CD Read Performance
CDs are still heavily used for distribution of most applications, so its fair to look at how these recorders function as CD-ROM drives.
The Pioneer drive makes a good showing in CD Winbench. The access time is particularly remarkable, approaching the performance of dedicated CD-ROM drives. On the other hand, the Sony drive has a slightly better CPU utilization than the Pioneer -- but the CPU utilization of both drives is small enough to be insignificant.
