I'm not totally sure about it , but arent blue ray discs 5 gigs of capacity and xbox discs 4.5 gigs ? So how could a blue ray disc only use one disc for blue dragon when there is only 500 mb more space on it ?? The capacity difference between blue ray and Xbox discs is really not that big , people talk about it like its 10 times more .
LoL, dude.. its more than you think.
Single layer on one side: 4.7 Gigs
Dual layer on one side: 8 Gigs
Physical size Single layer capacity Dual layer capacity Quad layer capacity Sextuple layer capacity
12 cm, single sided 25GB (23.3GiB) 50 GB (46.6GiB) 100 GB (93.2GiB) 200 GB (186.4GiB)
12 cm, double sided 50 GB (46.6GiB) 100 GB (93.2GiB) 200 GB (186.4GiB) N/A
8 cm, single sided 7.8 GB (7.3GiB) 15.6 GB (14.5GiB) N/A N/A
8 cm, double sided 15.6 GB (14.5GiB) 31.2 GB (29GiB) N/A N/A
So 25 Gigs as a starting point. With 200 gigs probably being an incredibly expensive disc at the moment.. and cheaper 5 years from now, the same as buying a dual layer DVD to burn on a couple years ago.
Anyway, 25 gigs as a starting point is just ludicrous for games. Only benefit would be movies, as reality on film uses so much space. Less so for animation, black'n'white flicks like Sin City, etc etc. The more colors, the more movement.. an extra audio channel or two.. and you use up space relatively quickly. DVD is a space-limited format because the rules state you have to caiter to extra languages.. spanish, french being the usual additions... and if you throw a DTS track in, maybe an hour of extra's.. your movie quality takes a huge bump on a dual layer disc, let alone a single layer. WHEW!
25 gigs = 3x the storage of any given DVD movie. maybe 3x-12x the size of most games these days. Space is BARELY an issue for games, as I said previously.
200 gigs = 25x frickin' times the storage of your average DVD, if it was packed to the gills.
However, you have to consider a great damned lot of that space is going to be used up pretty quickly. A nice quality HD stream can pack 10 minutes of film into 1 Gig easily. So 25 gigs? Sure, lets say 250 minutes of HD grade video. Lets cut off 50 minutes for menu's and extra's. Now, consider an extra 50 minutes for top notch audio tracks in all the major languages. You have 2 hours and change for your average movie. A perfect fit for movies.
Games? Honestly most games dont even use their DVD's worth. Its completely acceptable to release multi-CD games on PC because CD's are pennies to make and games dont TAKE UP SPACE! Just like the first PS2 games were on CD's sometimes, I expect a great many PS3 games to be on cheap DVD's.
People werent happy with laser discs and videocassettes, but the jump from DVD to Blu/HD DVD's is like the change from windows 95 to 98. The change will be slow and sony is foolish to force Blu-Ray on the market and take such a massive loss per console when HDTV's still arent your average household item. Component inputs, maybe.. but HDTV resolutions? Have we reached a point where a small scratch on the Blu-disc can kill a gig of info? lolol
We'll find out in 2007. Although I've heard PS3's are overheating, already. Sheesh, first generation consoles are always such crap. 2007's batch should be stable.
