Theoretical write tests:
First we’ll show two shots from Nero CD-Speed.

Here you could clearly see the shifting points to the Mitsumi drive. As this picture shows it’s a Zone CLV drive.

And this shot shows the Zone CLV speed of the Lite-on.
Well, the Lite-on is a tiny hair faster and wins this test.
Real life write and read tests:
Here we’ll read the same disc to an image and then write it back using various different programs. We use a disc with 80 minutes and 25 seconds with data on and then write it onto 24X certified MPO produced CD-R discs, here is what CD-R identifier could tell about them:
- ATIP: 97m 25s 07f
- Disc Manufacturer: MPO
- Reflective layer: Dye (Short strategy; e.g. Phthalocyanine)
- Media type: CD-Recordable
- Recording Speeds: min. unknown – max. unknown
- Nominal Capacity: 702.69MB (79m 59s 00f / LBA: 359775)
Program | Mitsumi read | Lite-On read | Mitsumi write | Lite-on write |
CloneCD | 2: 48 | 2: 41 | 4: 02 | 3: 48 |
CD-Mate | 2: 50 | 2: 42 | 4: 04 | 3: 56 |
Nero | 2: 48 | 2: 41 | 4: 01 | 3: 49 |
The Lite-On comes out as the fastest drive in this test.
CD-RW writing and packet writing:
How good are they at handling CD-RW? The Mitsumi has a speed advantage since it supports 12X Writing, but how much could this be seen in practical use?
What? | Mitsumi CR-4809TE | Lite-on LTR-24102B |
Write a full 80min CD-RW | 8 minutes 21 seconds | 8 minutes 28 seconds |
Quick erase 80min CD-RW | 24 seconds | 34 seconds |
Full erase 80min CD-RW | 8 minutes 32 seconds | 8 minutes 51 seconds |
Both drives worked perfectly using Ahead’s InCD packet writing software. We did not run many test but the Mitsumi seemed to be a hair faster.
