For our tests we set each drive up as a master on our computer's second IDE channel.

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.

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