Lite-On SOHR-5239V Review

CD-R Writing performance


In the specifications of the Lite-On SOHR-5239V we ca find that the drive supports 52x writing for CD-R media. Let us now find out how the drive really performs.

For our data writing tests, we simply set up a new compilation of 703Mb 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. (52x)

The Lite-On SOHR-5239V took 2 minutes and 37 seconds to complete the burn at 52x speed.

CD-R Writing 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-Speed. The discs were written at the maximum speed that the drive supports. For the quality test, we used KProbe 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.

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 discs, or at least below 10.0 averages for good quality discs. After C2 errors, there are only un-correctable errors that will make a disc unusable.

Below are the obtained results:

Overall thoughts:

The Lite-On SOHR-5239V burns CD-R media with very good quality but has sometimes problems to burn media at their full rated speed. We assume that a firmware update would also save this problem.

Now let us check if the CD-RW writing performance is as good as the CD-R writing performance…..
