Kenwood's 72X True X CD-ROM Drive
No "specsmanship" just performance!


Once in a blue moon, we get a product in here at Hot Hardware that absolutely knocks our socks off. It doesn't happen very often and we test a lot of product every month. This is one of those times. For many of us, CD-ROM drive technology has matured to the extent where we are beginning to reach diminishing returns on our investment in next generation technology. Today's 48X and 52X drives are hardly faster than there 32X siblings from days gone by. DVD ROMs and Re-Writable Drives are still making good strides in performance but the standard CD-ROM is somewhat lack luster.

Now I am going to ask you to throw that notion out the window and forget you ever thought that way. Or should I say, Kenwood is trying to change your mind in this respect? The outside of the box for the Kenwood 72X True X CD-ROM says this "the worlds fastest CD-ROM drive". Guess what? They are dead-on right.

Beam me up Scotty.   There is too much intelligent life here...

With specs like this, it has to be the fastest there is, right? Well, as we all know CD-ROM drive manufacturers play a huge game of "specsmanship" when it comes to rating their products. One 48X drive can perform close to 28X levels and another can perform like a 12X drive with both products having the same numbers boasting performance levels far different than reality. Kenwood uses the word "True" in their product for a reason. Here is the technology behind the performance numbers and why the drive speaks the truth.

Being from the Semiconductor Industry, I spend time with a lot of Electrical Engineers every day. Most are fairly intelligent folks. When I have the occasion to meet with Optical Engineers, I am usually blown away by their brilliance. These folks deal in almost a sort of "black magic". It is truly "deep" stuff. We'll spare you the physics here folks and keep things crisp. In short, what you see in the above diagram is the way the 72X True X CD-ROM Drive's Lasers are split into to seven discrete beams and track across the disk. This allows for 7 parallel reads on a rotation and thus incremental gains in throughput.

The "7 beam pick-up" as Kenwood calls it, is a patented technological marvel.

It also allows for lower disk rotation speeds as a result. This drive is one of the quietest drives I have ever tested, period. It is as quiet as most 4X drives so long as you have it mounted correctly so there is no rattle in the case around it.  

So far so good. As we all know however, the proof is in the benchmarks. All of these wonderful features wouldn't mean much if the drive couldn't live up to its claims in performance.
