CDR Tests - Page 1

The Sanyo CRD-BP1500P is the first CDR-W drive that supports up to 24x writing speed. As we have said earlier the 24x writing speed is not in the whole disc but in a specific part of the disc. You might think that the overal time of the a disc recording at 24x ZoneCLV writing speed with the Sanyo CRD-BP1500P would be much lower than with a real 24x drive. That's not true.

The average recording speed of the Sanyo CRD-BP1500P is around 22x, as Sanyo states. Below we post two compasion charts, taken from the Sanyo's website, showing the time differences between 16x CLV (Sanyo CRD-BP1400P) and 24x Z-CLV writing recorder (Sanyo CRD-BP1500P):

As you can see the needed time for burning a full 74min CD with CRD-BP1500P is around 227sec (3.78min) and the time differences from a 16x CLV recorder is around 100secs! A real 24x CLV recorder would make around 3.20mins to finish the task.

The same principal applies for 80min CDs.The Z-CLVrecorder makes around 241secs (4.02mins) and a real 16x CLV recorder around 333secs (5.55mins).

Using CD Speed v0.8 we didn't managed to get the 16x-24x Zone-CLV writing graph since the drive gave back only 16x CLV recording speed:

- Procedure:

We tested the Sanyo CRD-BP1500P with Nero v5.5.1.1, CloneCD v3.0.0.9, Padus DJ v3.00.780 software.

The main problem is/was that there aren't any 24x certified media available in the market now. Ricoh, Verbatim, Mitsui, Taiyo Yuden have announced 24x certified media, which however will ship in middle/end of May. Exactly at the time that 20x/24x recorders will hit the market. That means some of our CDR tests (and problems) might not be 100% correct, due to the use of only 16x certified media.

For the CDR tests we used: Verbatim 74min (16x) & 80min (16x), Mitsui 74min (16x), Taiyo Yuden 74min (16x), Prodisc 80min (16x) silver and Plextor/Verbatim/TDK 74min HS-RW media.

- CD-R Tests:
We created "DataCD" job with data slight higher than 74mins (74:03:65). We burned the same job with all 4 CDR-W drives:

As we can see the Sanyo CRD-BP1500P needs 3 more seconds to finish the test burn than CRD-BP1400P and 8more than PX-W1610A. The average CPU usage is a bit higher than the other 4 recorders.

- 80min CDs:
As with the previous test, we created a DataCD (80:01:47) and used the same media for all burns:

In this test Sanyo CRD-BP1500P again needs 2 more seconds to finish the task compared to the CRD-BP1400P. The CRD-BP4 has the highest time and again the PX-W1610A the lowest.
