Title: Xbox 360 Dvd - Only 7gb Of Data Useable?
Post by: {Sephiroth} on September 09, 2005, 11:58:00 AM
According to the news on the home page only 7gb is useable by the 360 for game data. This is worrying. Anyone know why, or is there somehting I'm missing?

well a typical dual layer DVD holds 8.3GB after formatting

If it's anything like the current Gen Xbox MS has arbitrarily capped the amount of storage they can use so that the outer edge of the disc can receive damage without loosing data.

Also we have no idea how much space might be lost to any mandatory data encryption, dash-updates etc.

Thats worrying. 9GB may not be enough let alone 7. PS3 has Blu-Ray which is many GB per disc, but 360 only having 7gb as its maximum storage for games is ver very worrying. That could just about hold Jade Empire

I thought Bethesda said theyve only filled 6 gigs worth and have about "3" left, so the current format is more than enough. Last I checked, 6 and 3 = 9.

I can find the video interview where the lead designer says the disc does hold 9. I just remembered he said 9 gigs. I doubt hes lying, but wtf do I know.

who knows... though it was translated from a 3rd party japanese source  :lol:

What I found most interesting was this:

QUOTE
-In a double-layer DVD for Xbox 360, 7GB is usable by a game. The transfer rate of the DVD drive is 15MB/sec max, 10-12MB/sec average. The seek time is 115ms, switching layers takes 75ms. Loading 512MB data takes 34 seconds.
-2GB in the HDD is used for a temporary cache area for games. Its average transfer rate is 17MB/sec and the average seek time is 13ms.


Once you get past the seek time the DVD drive is capable transferring almost as fast as the HDD... though "on average" it's 1/3 slower... so if it takes 15 seconds without the HDD it will take 10 seconds with it...

Not to mention this is the same "speed increase" most found with the ATA100/133 cable upgrade so those that didn't notice a difference have nothing to worry about when playing without a hard drive  :lol:

Nothing keeps the developers from using multiple DVD's.
Don't forget that PC games will have to fit on DVD's too for the next years.

 :rotfl: Yeah, since they just started using them. I was so fucking sick of 6 CD games. :lol:

The reason why the space bothers me is very simple. The system isnt even out yet and games are about to burst off the 9GB disc. In a few years that could be bad. Here is an example. First Generation PS2 were mostly on CD (650MB) and the ones that were on DVD were only about 1GB. Well, now PS2 games are starting to be dual layer.......it went from games fitting on one CD to games just fitting on a 4.7GB DVD to games on Dual-layer 9GB DVD's. I really don't want multi disc xbox 360 games. Since I want next generation to have more games with free roaming enviroments or very large scale enviroments, I dont want to have to change the disc to get from point A to point B.

The thing about PC games is that they have to be installed and so are compressed on the media they come on (I think...)

To be completely honest I believe the only games this will effect is huge RPG's like Elder Scrolls 4 (but not Elder Scrolls 4 itself). This shouldn't affect first person shoters or any other genre. And really its perfectly acceptable. But just 7 gb worries me

Hmm ok part of the Japanese site (where it came from originally and the other site didnt translate this bit for some reason) appears to be confused about the 7gb by saying "The remaining 1.5gb for system usage/function?"

I hope that this article is incorrect and it's just the Japanese trying to cripple MS by saying their next gen system cant handle anything released 2007+ (which is basicaly what a 7gb limit would do, unless some people come up with some amazing compression techniques for both audio and textures)

I'm not too worried about having to hypothetically, in the future, have to change discs after some hours of smooth playing, what really worries me is to have to play something on new technology discs not yet optimized and having to "loading..." stare "loading..." every "loading..." ten "loading..." minutes "loading..." a boring "loading..." screen for "loading..." something to "loading..." load =)

Lol yeah the 360's DVD drive is only 2mb/sec slower than the HDD. You seen the article about MS supporting FVD? Do you reckon the 360 will be compatible with it? Because if the 360 media could hold 15gb I would be perfectly happy. Thats sufficient for this upcoming generation. Obviously most games would still be on DVD but for the few that need it that would be perfect.

I reckon they may be incorporating that into the 360 for future use. Hmm I was always suspicious how Elder Scrolls 4 fit onto the 360 DVD discs...

this is another reason that the xbox should have a hd-dvd drive, even if it doesn't take off it still has the potetial storage.  Iono if it will be a big problem for games for the first 2-3 years.  i mean i don't know if its shrunk or not but like new releases of Rainbow six and stuff are only 2.5gb, and ur right, only rpg's come to mind when thinking of dual layer (like jade empire) and i mean halo 2 was only ~4.4gb.  Later this may be a problem tho, but then theres always the posibility of a good compresion sceme that uses the extra cores in the cpu (like u'll still see load screens but it will just decompress into ram and then ur good to go).  And u guys can't really make a comprison to pc games w/ multiple discs.  when u have a hdd that u can put everything on, it doesn't matter how may discs u have, but when u have none it does.  i mean if the dev's knew that all 360's had hdd, they could say, have u stick in the disc with the levels, which would off load them to the hdd and then play the engine off the dvd.  but either devs will have to deal by useing some creative way, or there will have to be hdd only games.  as for the hdd being almost as fast, that is understandable.  i mean laptop drives are notoriecly slow (escially the cheaper one with low low rpms)  but they will always have higher sustainable read mbs/s and they also greatly benifit from seek times.

FUCK! , so i dont really get a 20GB for me just 18GB and HD's not always brings 20GB just around 19GB , so that would make around 17.5GB for me , they better offer me exactly 20GB damn it!!.  :grr:

1. Any game that doesn't compress the files on the DVD either reads VERY small files or doesn't realise the benefits.

2. The DVD/HD read speads are comparable and thus interchangeable when it comes to design

3. DVD9 is de facto 9Gb... ALL games have a section of data on the disk that is NOT part of the game. MS games are no exception.

4. 7GB is plenty, heck my last two games fitted into 1.4Gb and they were pretty big.

MS Creating New DVD Format     FVD-1 and FVD-2.


MS has been pushing Windows Media 9 into non-PC applications with an eye towards playing a larger role in the consumer electronics arena.

For example, researchers at the Optoelectronics and Systems Laboratories (OES) of the Industrial Technology Research Institute in Taiwan announced in April an optical disc format called FVD (Forward Versatile Disc), which was developed as a low-cost disc format for high-definition video.

The first version of the new format, called FVD-1, can hold 5.4GB of data on a single-sided, single-layer disc and 9.8GB on a single-sided dual-layer disc. A second version of the format, FVD-2, will offer more capacity. A single-sided single-layer FVD-2 disc can hold 6GB and a single-sided, dual-layer disc can hold 11GB of data.

By comparison, standard DVDs hold around 4.7GB of data and the EVD (Enhanced Versatile Disc) format, developed by researchers in China, can hold around 9GB of data.

Unlike the DVD and EVD formats, FVD supports Windows Media Video 9 and Windows Media Audio 9 Professional. Using Windows Media Video 9, FVD-1 discs can hold up to 135 minutes of high-definition video, enough to encode most feature-length movies on a single disc, according to OES.

The first FVD players will hit the market during the second half this year.





Even so, FVD-2 with 11 Gbs, thats shit.  In comparison with Sony & Toshiba's DVD war anyway.

But, Samsung and MS have paired up ALSO, and samsung/toshiba are the same, arent they?  Which would mean maybe MS will take the HD-DVD and give it FVD and maybe ....360 add on??   Multi-Disk games are the only other option.


fuck.

I find that statement hilarious.  During the effort to cut piracy, MS releases a new DVD that hold more than enough to copy any featurelength movie DVDs and most uncompressed feature lenth AVI's.  ahahahaha.  oh well.

Or new compression technology and not using cgi cutscenes, which MS and devs has already talked about.
The main thing that kills space on discs are the CGI cutscenes, but MS and Devs have said that there is no need for cgi since they can now make cutscenes in realtime using the games engine (look at Gears of War, Dark Sector, Prey, Oblivion, Kameo, Amped 3, etc).
Some games will still have cutscenes, like Japanese RPG's and games which are on platforms which require cgi cutscenes (current gen consoles), so those minority of games will just get closer to the maximum space on the disc. Some Japanese Rpg's will exceed the max space on a dvd, not necesarily because of the size of the game, but because of the hd cutscenes. They will have 2 discs to run from, which many rpg gamers are used to (Ie. Insert cutscene disc).

FVD is 15 GB max not 11, which definately is more than enough. Will FVD work on a standard DVD player? In which case MS need not make any hardware adjustments

Title: Xbox 360 Dvd - Only 7gb Of Data Useable?
Post by: twicked on September 10, 2005, 09:40:00 PM
doubt it, FVD is a new technology and will require hardware notifications to be able too read.  Which is why MS is putting them into DVD players and such so that they can extend WMV tech to the world outside of PCs.

Anyhow, either way I think they may try to throw some Samsung FVD DVD players into the 360.  I Assume they will read all other media aswell.

but maybe not, who knows?

Post by: m_hael on September 10, 2005, 09:44:00 PM
the thing about MS is that they CAN upgrade firmware whenever they want... if FVD and whatever its called (never heard of it) requires a new firmware then they'll ship a new XDK (software) with the firmware within.

Post by: twicked on September 10, 2005, 09:46:00 PM
I wonder... they have all the security, right?  Then perhaps they can flash the firmware over the net, like an AutoUpdate..  they might even be able tyo zero your HDD  :blink:  AHahaha, oh well.

Anyhow, keep up the thinkin.

Post by: {Sephiroth} on September 11, 2005, 02:25:00 AM
I think maybe FVD requires slightly different hardware. The only similarity is they both use red lasers, but a DVD player wouldn't know how to read it.

As it happens though I don't think the slight modification to the hardware would cost much or take much time. This may well be included in the 360 for holding gam data, just for that extra little bit developers may require.

Can't they just make 8 layered DVD's??

A drives ability to "read" is part hardware part software (firmware)... if its possible then its likely to be a firmware chane.

As FVD is basically ready MS can include that with the 360 already
