Sanyo CRD-BP4-1400P CD-RW

2. Data Tests

Sanyo CRD-BP4/1400P CDR-W - Page 2

Data Tests

Test Method

- SCSI Mechanic v3.0x: This was used to compare the Sanyo's  I/O performance against other various CDR-W drives (see charts). We used a pressed CD containing PlexTools v1.06 for all of the tests.
- CD Speed 99 v0.80 was also used to check the drive performance with pressed CDs. For that test we used PlexTools v1.06 original CD.

- SCSI Mechanic v3.0 results

Both Sanyo drives are very fast and they managed to give out the best performance around. The SCSI model has the best "Average Sequential I/O" (4460kb/s) and the ATAPI model comes third with only 4268kb/s. We noticed a problem with the ATAPI model ?slowed down at the end of disc, which probably kept it back from delivering the even higher performance. The CRW2100E still manages to be very fast but BP4 takes the lead this time. On the other hand both Sanyo drives gave very low results on the "Average Same Sector I/O" (1787kb/s), which is much far away from the competition.

- CD Speed 99 v0.80 results

Using CD Speed 0.80, we can see that the BP4 clearly is the fastest 40x CDR-W drive . The BP1400P and CRW2100E come second with similar performance. Plextor of course cannot compete but we suspect when the PX-W1610A/S model arrives will have similar (or maybe even better performance).

The BP4 model gave back very low seek times. The BP1400P model comes very close so does the competition.

- CDR Media

Again BP4 model continues to lead the race and performs slight better than with pressed CDs and reaches 30.21x average when the BP1400P stays behind with only 28.5x. If you also notice the speed end result you will see that BP1400P model slows down and that costs the third place. This is a point, which Sanyo should look better and fix in the future.

Verdict of data tests

There is no doubt that the new Sanyo drives are the fastest CDR-W drives (compared to existing Yamaha CRW2100E mode). The BP4 model works very good and manages to outperform both ATAPI competitors. Also it delivers the lowest seek times again compared to the ATAPI competitors. The BP1400P model could perform better but the drive seems slow down at every CD we tested with..

Sanyo supports reading of 99min CDs so you will not have any problem with them. The problem of course is to write them since Sanyo drives stops writing at 93mins. We will talk about this later.. Last you will notice the low noise which both drives produce when reading at 40x speed compared to the annoying noise, which CRW2100E produces.
