Read Performance, Part 1: Data
Read Rates With Pressed CD
For the test we used a pressed data CD with a length of almost 74 minutes (73 minutes, 21.05 seconds, to be precise).
As the screenshot of Nero CD Speed shows, the drive works in full CAV mode. The maximum transfer rate of 44x was, however, not achieved. Despite that, the device is the quickest in this discipline in direct comparison with USB2.0 competitors such as Liteon's LXR-24101A and Waitec's Frisby II.
| Original CD | Average Reading Speed | Start Reading Speed | End Reading Speed | Access Times Random | Access Times 1/3 | Access Times Full |
|---|---|---|---|---|---|---|
| Liteon LXR24101A | 30,20X | 19,52X | 39,84X | 97 ms | 106 ms | 173 ms |
| 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 |
However, the access times achieved are not very exciting.
Read Rates With CDR
For this test we used a 1:1 copy of the aforementioned original CD. The blank TDK CD-R80 Metallic carries the following ATIP information:
ATIP: 97m 15s 17f
Disc Manufacturer: Ritek Co.
Reflective layer: Dye (Short strategy; e.g. phthalocyanine)
Media type: CD-Recordable
Recording Speeds: min. unknown - max. unknown
nominal capacity: 702.83 MB (79m 59s 73f / LBA: 359848)
The read rate and the access times were on the same level as those of the original CD. In the comparison, the Yamaha device does not score as well because of worse access times.
| CDR | Average Reading Speed | Start Reading Speed | End Reading Speed | Access Times Random | Access Times 1/3 | Access Times Full |

| Liteon LXR24101A | 30,18X | 20,05X | 39,69X | 102 ms | 111 ms | 173 ms |
| Waitec Frisby II | 30,97X | 20,40X | 40,72X | 93 ms | 99 ms | 183 ms |
