

In a couple of years, that won't really be a problem.

Probably not. But 1080p TVs are just only starting to become more popular. You could only really take advantage of that 400gb limit if you have a display that can handle such high resolution and we're still years away from something like that becoming mainstream.

omg, 400GB??? that's insane. that's more than my computer can hold...2.5x to be exact. But I agree with everyone else. if the speeds aren't good, then what's the point?

It can always be a massive archive medium. I mean... if half/1 hour TV shows these days are around 170/350MB, that thing could store over 1000 episodes.

Having the entire running of shows on one disc... pretty convenient. No more boxsets for multiple seasons of a show!

That is actaully a great idea. I could see the PS4 using these discs as hard drives, maybe for games, who knows.
You can't have a optical disc replace a HDD. Seek time is slower which means the overall speed will be shit. Read/Write is slower by a mile, and i doubt they will make a disc that can be written on the fly in Milliseconds of response.
Only excusable replacement for a HDD is a SSD.

The next generation of consoles will probably have SSDs anyways, no doubt they'll be dirt cheap by then. And hopefully the makers will have the foresight to garuntee some sort of hard drive.

Bah, Nintendo are already looking into the next step with Hologram Discs.

The point is, when someone says they wish there was a 400GB disc, they could say "HA THERE IS, but it's pretty much useless. (Frowny face)"
But that is pretty impressive even though it doesn't seem like it can be used any time soon lol
lol with the PS4 they could make a value pack that contains EVEY PS3 game. lol
LOL imagine how long it would take to download 400GB rips of movies, wonder if anyone has the balls to even upload that on a torrent site.

That wouldn't be suspicious lol

Why not? It would take a couple of days on a normal speed broadband connection these days.
Balls? For what? If you mean law enforcement, they've already missed Petabytes of uploaded data from torrents.
If you mean Ratio wise, that's the users problem, not the uploaders.

A couple of days? Downloading at 1 megaBYTE per second, maybe. Downloading at 100kbps, it would take over a month. You'd need to be at a university or have a similar caliber connection to really do that...
Depends, the schools here in my country thanks to the Government have a supplied 1Gbit connection from ARNES.
Fiber optics give us dirt cheap connections up to 50 - 70Mb/s. Don't fell like paying for a 100Mb connection. Cable connections are around 25Mb max here. ADSL2 is twice as fast but not sure on those speeds.
You get similar stuff with Verizon's FTTH and i'm sure America has similar providers with similar speeds to what we get

Oh right, forgot you live in europe so you get crazy speeds for dirt cheap. Well, I'm pretty sure most of the US still has pretty crappy connections. Even when I'm on the university wireless and I open the floodgates on upload speeds, I still get max around 500kbps download speed.
I get about 700KB/s average on download speed (6mbit), and my upload is about 70 - 80KB/s (768K)
I took a look and it's averaged that USA has a overall better download speed for it's users than Europe, so i guess it's just some area's getting fucked for the price.

This could make it possible for an entire country in gta!
Yeah it's possible, but i'd hate to think about the development time, how many years of work to create a whole country in GTA :P
That would be completely pointless, I'd rather have one city done right.
