I don't know if this is in the right section, and it has probably been asked many times before, but what is the difference between a blue PS2 disk, and a standard silver/reflective one? I would be glad of someone's help!

The Blue dye surface performs just the same as the silver disk.
The only difference is the color of the dye.
There is no problem with that except, that, the difference of the color dye is
just the difference between lasers. The laser affects how the CD dye is read.
However, if you asked for the difference between a gold and a silver, the difference is greater. Silver is more reflective than gold, but silver is more subject to being corroded by the dye and (over time) other environmental factors. On the other hand, silver is much less expensive and there are ways of addressing the corrosion issue. Gold does not corrode easier, and lasts longer, but gold seems to be more expensive than silver.
There are groups of dye: Silver/blue silver/blue and gold/green.
Following: you don't have to read this, but its about the three common dyes that are in use today.
[There are three common dyes in use today:
"Cyanine," the blue-green dye used in many less-expensive CD-Rs, has a lifespan of between 10 and 75 years, which puts it at the bottom of the dye-lifetime scale. In a word, if you use these CD-Rs, be "conservative" in how long you expect it to last.
"Phthalocyanine," on the other hand, is the longest-lasting dye, producing golden-colored CD-R disks which have, "....a reputed shelf life of something like 100 years."
Finally, with dye lifetimes falling between those two, we first find the greenish-gold "fromazan" that produces CD-Rs with a somewhat better lifetime than cyanine. We also find the dark blue "metallized AZO" CD-Rs, which exhibit a lifetime more towards the higher end of the scale.
As we can see, the type of CD-R we buy can significantly affect the longevity of our data --- but you may have noticed that few CD-R packages disclose their chemistry! ]

Blue= CD, holds less, colored.
If you have a swap magic you'd know.
No.
Wrong. DVD's can hold much more than a CD.Wrong, a blue CD can hold more than a silver one.
It depends on how it is made.

Silver = DVD
Blue = CD-r
First thing. It's Blu-ray ( BD-r Blu-ray Disc recordable)azurith said:The PS3 is 'supposed' to be shipped with BlueRay technology.. that is, the ability to READ the new disc format..
It won't change a bit. In fact, most games for the PS2 and Xbox aren't even using half of the storage of a normal DVD disc. I popped in my SOCOM 3 disc and it was only about 3.4gb while a DVD disc can hold about 8 gb. There is another game, .. I can't quite remember it. But it was a HUGE game. Lots of cutscenes, hours upon hours of gameplay and extremely large worlds and it only had about 700MB on the disc.azurith said:Think of the possibilities for games, when you have 4-5x more storage than the current DVD format!!!)
