- 24x Zone-CLV against 16x CLV recording

Let's now see the most interesting test. How much time is needed for burning a full 74min/80min task at 24x Z-CLV recording speed? Our tests showed that for a full 74mins (74:03:65) task, the drive needs around 3:53mins (including lead-in/out time). That is very close to what Sanyo gives as the recording time. For a full 80min 80:01:47) task the drive needed around 4:13mins to complete the task:

- Testing various media at 24x Z-CLV writing speed

The majority of the tested media had several problems writing at 24x Z-CLV writing speed. The most common problem was that the drive could't calibrate the media and the burn didn't started at all since the "No Seek Complete" error message appeared. Sometimes the burn started and either completed in the expected time OR delayed to finish (we guess FlexSS-BP works and drops the writing speed).

In order to test the drive's ability to write at 24x , with 16x certified media, we done the following test: We tried to burn 5 CDs in ROW of each media at 24x writing speed in order to see the behavoir of Sanyo's CRD-BP1500P. For this test we used Nero 5.5.1.1 and the results showed:

Our tests showed that the Sanyo CRD-BP1500P didn't worked very good with almost all 16x certified tested CDs in 24x Z-CLV writing speed. This was something that we knew since Sanyo has warned us "..Most current 16x certified media will NOT work at 24x certified speed..". But we had to make the tests anyway since there aren't any 24x certified speed selling in the market now. When we have 24x certified media, recording tests will be repeated and our review will be updated. Stay tuned! The best results ,at 24x Z-CLV writing speed, came with Taiyo Yuden's 74min 16x media and Verbatim's DataLife Plus. The recorder denied working with TDK D-View 80min 16x and Infinity's 90min CDs. That's also that will be fixed with a newer firmware.

- Overburning Tests

We used 90min CDs (from Medea International) and 99min CDs (from Disc4You) in order to check the drive's ability to overburn. With the CD Speed 99 overburn test we got that drive can to up to 93mins only with 99mins. The drive refused to work with 90min CDs:

Afterwards we used Nero and confired the above results. We managed to burn up to 822mb of data in 99minutes CD (93:30:25).

- AudioCD Tests

We created several Audio CDs (including CD-Text). All of the CDs we created, were tested with the Plextor PX-40TS and Plextor's CD-Text compatible CD player. From what we saw, everything worked just fine.

- CloneCD Tests

The Sanyo CRD-BP1500P support DAO-RAW writing according to the CloneCD v3.0.0.9. The drive also suports "SAO-RAW" mode and simulation mode :). The CloneCD supports fully the 24x writing speed so you only have to select the writing speed.

We tried to backup protected CDs using various CD protections and our tests for "SafeDisc 1", "LaserLock" and "SecuROM 2" were succeful.

- SD2 report:
For the SD2 tests we used the "No One Lives For Ever" CD title. We used the Sanyo CRD-BP1500P both as reader/writer. The results were ,as expected, the same we had with the previous Sanyo drives:

The above test showed that the Sanyo CRD-BP1500P cannot produce SD2 working backups CDs...

- Buffer Underrun tests

The Sanyo CRD-BP1500P supports the second generation of the "BURN-Proof" technology ,which has 0 gap length. The drive worked fine even under heavy pressure from our side (100% CPU Usage). The "BURN-Proof" technology promises to make our burning life even more easier ;-).

- Verdict of CDR Results

The Sanyo's CRD-BP1500P 24x Zone-CLV recording engine sounded very fast from specifications and the real life tests confirmed it. Just place the CD, select 24x as the writing speed and after 3:51mins you will have ready a full 74min data/audio CD. As you have read earlier the drive had problems at 24x writing speed with 16x certified media, which from one way is natural. The firmware is still developing and the 24x certified media are coming in middle of May 2001. So we must wait a little longer till we can say with great confidence how the 24x Z-CLV writing mode performs.

The drive also supports overburning (up to 93mins) and DAO-RAW writing mode. Last the BURN-Proof technology worked perfectly and will save you from any possible possible buffer underruns (and coasters).
