Read Performance Part I - Data

Pressed CD Read Speeds

THG uses a pressed data CD nearly 74 minutes long (73:21.05 to be exact).

Both drives work in full CAV mode. This means that the CD spins at a constant speed and that the data transfer rate increases steadily as the writer moves from the center toward the outer edge of the CD. Each drive exceeds the promised maximum transfer rates of 48x and 40x.

Original CD Average Reading Speed Start Reading Speed End Reading Speed Access Times Random Access Times 1/3 Access Times Full

Waitec Frisby II 30,92X 20,36X 40,78X 88 ms 102 ms 174 ms
Yamaha CRW-F1UX 31,93X 18,65X 42,15X 127 ms 149 ms 260 ms
LG GCE-8480B 37,04X 17,96X 49,01X 96 ms 102 ms 171 ms
LG GCE-8400B 30,77X 15,76X 40,65X 96 ms 108 ms 177 ms

The average access time of both drives is decidedly racey at 96 milliseconds, which will save a lot of time when installing software.
