Here are the specifications for the Audigy Platinum eX, which contains everything all the other packages have and more.
This time around, Creative has released two different Platinum flavors to choose from. The vanilla Platinum includes the AudigyDrive, a panel that fits into a standard 5.25" drive bay in your system case, similar to the Live!Drive that Creative bundled with its Sound Blaster Live! Platinum. While this approach gives you more features, it also has the questionable benefit of having a number of cables hanging out the front of your computer. Also, the accessibility of the internal Audigy!Drive depends on the placement of the computer chassis. For this reason, a Sound Blaster Audigy Platinum eX with external AudigyDrive breakout box is also available.
The SB-1394 internal and external connectors are available on every Sound Blaster Audigy card, whether it's in the MP3+ or Platinum eX bundle. It's also important note that the SB-1394 supports non-Creative Labs devices as well as Creative's own. This means that a FireWire CD-RW, hard drive, DV camera or anything else can be used (but more on this later).
