Yamaha CRW2200E CD-RW

3. Data Tests

Yamaha CRW2200E IDE CDR-W- Page 3

Data Tests

Test Method:
- SCSI Mechanic v3.0 & CD Speed 99 v0.80 Tests: With these tests we attempt to compare the I/O performance of Yamaha's CRW2200E to other various CDR-W drives (see charts) and we also checked the drive performance. In all of the following tests we used a pressed CD containing PlexTools v1.08 original CD.

- SCSI Mechanic v3.0 results:

The Yamaha CRW2200E didn't perform very well in the SCSI Mechanic tests. The drive had the lower score in "Average Sequential I/O" tests results and came 3rd in the "Average Random I/O" test. In the "Average Same Sector I/O" tests, the drive showed a superb performance and gave the best result ever tested in a CDR-W drive (25400 KB/s).

- CD Speed 99 results: (click here to see the CD Speed 99 graph)

The CD Speed 99 results confirmed our previous tests results. The Yamaha drive seems to be the slower among the 4 tested drives. The problem is that the drive starts reading at only 17.7X and ends the test at 38.7X test. The PleXWriter PX-W1610A seems performing best and Ricoh MP7200A follows very close, while the Sanyo CRD-BP1500P comes third.

The Yamaha 2200E is slower than the rest of the drives since the 40x max reading speed is reached at 80min CDs. Why does this happen? The drive is designed with that concept. Other manufacturers reach 40x reading speed at 74min CDs.

The seek times for Yamaha CRW2200E are very good compared to Plextor and Sanyo drive. The drive has an average 128ms Random Seek time and the Ricoh MP7200A is the champion in this test with only (!) 93ms.

- CD Speed 99 Results (CD-R Media): (click here to see the CD Speed 99 graph)

Things are better with CD-R media for the Yamaha CRW2200E. The drive's average reading speed is now 30.07X but also the rest drives are faster than with the pressed disc. Ricoh MP7200A takes the revenge from the pressed CD test and is the leader with 31.79X (Plextor is second with 31.56X). The speed gap is less, but still exists.
