The specifications of Panasonic SW-5582 state that the drive is able to write CD-R discs at 24x and CD-RW discs at 16x. Let us find out how the drive really performs in speed and quality.
Writing Quality with CD-R discs:
For our data writing tests, we simply set up a new compilation of about 702Mb using Nero Burning ROM software. Writing method used is DAO (Disc At Once), and the disc is set up as a non-multisession disc with 'finalize disc" enabled. The screenshot below shows how long it takes to write a disc at the highest speed (24x):

The drive took 4 minutes and 46 seconds to write the disc at 24x.
Write Quality:
We will test CD-R discs from different CD-R manufacturers. To really measure the write speed, we used the 'create data CD" function in Nero CD-DVD Speed. The discs were written at the maximum speed that the drive supports. For the quality test, we used K-Probe 2 which is a tool developed by a Lite-On employee. It runs under Windows and works with drives made by Lite-On. Also note that different drives and different reading speeds may affect the results obtained when scanning the discs. We used a Lite-On LTR-40125S drive with firmware ZS0R and scanned the discs at 48X speed.
A written CD-R disc will always have some C1 errors; C1 errors are easily corrected by the drive's error correction capabilities. The next level of errors is C2, while C2 errors could also be corrected by most drive's error correction capabilities; they are not wanted on a good quality disc. A good disc should not contain any C2 errors, and preferably have an average C1 error amount of below 2.0 for the best quality discs, or at least below 10.0 C1 average for good quality discs. After C2 errors, there are only un-correctable errors that will make a disc unusable.
In short, our analysis will be based on these guideline to determine the quality of the burned disc:

Writing Quality with CD-RW discs:
We will add a few write quality tests with re-writable media. Settings and testing procedures is the same as used earlier in this review, so you may want to go back and read them if you are unsure. All discs used for these tests are new and have not been written to before.
