difference between various "dual drive" (DVD/CD-ROM) options?

I'm in the process of customizing a tentative new Dell for myself, and am wondering what the difference is between the following:

Dual Drives: 48x CD-ROM Drive + 48x CD-RW Drive [add $20]
Dual Drives: 48x CD-ROM Drive + 48x CD-RW/ DVD Combo Drive [add $50 or $1/month1]
Dual Drives: 16x DVD-ROM Drive + 48x CD-RW Drive [add $20]
Dual Drives: 48x CD-ROM Drive + 16x DVD+/-RW w/dbl layer write capability [add $100 or $2/month1]
Dual Drives: 16x DVD-ROM Drive + 16x DVD+/-RW w/dbl layer write capability [add $100 or $2/month1]

Is anyone willing to enlighten me?
Thanks!

 

The first is a read only CD drive with a CD only burner.
The second is the same except that it can also read a DVD but not burn one.
The third is basically the same as second but with a different setup. Go with this one before the second.
The fourth and fifth are basically the same with different configurations. Personally I'd go with the fifth.

 

Hi Jay,

No - the fourth Dual Drives: 48x CD-ROM Drive + 16x DVD+/-RW w/dbl layer write capability [add $100 or $2/month1] the first ROM is CD read only.

The fifth - Dual Drives: 16x DVD-ROM Drive + 16x DVD+/-RW w/dbl layer write capability [add $100 or $2/month1]
the first ROM is DVD read capable.

Agreed, the fifth option is the same money, so that's the way to go if dual drives are ordered.

You're right that they are actually different but I was basically just looking at 1 ROM and one burner.

Bottom line is we both agree that #5 is the way to go.

 

Thank you kindly, gentlemen! I'll take your advice.
