Panasonic LF-D311 DVD-R

4. RW reading tests

Panasonic LF-D311 IDE DVD-RAM/R - Page 4

RW reading tests

- Nero CD Speed v0.84 Test: (Click to see the CD Speed graph)

For the RW tests, we used Ricoh's 4-10x HS-RW media. The Panasonic's average reading speed with HS-RW media is 9.74X, which is lower than Ricoh's MP5120A:

CloneCD Reading Tests

- Procedure

We used CloneCD (v3.1.1.0) and 5 original CDs - Euro 2000 (SafeDisc 1), No One Lives For Ever (SafeDisc 2), Rally Masters (LaserLock 1), Desperados (LaserLock 2) and V-Rally 2 Expert (SecuROM 2) - in order to test the reading performance of the drive. We also tested its reading performance with backups of the original CDs, since the reading speed varies between the original and the backup media. The following pictures show the drive's reading capabilities:

- SafeDisc 1/2 Results

The Panasonic LF-D311 performed very well with SafeDisc protected CDs. The drive needs 6mins to complete the task but is slower than Ricoh MP5120A.

With SafeDisc v2.0 protected CDs, the Panasonic DVD Burner performed lower than with SD1 CDs but close to Ricoh MP5120A.

- LaserLock 1/2 Results

In the LaserLock 1/2 protected CDs tests, the Panasonic LF-D311 performs quite low, especially with the original CD...

- SecuROM Results

The Panasonic LF-D311 can read only 16bytes from Data/Audio tracks (and not 96bytes) of Subchannel Data. The drive's performance is very satisfactory.
