I'm looking at CD/DVD drives for a computer, and the upgrade from a 48x CD-RW / DVD-ROM drive is a 16x CD/DVD burner drive. Why is the upgrade from 48x to a lower 16x. What does the 48x and 16x even mean/ stand for?

The X means the reading speed or rather the pick up speed for the lens to read the disc. The drop in number is because both the X stands for different speed between CD and DVD. For CD, 1x is equal to 0.15MB/sec hence for a 48X, the lens is reading at 7.2MB/sec, so to say it will only need 1min and 51 sec to read a 800MB CD-Rom.
For DVD, 1x is 1.35MB/s , so 16X would be ard 21.6MB/sec however, a single layer of DVD can stored about 4.7GB, which is roughly 4812.8MB, so in order to read a full DVD at 16X would takes about 222.8 sec which is 3.7 mins.
Hope this helps u to get a better idea.

A conventional CD or DVD plays at 1x speed (that's what 1x is defined). A 16x speed simply means that the device is operating 16 times faster than a conventional CD or DVD. Therefore, 48x plays 48 times faster.
When you say upgrade to a 16x CD/DVD burner from a 48x CD-RW/DVD ROM burner, I guess this means that the 16x drive is capable of burning both CD and DVD, while the 48x one can only burn CD.

the DVD writer in the market that states 16X is refering to the maximum speed of the burning for a DVD discs. it means that if you have a 16X DVD-R or DVD+ R, the maximum speed of the DVD burning speed is 16X. As for the burning of Cd it will still be 48X in the DVD writer. the fastest in the market for the DVD-R and DVD+R is 16X. this therefore does not have anything to do with the CD-R. a CD-R will still be abled to be burning at 48X. so do not worry. the reason to show 16X is because it is to tell the user that the DVD writing function can be set to 16X.
As you might have known about the burning speed. the higher the 'X', the shorter time you will have to wait. so therefore it is the same theory concept. As such in the current market, the DVD Writers can only take in 16X as the maximum speed for a DVD discs are 16X. the burning speed of a CD-RW and CD-R speed will not be affected. what you had seen in CD writers will be the same in the DVD writers just that it emphasize the 16X for the DVD discs. so do not worry. the DVD writer is a better option to buy.

What you are seeing is the cd-rw writes to CD's at 48x and the new drive writes to DVD's at 16x, it is a different format to write to a DVD, currently I think 16x is the fastest however, the DVD burner will also burn CD's probably around 48x or more. Check the detailed specs.

The ratings refer to the speed at which the drive reads data off of a disk. Consult the wikipedia article below for more details, but in a nutshell the lower multiplier rating for the burner reflects how much more intricate and complex a device the burner drive is, as opposed to a drive that does nothing but read data.

basically 48x means it writes to the CD/DVD faster than 16x....the only down side is the faster you write to the CD/DVD, the less accurate (quality) you may have...12x is pretty standard. may take a little longer, but its worth it. especially for DVD quality!

You are comparing apples to oranges, CD speed scale is on a slower scale (abnout 7x CD speed = 1x DVD speed) but indeed, the DVD drive probably reads a bit slower for insertion of a CD,
