At the 40X (default) reading speed, the EHW-4048U drive is not the faster among the competitor drives since it gave only a 31.0X average reading speed. However under the 'Turbo' mode it superpasses the competition giving an impressive 37.43X average reading speed.

The seek times of the AOpen EHW-4048U are very close to each other either when the drive is set to 40X or to the 48X speed. The only difference can be seen at the Full Stroke test. The faster drive comes from WAITEC with 87ms for the random and 161ms for the full stroke.

With CD-R media, the EHW-4048U gets again the first place with an 37.64X average reading speed ('Turbo' mode). The seek times are also very good but the FRISBY II is faster...

- RW media: (Click to see the CD Speed Graph for 40X and 48X)

Again the 'Turbo' mode makes the difference and the EHW-4048U comes first with a 38.21X average reading speed. What is very impressive is that the drive reaches 50.74X at the end of the disc.
