CDR Tests
We mostly tested the Sanyo CRD- BP900P IDE CDR-W drive on it's capabilities to write CDs in different write speeds (4x, 8x, 12x) ,media and modes.
Feurio v1.34 beta properties:
- Reading properties:
- Recorder properties:
As we can see the Sanyo CRD-BP900P supports all current CDR/W writing and reading modes exept "RAW" writing and "OverBurn" (dispite Feurio says it does). As we have been told ,Sanyo will possibly add this feature with next firmware update. Let's head over to the CDR tests now:
Tests:
- Software used: Nero v5.0.0.9 / Padus DJ v2.00.419 / PrimoCD Plus
v1.1.356
- Media: Prodisc / Prostech / Ritek / Princo 8x, 12x / Basf / Maxell / Mitsui
Gold & SG / TDK / Verbatim / DataBank
4x-8x RW / Yamaha 4xRW / LeadData 4x RW / BTC 2x RW
Procedure:
We tested the Sanyo CRD-BP900P with all available writing modes and writing
speeds (4x,8x,12x) with different media doing different jobs:
- On the Fly CD Copies (for Data and Audio) (with
Plextor PX-40TS)
- Data CDs written at various writing modes (TAO, DAO, SAO)
- Multisessions CDs
- AudioCDs (from mp3 and wav files) + CD-Text CDs
- VideoCD
The Sanyo CRD-BP900P doesn't have any problem writing cds at 12x(max) and re-write them at 4x(max). Using several media the drive's performance was great and didn't had any compartibilty issues. Creating CDs at 12x ,with BURN-Proof enabled, gives you another feeling...for sure ;)
BURN-Proof Tests:
As we had mentioned previously in section 1, BURN-Proof technology should
be able to remove any worries you may have about buffer under runs. This is
what we did to calm those fears. We opened Nero v5.0.0.9 and prepared a DataCD
for writing it at 12x with BURN-Proof enabled.
Applications already running:
- 2 WinAMP windows running OpenGL plug-ins
- Padus DJ doing two images from both Plextor and Teac40x in the same HD
- Surfing at CDRInfo's forum and answering questions...
- HD Tach98 measuring same HD performance
- Sisoft Sandra 2000 benchmarking PC at the same time which all above programs
running.
Under normal circumstances, if you try to run all of the above programs simultaneously and starting writing CDs, the result is a buffer under run. However if you enable the BURN-Proof option you will nothing to fear….except possibly a power cut..!
Feurio v1.34 was used to copy an Audio CD from a Teac 540E to the Sanyo CRD-BP900P. When the writing bar indicator reached 20% the Ctrl+Alt+Del keys were pressed to halt the burning process. After a minute the escape key was selected. This was repeated between 20% to 40% (on the writing bar indicator) at intervals of 1%. After 40% we left the recording to continue until it had finished. No errors were reported during this test!!!! After creating the CD, using the above method (with the burn proof option enabled), we decided to see if the disc was as good as the original CD. How we did this?
EAC was used to "rip" wav files from both CDs. All of the wav files were then compared with the original CD. As we suspected the wav files were identical. We also checked the CD for possibly C2 errors using CD Speed 99 v0.66 beta (CD Quality mode) and no differences!
As previously stated, the BURN-Proof technology uses the location of the last successful sector and positions the Optical Pickup. As soon as the buffer is full again, the CD-Recorder will start recording again. According to the "Orange Book" specifications, the distance between the last successful sector and the new sector may not be more than 100 µm. The BURN-Proof technology ensures that the distance between the 2 sectors lies at around 40µm (i.e. well within the limits set by the Orange Book), and in this way data is written to disc without errors.
Verdict of CDR Results
After living with the Sanyo CRD-BP900P for almost 1 month, we can say for sure that the BURN-Proof works very well with the IDE interface. The drive has no problems when writing at maximum speed (12x). Buffer under runs are a distant memory! All tests were completed ok and didn't have many problems.
The only complaints from the CDR capabilities are:
a) The lack of "RAW" writing feature for CloneCD compatibility.
b) No "Overburn" features.
Hey don't be afraid to start playing your favourite game at the same time you burn a CD. This is a must for all gamers ;)
