- CD Format
The Pioneer K14L supports maximum reading speed up to 24X for CD-R and CD-RW media. What follows is a graphic representation of the K14L performance compared to the other two drives:



The Pioneer drive came last using Pressed CD, second using CDR media and first, using USRW media, all in comparison to the other two slim drives...
- DVD Format
Using Single Layer media, the Pioneer drive, reported high speeds, not high
enough though to beat the LiteOn slim drive. Using the PTP (Parallel Track
Path), a Dual Layer media, the Pioneer drive gave out the best results,and
finally in the OTP (Opposite Track Path) case, again a Dual Layer media, the
Pioneer came second, reporting high transfer speeds.
In all the above cases, using DVD+R/RW and DVD-R/RW the K14L reported medium speeds but overall a stable performance.
Finally, in the DVD ripping test using a pressed DL movie, the Pioneer reported the lowest speed.
