CloneCD Tests

Procedure

We used the latest CloneCD (v2.3.3.3) and 3 original CDs (Rally Masters, Euro2000 and Incoming) in order to test the reading time for both drives. We also tested the reading performance with the backups of the original CDs since the reading speed varies from original to backup media.

Note we couldn't use the drives for writing since they don't support "RAW" writing at present...All backups were created with the PleXWriter PX-W1210A at 12x writing speed.

Update:
Both drives work fine with the newest CloneCD v2.5.1.3 and SAO-RAW mode. This mean that you can used them, ONLY with SafeDisc and LaserLock protected CDs. ;)

Results:

a) SafeDisc Results:Euro 2000 (Total: 257982 sectors - 10141 bad sectors) - Reading Speed: Max

Drive	Firmware	CD	Fast Skip Error - O retries - Software Correction	Fast Skip Error - O retries - Hardware Correction	Intelligent Bad Sector Scanner	"Intelligent Bad Sector Scanner" + Best "Fast Skip Error" result
Sanyo CRD-BP900P	v3.20	Original	9:37 min	9:41 min	17:08 min	9:39 min
Sanyo CRD-BP900P	v3.20	Backup	10:20 min	10:26 min	16:24 min	10:30 min
Sanyo CRD-BP2	v2.21	Original	5:24 min	5:36 min	13:10 min	5:35 min
Sanyo CRD-BP2	v2.21	Backup	5:21 min	5:13 min	11:23 min	5:06 min

b) LaserLock Results: Rally Masters ( Total: 321528 sectors - 6317 bad sectors) - Reading Speed: Max

Drive	Firmware	CD	Fast Skip Error - O retries - Software Correction	Fast Skip Error - O retries - Hardware Correction	Intelligent Bad Sector Scanner	"Intelligent Bad Sector Scanner" + Best "Fast Skip Error" result
Sanyo CRD-BP900P	v3.20	Original	1:38:30 h	Fails the test	12:16 min	Fails the test
Sanyo CRD-BP900P	v3.20	Backup	13:15 min	13:25 min	10:11 min	9:58 min
Sanyo CRD-BP2	v2.21	Original	32:55 min	33:32 min	10:34 min	10:28 min
Sanyo CRD-BP2	v2.21	Backup	8:41 min	8:12 min	5:01 min	4:46 min

Note: The Sanyo CRD-BP900P with original Rally Masters CD failed to complete the reading task at the "Fast Skip Error-Hardware Correction" and "Intelligent Bad Scanner+Fast Skip Error" settings. No matter how many times we repeated we always had the same result..Not a good point the drive's CloneCD overall score.

c) SecuROM Results:
As CloneCD author emailed us both drives do not produce accurate subchannel data so cannot be used for reading such images...

Verdict of CloneCD Tests:
- In the SafeDisc test the SCSI model was faster than the IDE model by 78.81%!!.
- In the LaserLock test, the IDE model failed to complete when using the Fast Skip Error with Hardware correction. The drive stopped reading from the CD after some time, which shows a weakness.. In the other modes, the SCSI model was again faster by 17.83%. Overall in the CloneCD tests, the SCSI model takes the lead over the IDE model and is the winner!
